They need an outworld.
A place to take their trash, otherwise their excrement, and their food waste just pile up and rot where they are trying to live. It is no better for them than it is for us to live in our own filth.
While i find they will pick their own toilets which may or may not be easy for us to clean. When given a definite outworld space apart from their nest, they will generally transport their trash out to it.
Though with ants there are complexities to take into account. For example if they have way too much open empty nest space for how big the colony is. They might start filling up the extra nest space with their trash if they don't like too much big empty space around them. rather than talking it to a provided outworld.
Additionally an outworld can allow you to give food and clean out trash without needing to directly disturb the nest(vibrations, they don't like their nest being vibrated, they think something is about to dig in and eat them) too much to do so.
In a tiny setup for a small colony, something like a THA mini hearth is an all in one setup. You can't exactly take the lid off without the nest becoming aware.
But you can attach an outworld to it using a bit of tube like so:
Additionally a larger outworld can start to allow the ants to show you more of what their real world foraging behavior looks like.
In a small enough space their sent trail communications don't really work the same what with the "line" crisscrossing back and forth over itself again and again in a tiny little space.
once i opened up the outwrold space to this:
their behavior is strikingly different.
they "hang out" in the small and med outworlds. but they explore and forage in the large outworld.
Additionally this image was from when i first hooked it up. The trash pile is still there in the left front corner of the med outworld.
The first group activity within about 15 min of hooking it up, was to move the trash pile to the far right side of the large outworld. As far from the nest as it gets, they clearly want to keep the trash away from their nest. They take full advantage of as much outworld space as i give them.
And this is for a small 20+ colony that's now at about 40 or so. I intend to move them into larger nests as needed, but i plan to keep expanding their outworld space as much as i can.
I am also noob to ants.
Here's my notes so far in case it helps.
