I was unaware that Phorid flies ate fire ants...

There is a species that is parasitic on fire ants exclusively. When in
balance, the ants are controlled because as soon as a fly appears,
they dive underground. So their foraging is limited.

Ah! Cool. I'll have to look for that.
I've had good luck with beneficial nematodes. They are more effective
against fleas than fire ants, but I'm not having to fight them as hard
as I used to. Of course, whenever any appear, I keep Amdro on hand. g



Do poison baits work on them?

Good question. I do not know. The colonies do have multiple queens, so
that would make targeted baits less effective.

Not if, like Amdro and fire ants, they feed the bait to the queens.
Then there is Logic, a sterilant.
