General Ant Care & Information
Did you ever want a pet that you didn’t have to worry about if you went on vacation?
Ants can be left with just water and humming bird nectar for over 2 weeks with no impact to the health of the colony.
Ants Require:
- A Formicarium (ant nest)
- An Outworld (or foraging area)
- Food and water
- Heat cable/mat (in temperate or cooler locations)
Formicarium:
The Formicarium houses the ant colony, providing room and safety for the queen, workers, and brood (baby ants). The Formicarium also provides humidity which is essential to the ant’s brood. The Formicarium will need to be watered every 2-5 days depending on the type and size of the Formicarium.
A Formicarium can come in many shapes and sizes, and can be made from many different materials.
Outworld:
The Outworld, or foraging area, allows you to easily feed the ants without them escaping. It also provides a place for the ants to place their trash and they will often pile it in one corner for easy cleaning.
The Outworld can be made from almost any container as long as it is big enough that you can get one hand in it.
The Formicarium and Outworld are attached together with vinyl tubing. Some Formicariums have the outworld built into it.
Food and Water:
Different species may prefer different foods, but all ants require some sort of liquid sugar and protein.
The adult workers will almost exclusively eat sugars and the brood (ant young) will be fed mostly protein. Fruit is welcomed.
Sugars: Honey water, fruit juice, and hummingbird nectar are the most commonly used sugars. But oriole nectar, maple syrup mixed with water, and other sugars will likely also be accepted.
Protein: Protein is usually provided in the form of insects, but various cooked meats may also be used as treats.
Different species of ants tend to like different types of insects.
Some of the most commonly accepted insects include fruit flies, mealworms, crickets, spiders, white lawn moths, and other small soft insects.
If the insects are not cultured at home, it is advisable to freeze them for at least an hour to prevent any mites or pathogens from harming your ants.
You can also freeze excess insects that you catch or buy. The ants prefer the insects fresh, but will accept them frozen.
Mealworms and flightless fruit flies are easy to culture and raise.
Heat:
Most ants will require a heat cable running underneath one side of the Formicarium. Most ants in temperate locations will not survive more than a few months at constant room temperature. They require a location where they can warm up. An 15 watt reptile heating cable or heat mat works well. Heat also allows the brood to develop faster.
Hibernation:
In temperate locations there is winter and summer, and the ants use the winter to hibernate. Hibernation is a time of rest and re-energizing for the ants.
They will require at least 2 months of hibernation in a location where the temperature is between 5-12°C.
The ideal times are between the end of October and late March, but they will have no problem with hibernation from early December until late February.
If they slow down or become inactive when the temperatures get cool outside, don’t worry. It is normal.
Ensure the Formicarium is moist and that the ants have access to water and sugar water at all times in case they wake up for a few minutes.
After hibernation the workers and queen are rested and ready to “work like ants”.
Preventing Escape:
Escape prevention is usually a 1-2” layer on the top rim of your Formicarium. Usually made out of virgin olive oil, dried talc powder, or Fluon (Insect-a-slip). Barriers effectiveness will depend on the type of barrier and the species of ant.
Obtaining a Colony:
The easiest ways to get a colony is to get one from another hobbyist or to find a queen after her mating flight and letting her raise her own colony. Most mating flights in North America occur in May, July, and August.
More In-depth Information
Ant Housing
This part of the guide will go over Formicariums, hydration, heating, and escape barriers.
It is easy to make your own ant formicarium and outworld.
Formicariums can be built from many different materials such as Firebrick, Grout, Ytong (AAC), gypsum, hydrostone, and others. They offer a high visibility view of your ant colony.
Plaster can be used, but it molds very quickly, often within weeks.
There are step-by-step guides on how to build Formicariums out of different types of materials in this forum.
There are some companies that sell formicariums that are designed around long term ant care if you don’t wish to build your own.
There are hobbyists around the world who sell nests and outworlds.
A quick note about Uncle Milton and Gel farms. They are designed to hold worker ants for 2-6 months. Due to lack of humidity control, problems with collapsing tunnels, sanitation problems, and similar issues a queen and brood (ant young) will not survive for more than a few months. Many of those ant farms are just for observing the workers during their life span, not to hold an actual functioning colony with queen, eggs, larvae, pupae, and workers.
How much room?
If there is too much space, ants may start dumping garbage into the unused, empty chambers. Many people keep upgrading the nest as the colony grows. Many colonies with less than 50 workers only need 3-4 chambers. It is also possible to use sand to fill in the excess rooms to prevent the ants from using them until the colony grows more and empties the tunnels on their own.
Moving colonies
When the colony runs out of space and you need to expand or move them into a new nest. Connect the two nests together and wait, it may take a day or so for them to explore the new nest and think about moving. There are several ways to convince the colony to move if they don’t move themselves in a day or so.
Different species react differently to different methods. Typically changes heat, moisture, or light get them motivated into finding a new nesting site. For example, Camponotus (Carpenter ants) are easy to move simply by placing the heating cable on the new nest and cooling the old nest slightly. They will follow the heat.
Some species will follow the heat, or move away from it. Careful not to use too much heat or you could kill your ants.
Stop watering the old nest as it dries out the ants will likely move to the new nest as it has the humidity that they prefer.
If you cover the new nest, some species will move to the cover of darkness.
Nest Design
Many people love to design their own nest. It is fun to build or carve your design, whether they are tunnels or a completely different design.
Keep in mind certain aspects such as nest hydration, ventilation, and connecting the outworld.
Hydration:
Ants don’t live in bone dry locations. Some ant species prefer more moisture than others as well.
There are several ways to add water to your formicarium.
- If the nest is vertical or under a 45 degree angle, a reservoir molded, or carved into the formicarium would work
- If you use a method that involves pouring, you can make a chamber separate from the others and use a piece of 1/4” tubing to allow water to enter the chamber. Or you can drill a hole in the glass.
- Some nest materials such as ytong or firebrick rapidly absorb water and don’t require a water tunnel
Ventilation:
In smaller nests the tubing leading the outworld provides sufficient ventilation. Some types of nest medium allow small amounts of air to pass, such as firebrick and Ytong.
For large nests, an opening with fine stainless steel mesh will be needed. The opening is often on a side of the nest or in the glass. The mesh is epoxied or siliconed on so there is no chance of escape.
How to connect the Formicarium and Outworld:
Clear vinyl tubing like you see in plumbing is used to connect the formicarium to the outworld. The Formicarium and outworld each have their own piece of tubing that is connected in the middle with a larger piece of tubing.
Usually, a drill is used to drill a hole the same width as the vinyl. The hole is carefully dusted out and lightly moistened with water. Use 2-part epoxy as silicone has too much “give”, and push the tubing as far into the hole as you can. Add another layer of epoxy on the outside around the tubing/nest joint.
Use the same size of vinyl tubing for the outworld and the formicarium. Then you can use a wider piece of vinyl to connect the two. Water and/or heat may help in connecting the ends, although it will probably take scissors to get them apart again.
For example, I use 5/16” x 7/16” on my formicarium and outworld, and I use a 3/8” x 1/2” piece of vinyl as a connector.
You can also buy a plastic connector.
Tunnel depth
Ants come in many different sizes, so the tunnels they make also vary.
The tunnels should be wide enough for 3 workers side by side and about twice their height. The chambers should be at least twice as long as the queen and as wide as the queen is long. Try not to go over twice the queen’s length for the width of the chambers or the ants may not feel secure. The chambers can be as long as you want. They can be square, rectangular, oval, curved, or any shape.
The chambers should be twice as deep as the queen is tall. Even 3x her height will work as this will allow the ants to pile brood high, sit on top of it, while leaving plenty of space to move around.
Heating
If your house is under 22° C then your colony will likely need additional heating. Some species need more heat than others. Myrmica are heat lovers, while some species of Lasius place their brood in moderate heat and excess workers hang out in cooler areas.
The best heating method is to use a heating cable, or a heating pad meant for reptiles. Place it under one corner/side of the formicarium. This will create a heat gradient with heat on one side and cooler locations on the other side. This will allow the ants to choose what temperature they want.
Use a heating cable no hotter than a 15 watt. You can leave them plugged in all of the time, or place them on a timer to mimic the suns heat.
You can place the heating cable/mat under the nest, or on the glass.
If the ants are as far as possible from the heat, then it is too warm. Move it further away from the center of the nest and reduce the time it is on.
Heating lamps have been used in the past with success (and some failure). You can try using a ceramic heat emitter or a darkly colored bulb, perhaps the infrared night bulbs for reptiles, to prevent your colony from stressing over the light while providing heat.
Observe your colony carefully for any indications of stress due to overheating.
Outworld
Outworlds are necessary for the ants to keep the nest clean, to allow the ants some area to explore, and to make things easier for you when feeding and cleaning. Some people go all out with their outworlds and decorate them, or even grow plants in them. You can, however, just use a simple, empty plastic box.
Mini food dishes make feeding and cleaning up easier. The inserts inside some pop bottles or aluminum foil work well for dishes for feeding.
Most outworlds have secure lids with ventilation holes, but others are left open. Regardless of which method you choose, you should have a barrier to prevent your ants from escaping.
Barriers
Olive oil
Extra virgin olive oil is probably the most used. Take some paper towel or a cotton ball, dab it in the oil, and “paint” a light sheen about an inch wide along the top rim of the outworld. Even just using your finger to wipe it on will work. Allow it to settle for a few hours before use since it tends to drip for a while and can drown ants caught in it. If it drips, just wipe up the excess with a clean paper towel. It holds some species with ease, such as Myrmica and Formica. Although there are some ants who have no trouble walking over it. The oil has to be re-applied every 2-3 weeks.
Talcum powder
A homemade barrier uses baby powder (those made from talcum powder) and isopropyl (rubbing) alcohol. Mix it together to make a paste, paint an inch-thick band along the top and allow it to dry. Alcohol evaporates quickly so it shouldn’t be long until the powder is stuck to the side. The particles of the powder aren’t stuck on there very well and even an ant’s weight will cause them to fall off. This is temporary, as well, and some ants don’t seem to have an issue walking over it. Be careful as the more ants trying to cross it, the faster it deteriorates. If you have a large colony it won’t be long before the ants clear a path.
Fluon or Insect-a-slip
Insect-a-slip, or liquid Teflon, is one of the best barriers out there. It comes in a small bottle and is pretty pricey for the amount you get. Before you let that deter you, though, consider that one layer uses only a fraction of the bottle and lasts at the very least for some months. It does degrade faster with higher humidity or at low temperatures. Each application should last around six months. If you can bring yourself to spend $20 for a small bottle of the stuff, it is well worth it.
Feeding
Freezing before feeding
Insects and arthropods can carry mites, diseases, or parasites that can be harmful to your queen/colony. It is highly recommended to freeze any food for a few hours at least before feeding. Many people store insects in the freezer until it is feeding time. They will last for a long time in there, but like other foods, freezing and thawing repeatedly can cause them to spoil
Feeding live insects that you yourself have raised is acceptable. Flightless fruit flies are commonly dumped into an outworld to let the ants hunt. Store bought insects may carry mites, crickets are well known to carry mites.
Feeding Dishes
Using feeding plates or containers minimizes the cleanup and chances of mold. Feeding plates can be made from anything from tinfoil, pieces of cardboard, or the inserts in some pop bottle lids.
Another alternative is to soak cotton balls in food such as sugar water when offering it to prevent drowning.
Waterers are excellent ways to water, or offer liquid food. Easily made or bought.
They can be bought from tarheelants.com
Link on how to make them: http://forum.formiculture.com/index.php/topic/108-how-to-build-an-ant-waterer-or-liquid-feeder/
Offer A Varied Diet
Ants like a varied diet. If you are only giving them crickets day in and day out you may find that don’t accept them as easily or at all after a while. This is because, as with all foods, each individual type of arthropod has its own nutritional content and a varied diet gives them more of the nutrients they need.
It is highly recommended to offer your ants a varied and balanced diet for your ant colony. Some good sources of sugar are honey, hummingbird nectar, table sugar, potentially fruits (careful of pesticides), and maple syrup.
Tear the body and trim wings
I find it’s also a good idea, especially with young colonies, to cut up or tear open any insect prey before feeding. It gives the smaller, weaker nanitic workers an easier way inside to the good stuff. This is especially true for harder bodied insects such as beetles Trimming off any wings or spindly legs (like those on crane flies) prior to feeding can help prevent a mess in the outworld.
Test tubes/tubing as feeding tubes
Utilizing unused test tubes or lengths of aquarium tubing, you can effectively create a feeding bottle. Simply fill the tube with your liquid food, plug the open ends with cotton, and voila, the ants can drink without drowning, and you don’t have to worry about replacing it any time soon unless it molds. If your honey or syrup is too thick to do this with, thinning it out with some water is effective.
Over feeding and under feeding
Be advised that it is possible to over- or under-feed your ants. Over-feeding might give them too much food, which they will store, and it may go moldy in the nest. If the ants remove it, great, but sometimes they don’t. Under-feeding isn’t generally a huge problem, but if you are under-feeding you may notice your newest workers being smaller than usual. This is because the larvae are underfed, just like the queen’s first brood, don’t get enough of the stuff they need to grow to normal size.
Underfeeding is usually not a fatal error for your ants, unless you forget to feed them for a month or so. Ants are hardy creatures with rather small stomachs and the ability to store food in their second stomach. Ants are marvelously efficient creatures.
Most ants will collect as much as they need and dump the excess in the outworld.
Note: if the colony has too much room in the nest, they may use a spare chamber as a garbage heap. As the colony grows they will likely empty it out.
Preferred foods
Like people, ants have preferred foods. It varies from species to species, and even season by season or with the stage their brood is in.
Link to a list of preferred foods by species: http://antfarm.yuku....es#.Urn8oLTwrYR
Hibernation
In the winter in temperate locations there are often no ants active in the wild. It is a time when ants rest and re-energize themselves.
Generally, in the wild, a colony will store food, then sometime in the fall or early winter, seal off the nest. No foraging takes place, brood stop developing, the queen stops laying eggs, and everyone seems to go to sleep; but what about in captivity? What happens if you don’t let them hibernate? Where can you place them for the winter? What kind of environment do they need?
What about in captivity?
In captivity, the same thing happens as in the wild. It’s a natural cycle ants go through whether you hibernate them or not. If you choose to keep them heated and lit up during the winter, you’ll likely notice less activity, no or slow brood development, no egg laying, and less foraging. It’s probably best for their health if you just let them sleep.
What happens if I don’t allow them to hibernate or keep them heated over the winter?
If you don’t let them hibernate, then there is a chance they will suffer for it. Some colonies stay perfectly healthy, others start having increased worker deaths, and all around poor colony health. The queen tends to lead a much shorter life without hibernation. It is strongly recommended to let them hibernate for at least 2 months, although 3 months is preferable.
How do I put them into hibernation?
There are several ways to hibernate your ants. They require a temperature between 2-8 °C.
An unheated room in a cool basement will work, and many people put their ants in the fridge. Coolers can be used with success, either the electric version or using bottles of ice to keep the temperature low. It is strongly suggested to place a thermometer on top of the nest to monitor it.
Check them once a week or so to ensure they have adequate water and that they aren’t freezing to death, but otherwise leave them alone.
If you have an insulated/heated garage or shed, put a thermometer in it to monitor the temperate over the winter; anything lower than 0°C may be hazardous to their health. The temperature shouldn’t get above 8° C
What do I do for them during hibernation?
You should offer some sweets during the hibernation period just in case anyone wakes up and goes foraging. It’s not all that common, but not completely unheard of either. The thing you need to be most concerned with is water. If they run out and the nest dries up, they can die very quickly. Make sure they stay moist and have access to water at all times.
Some ants may appear to be dead during hibernation, but they may just be sleeping. If you’re concerned, you can remove the ant, warm it up, and check it. If it appears dead, place it on a wet paper towel for a few hours. While it is possible for ants to die during hibernation, I wouldn’t really worry myself over it until spring. It can take a day or so for the ant to wake up.
Starting Your Own Colony
Catching A Queen
An ant nest will produce winged ants called alates once a year (the time varies depending on the species). These are princes and princesses that will embark on the mating flight at the right time.
Most alates will only mate when they have flown high into the sky, so if you disturb an ant hill and see winged ants, don’t bother collecting them. They haven’t mated and are infertile. It is nearly impossible to get them to mate in captivity.
Alates usually fly just after a rain or in high humidity. Each species seems to send the alates out on the same day as others of their species. There may be 1-5 flights over a 1-3 week period.
Queens can vary greatly in size from one species to the next. Some are only 2mm, while others can reach 14mm.
To Find The Queens
It is easiest to find them on cement, usually a sidewalk or driveway as the queens run around trying to find a good place to dig their new home. You may walk along the sidewalk for days and weeks and see nothing, but one day you will see dozens.
Other ways to find queens include turning over small rocks or pieces of wood. New queens will crawl under these to start a new colony. Even pulling apart rotten logs, or peeling the bark off of a dead tree can yield the wood-dwelling species.
The following thread explains in-depth how to find newly mated queens.
http://www.formicult...y-mated-queens/
Wings
A Queen will usually shed her wings shortly after landing. Sometimes the queens will keep their wings for years even if they are mated.
Some people say queens with wings are infertile – not true. There are flourishing colonies in which the queens have wings, and many infertile queens who have shed their wings.
Queen, Prince, or worker?
A queen is larger than the males. The males have a very pointy gaster (abdomen) and are only 1/3 of the queen’s size. The males also have extremely tiny heads with huge eyes.
After mating the males die, if they don’t mate they will only live 1-3 days without the colony to feed them. Males always keep their wings.
The queens and princes have larger thoraxes (mid-sections) than the workers do.
Flight Times
Around the world ants of the same species tend to fly in the same time period. In North America, Camponotus fly in spring, Formica in August, etc.
You may search for weeks with nothing, and then one day you will suddenly see dozens of them.
Some species are hard to find because they aim their flight to dense forests, or even fly at night.
This site lists the months that certain species were spotted flying. http://forum.formicu...hart/#entry1004
ID Your Ant
Once you have a queen, the first thing to do is to get your ant identified. The easiest way to do this is to take a few pictures, a measurement (in millimeters), and create a somewhat detailed description of the ant and where you found it (location based on the nearest large city is extremely important) and post it on www.formiculture.com or http://antfarm.yuku....ku.com. Within a day or two someone will likely be able to ID your ant down to genus, perhaps even species.
Usually genus is enough to get a clear idea on how to care for your ant. Some ants, of course, are social parasites or semi-claustral and can make their care requirements a little harder to meet. I’ll get more in-depth on these two stipulations further down.
Queen Care
Caring for a queen can be a bit different than caring for a mature colony. Different techniques used for the different types of queens. Some queens can be trickier than others or have special nesting requirements, food requirements, or something else.
In more northern locations, many ants that fly in or after August will wait until spring to lay eggs. A 2 month hibernation in the fridge may fool the queen into thinking it is spring.
Note: Even if you find a queen, they may be infertile, and in the first year or two many die for no apparent reason.
Differences Among Queens
There are 3 different categories of queens: fully-claustral, semi-claustral, and socially parasitic. Each has slightly different methods of care.
Fully-claustral
Fully-claustral queens are typically bulkier than semi-claustral queens, with smaller heads proportionately to social parasites and semi-claustral. The reason for this is that they do not forage or need to fight during the founding stages since they spend their entire time in the nest. These queens are the easiest to care for and the most important things to keep in mind are humidity and disturbances; you can typically just put them into a new home and forget about them for a month. They nourish themselves through fat and food stores along with metabolizing their wing muscles.
Semi-claustral
Semi-claustral queens are usually thinner and require a foraging area and access to food during the founding stages. These queens can be trickier, but are fun to watch. Food requirements vary from species to species, but for the most part the diet is comprised of sugars and insects.
Social parasites
Social parasites are the third type of queen ant. These queens are usually somewhat stocky like the fully-claustral queen, but have larger heads and mandibles in proportion to the thorax compared to their fully-claustral counterparts. Their gaster is usually smaller. These queens need a host in order to found a colony. In the wild they invade a colony of their preferred host species, kill the queen, and use the workforce to raise her own brood. In order to care for these ants properly you will need to identify their host, collect brood (ant pupae or larvae) and give them to her. Once the workers emerge, they will think the queen is theirs and they will take care of her.
Note that adult workers from different colonies have different scents, introducing adult workers to a different queen may result in a fight that can kill your queen.
In a small handful of species, the queen may accept adult workers. First you need to refrigerate both the queen and her host workers for a few days. The longer workers are separated from their colony, the more likely they are to accept a new queen. After this is done, add one worker to the queen while they are all still in the refrigerator. The cold slows them down and usually limits their aggression to posturing. In some parasitic species the queen will kill the worker in order to use the worker’s scent to infiltrate the colony, if this happens, do not be alarmed. Add a second worker, watch for signs of aggression, if it escalates to the point of combat, separate them and try again later. If all goes smoothly and you get the workers introduced to the queen without incident, leave them in the refrigerator for a few more days in order to allow the scent to really stick and get the workers used to their new queen.

Queen Setups
Among the most commonly asked questions is “What can I put her in?” The answer is just about anything. As long as your semi-claustral queens can forage, and your fully-claustral queens feel secure, just ensure that there is an easy way to maintain the nest, adequate humidity, and surface to view them from.
Common techniques and items used: Also see Various Setups for Founding Queens - http://www.formicult...ens/#entry15089
Test tube setup
The test tube setup is extremely cheap and easy to make while providing all of the key things a good claustral chamber needs. You fill around 1/3 or ½ of the tube with water, plug it with a piece of cotton, insert the queen, and then plug the open end with a dry piece of cotton. The water is needed for them to drink, and to maintain humidity or else they will dry out and die. The piece of cotton inside holds back the water to prevent drowning while also allowing an easy drink for your new pet. You can make it tighter or looser fitting as a way to help increase or lower humidity levels in the tube, too. The piece of dry cotton on the end allows air flow so she can breathe, and also keeps her from escaping. The test tube setup is nearly perfect for any queen or small colony. You can even add a bit of dirt or sand to give it a more natural look or feel, or for queens who like to dig. Dirt also helps prevent deaths from flooding most commonly encountered with small species such as Solenopsis molesta.
Once the queen has workers, you can place the tube in a plastic/glass container to let them forage. They can live like this as long as the tube has water. If the tube runs out of water, place a new tube in the container and they will likely move once the water in the original tube is gone.
Test tube alternatives
A common replacement for test tubes is vinyl aquarium tubing. You can easily find 10-foot lengths of this stuff at your local Home Depot or hardware store. Cut it into smaller (3-6 inch) segments, plug one open end with cotton, clay, or something else, and follow the above procedure for the test tube setup.
Another replacement is a prescription pill bottle. You can usually get them for free from your local pharmacy, and they can make wonderful impromptu test tubes.
Firebrick/ytong/pumice/grout chamber
Another option is a firebrick/ytong/grout/pumice setup. Use a small block molded or carved with small chambers and covered with a piece of glass. All you want is one, or possibly 2 chambers in the beginning. In general, the amount of space given to a queen is 1.5x her body length, and 1.5x her height. This gives her adequate room to maneuver, while also making sure she feels secure. Mold or carve little tunnels to place tubing into to allow each queen access to its own outworld – like a mini nest. This is good for small colonies, or for semi-claustral queens.
Ensure you keep the nest moist.
Household containers
Pretty much anything you find around the house can work as long as you ensure that it is cleaned out, first. A jar, with a layer of dirt on the bottom, or filled all the way up, can be a wonderfully successful environment, and provides plenty of space for quite a long time. There is record of someone who once crumpled a piece of damp paper towel up and placed it into a small cup for a Camponotus queen and she was able to successfully raise her first workers in this.
Feeding Queens
Fully-claustral
Ultimately, feeding a fully-claustral queen is a personal choice. They don’t require any food for many months because they typically have fat and food stores, and will metabolize their wing muscles for nourishment. If you do decide to feed them, it’s common that they won’t accept protein in the form of insects, but they usually go for sweets. There are, of course, exceptions to this rule; some Aphaenogaster queens ravaged any termites offered, for instance, but this isn’t always or even typically the case. Usually a dab of honey, maple syrup, or sugar-water will suffice. One way to offer protein is to mix whey protein shake powder in with maple syrup/water or a hummingbird nectar mix and many queens will accept it. It’s a great source for protein, but do note that you likely won’t see any increase in numbers or size of nanitic workers when feeding a queen.
Semi-claustral
Semi-claustral queens need food. You can still use a typical test tube setup for them, but instead of sealing it off with cotton, leave it open and place it into a plastic/glass box. Put food into the box, and the queen will find it and take it back to her tube. These queens usually will accept protein, especially when larvae are present, and in some species, seeds such as sunflower seeds. Giving her some sugar isn’t a bad idea either, in the form of sugar water or hummingbird nectar.
It is possible leave the queen in a sealed tube and place food inside with them. Ensure you use some tinfoil or paper as a feeding plate to prevent dirtying the tube.
Nanitic Workers (nanitic workers are a queens first workers, they are much smaller than normal)
When nanitics arrive, it’s time to start thinking about food even if your queen is fully-claustral. You likely won’t need to feed them for several days. When the nanitic workers begin trying to open the nest by tearing at the cotton plug sealing them in, you know they are very hungry. Offer some sugar water or hummingbird nectar, and maybe a small insect. Something soft and/or torn open with some needles/pins/tweezers to allow the smaller, weaker ants’ access to the good stuff. Many young colonies will love pieces of large spiders, or whole small spiders with a tear in the body. Tearing off the meaty, metathoracic legs of a cricket and tearing open the tibia slightly will give them access to the muscle tissue within which is rich in protein. Fruit flies and termites work well too.
Freezing before feeding
Insects and arthropods can carry mites, diseases, or parasites that can be harmful to your queen/colony. It is highly recommended to freeze any food for a few hours at least before feeding. Many people store insects in the freezer until it is feeding time. They will last for a long time in there, but like other foods, freezing and thawing repeatedly can cause them to spoil
Feeding live insects that you yourself have raised is acceptable. Flightless fruit flies are commonly dumped into an outworld to let the ants hunt. Store bought insects may carry mites, crickets are well known to carry mites.
Methods of Feeding
There are several ways to feed a queen/colony while minimizing the mess.
Cut a Q-tip in half, dip one side of the cotton end into the liquid, and put it in. Lock it in place using the cotton plug dry side against the wall.
Place all food onto a small piece of tin-foil, remove the foil once the queen has eaten her fill.
Whenever using a liquid/semi-liquid, such as honey, syrup, etc, ensure you soak it into a small piece of cotton to prevent drowning deaths.
There can be problems if you’re just dropping drops of honey and what not into the test tube. Sometimes ants can get stuck and drown in those drops, or they’ll walk through them and make a huge mess in the tube which can cause mold.
Queen Problems
Sometimes not everything goes smoothly with your queens. Problems do occasionally crop up. Some are common while others are rare.
Settling/Cotton tugging
Often when the queen first goes into the tube she will start tearing at the cotton plug. This behavior may last a week or more, but you just need to be patient and leave her alone. Sensory deprivation can help get her to settle down and settle in a bit faster. Put her in a completely dark place where she won’t be disturbed, and give her at least three days before you check on her. There are instances where she will do this until she’s dead, while it is sad, it does happen, and if it goes on any longer than a week, consider using a different kind of setup for her. Many Pogonomyrmex queens, for instance, do not settle well in test tubes and usually perform far better in a dirt setup. Or when there is dirt in the test tube.
Then there are times where a queen gets a rough disturbance like being dropped and she may start tearing at the cotton all over again. This happens because she deems her nest to be unsafe and likely is prepared to abandon her brood and start over. Give her a few days of sensory deprivation, and maybe a day in the refrigerator if necessary to try to calm her down.
Fungi
Fungi can come in all different colors and shapes. Zombie-ant fungus, insect-infecting Aspergillus flavus, common house molds, etc. can all be harmful and fatal to an ant or a colony of ants. If you spot mold in one of your formicariums, I suggest moving the colony as soon as possible. If you happen to be having worker or queen die-offs, leave the dead specimens in a container with a lid for a couple of days and see if they sprout any fungus. Some fungi will grow within an adult ant and end up eating it inside out. If after a day or two in a sealed container they do not sprout anything, it is likely that a fungus isn’t the cause of death.
Some funguses are deadly, others don’t seem to bother the ants.
Dirty tube
Ants poop just like you and me. Sometimes you get lucky and no mold ever sprouts inside your test tube, but after a while you’ll notice the cotton and water looking yellow to brown in color. That’s ant excrement and it can be gross to look at it. It shouldn’t be harmful to your ants, but it is recommended to move them once the water gets contaminated.
Parasites
Sometimes your queen’s parent colony will have a mite infestation, or she picked some mites before you found her, or perhaps some food you gave her was contaminated. In any case, if you see extremely tiny (like pinhead size) dots on your queen or running around your tube, it’s likely you have mites. Unfortunately there’s not much that can be done about a mite infestation in ants. With reptiles, they have mite powders that will dry the mites up without harming your pet, but I’m afraid these products are just as likely to kill your ant(s) as they are to kill the mites. Fortunately not all mites are detrimental to your ants so it may not be a problem at all. One thing you can try is offering lemon or orange juice (freshly squeezed from the fruit) on some cotton. Ants are smart, they know if they have a problem and how to deal with it. It's possible they'll use the acidic lemon juice to dry out and kill the mites taking care of the problem on their own. With 1-2 larger mites on a newly found queen, it may be possible to remove the mites with tweezers.
Some people have also found dead queens with small, larva-looking things in the test tubes. These are usually parasitic flies or even wasps that laid eggs on or in the queen. Once they hatch, they can chew through the queen's gaster causing death, and will usually eat their victim after. There's no way to know if your queen has a parasitic wasp or fly larva in them, and nothing you can do after it kills your queen.
Brood problems
Sometimes everything is going right with your queen, but you notice the brood keeps disappearing, or she constantly has a pile of fresh eggs, or you even catch her eating her brood. This can be caused by stress or environmental factors killing the brood. Sometimes queens are just fail moms, though. If your queen is eating her brood, or potentially eating her brood, I suggest taking a close look at the environment they’re in and making sure there is no reason the brood is dying. If there is no apparent reason for brood deaths, ensure that she is being left alone. Only check on her once a week, and put her somewhere where she won’t be bumped, exposed to vibrations or any other disturbances. If all of this is done and she still isn’t producing, or is eating her brood, consider her a fail mom. In this case, there is no harm in keeping her until she dies or perhaps gets lucky and produces some offspring. Offering her some callow workers of the same species may make the colony successful.
You can also attempt to introduce adult, non-callow workers. Some ants are more accepting than others, so always be wary and only do this if left with absolutely no choice. Stick the queen and any collected workers (of the same species!) in the fridge for a few hours. Introduce one to the queen and observe them for a few minutes. Chilling them in this way typically reduces aggression to only posturing, but be prepared to break up a fight. Leave them in there until they at least stop showing aggression before introducing more. The workers will be able to assist the queen in raising her brood.
To add to this, queens routinely feed eggs to larvae. It is one of the more common ways for a queen to feed the larvae. Sometimes queens simply lay a bundle of infertile eggs that are just for consumption and slowly consume them. It is common for a queen to lay a sizable pile of eggs, but end up with only one large larvae with no eggs or any other brood. The larvae will usually pupate and eclose, so no problem.
Spontaneous death
Sometimes a queen just dies for no apparent cause. It could be genetic, a disease, reaction to fumes, residues, or the stress of being caught, or some microscopic or nearly microscope life-form such as a mite. If you fail to find any likely cause of a queen’s death, and no fungus sprouts after a couple of days in a clean, sealed container, chalk it up to luck of the draw.
Queens who are infertile usually die within days, although they can live up to year or more. Queens who are infertile will lay eggs, they will develop into males with wings. Only fertile queens can produce workers.
For this reason, many people catch 3-5 queens to ensure they get a couple that survive.
Colony care
Caring for a colony in a formicarium is different than caring for a single queen or fledgling colony. They will need a variety of foods, plenty of space, an outworld, preferably a moisture gradient, and a temperature gradient.
There are some things differences between catching a wild, mature colony and rearing a colony from a new queen.
Mature vs. new
Many people find a mature colony and are able to catch a queen from it. This is fine in as long as you do It properly and I’m sure most enthusiasts would agree.
Never take a queen without workers
Never take a queen from a colony without also taking her workers. After workers start pampering and caring for the queen, it is unlikely she will survive if she is removed from them. They tend to become wholly dependent upon their workers, so if you can’t catch most or the entire workforce with a queen, don’t collect a mature colony. Polygynous species are an exception. Catching only a portion of the queens and workers from a polygynous colony will allow the remaining portion of the colony to live on and give you a mature colony to keep and observe.
Collection of a colony
If you have to dig up a colony to get it, be aware that most ants dig many feet below the surface over a wide area so it is unlikely you will locate the queen, and even if you do, you could kill her. Ants nesting in wood are a different matter as they are usually easier to obtain. But most wood-nesting ants practice polydomy, so it’s possible the queen isn’t even in the log you’re tearing apart.
Sometimes colonies will be just underneath a rock or piece of wood, if you turn it over you might see the queen. If you see her, catch her first, and then collect as many workers and brood as possible.
Stress of catpure
Another problem that can arise is stress. A mature colony has likely lived and thrived in the wild for some years and a sudden home invasion, destruction, and capture can be extremely stressful for a colony. New queens from nuptial flights adapt to captivity far more easily than a mature colony. Sometimes a mature colony will have a large worker die-off after collection, so be prepared. A wild colony will probably take several days to 2-3 weeks to start eating and settle in.
Queens don’t live forever
There is almost no way to determine the age of a queen. The queens you find in a mature colony are possibly quite old; some can live upwards of 12 years! So be advised that without knowing the age of the queen in a mature colony, it’s possible she and her colony will be approaching the ends of their lives.
