Tetramorium immigrans is established and poses no big threat now, Mdrogun

I believe this statement is false, as they are still fairly destructive to native ant populations.  Feel free to correct me if I'm wrong, but I'm sure they are still a problem.

 

Yeah, sorry I'm not familiar with the forum and didn't know you couldn't delete the posts... I wasn't serious with that one. I apologize ':|

Invasive (meaning present, but not native) species shouldn't be outside of their natural habitat.  

You're seriously one of the most helpful and knowledgeable people on this forum, but I'm sorry, this is wrong.

 

species can be introduced but not invasive. They only become invasive when they are introduced, spread prolifically and destructively. It's kind of an arbitrary term, and I would definitely agree T. immigrans is invasive, but I just like to be a stickler to definitions  .

 

They've been here for 200 years so they're pretty much established at this point. Yes they are extremely dominant in urban environments but that's pretty much about it. Not to mention they actually kill Solenopsis invicta colonies.

Their dominance in urban and suburban environments is unparalleled and destructive to local populations of ants. If your house was burning down would you throw more matches on it cause "eh, it's already on fire, doesn't really matter."? Probably not.

 

I don't understand your argument that they're OK because they kill Solenopsis invicta. All that tells me is that Tetramorium immigrans is a more destructive and threatening invasive species than Solenopsis invicta.

 

 

If the house was on fire then throwing a few matches on it would literally do nothing. Which is my point. This fire has been raging for 200 years now, so its spread quite far and has plenty of fuel. While there's nothing you can do on about it on the large scale. You can still try what AnthonyP163 is doing and eradicate them on a small scale. His efforts have actually yielded positive results. As the article I linked mentions, the fact that they kill invicta colonies may deter the northward advance of invicta (well at least as northward as the climate permits).

 

What I'm getting at is that he doesn't need to kill them and if he wants he could start a colony.

In my area, though Tetramorium is very abundant in the dry environment that the sidewalks provide, anywhere near the grass is more dominated by the other species of ants. I know in Vancouver in particular Lasius americanus easily dominate over Tetramorium. At least in my area they seem more relaxed and don't harm the local species too much.

Keeping them is better than just letting them live outside; killing is just the best option, out of them all, to deal with non-native things.

Wow I just wanted to now what my queen was never expected such a heated debate

I didn't think it was heated.  This usually happens fairly often, haha.  Everyone has different opinions on everything.

As you can see, ants mean a lot to us. this species should've been treated like fire ants when they entered the states. but they weren't and are destroying the local ant species in the Pacifica northwest and most likely in other parts of the states.

Not heated at all, just a friendly discussion.

[camponotuskeeper]

Okay I may have to readjust my definition of a heated debate if this was a friendly discussion. But it was very interesting and cool to see everyone’s opinion.

[camponotuskeeper]

So based on your guys discussion tetramorium immigrans is only a big threat to natives around cities?

[PacificNorthWestern]

no, but actually yes. Anywhere where we are, there is most likely tetramorium. in neighborhoods, around houses, in cities in your backyard. These are ants. They don't live in just cities they are wild creatures that live in the wild. They don't have a specific habitat, in the ground, under rocks, under logs in metal pipes, anywhere they can live, they will try to live in.

[PacificNorthWestern]

and if that means killing another ant colony, that other ant colony is as good as dead

[camponotuskeeper]

Caught more of what I believe are tetramorium immigrans just wanted to make sure

here are the pics

[camponotuskeeper]

Found in walla walla Washington on a back patio
At about 6:30 I’m the morning

[camponotuskeeper]

Coloration is black with paler under the gaster and bands around the gaster
Does not appear to have hairs on the abdomen

AntsCanada prefers to call them "naturalized invaders", yet I took a walk one early morning and saw this: https://www.youtube....h?v=IHsuI70SIs8

 

Not so naturalized.

[RushmoreAnts]

I've heard that the species just finds its own niche in an ecosystem, and doesn't harm any native life. And besides- my friend's yard has the highest population density of Tetramorium colonies I've ever seen, yet it also has one of the highest density of native species I've ever seen.

And why not just go ahead and keep them? They're not going to do the environment any harm in a formicarium (and they're not too specialized in escaping, either).
