We've got a lot of ants & ant varieties here, but the 1 that doesn't even belong here is a bad one, European Fire Ants. Good luck trying to get rid of them, no one has ever successfully done so. You might be able to reduce the numbers but they're never totally gone. They've been battling them in Maine & Canada for nearly 100 yrs. I did get some Antixx, which is Spinosad based pellets, the ants carry back to their tunnels. Nope, these jerks do not create mounds, they have tunnels, 15 feet deep, all over several acres, so you can't tell exactly where home base is, pIus they've got multiple queens spread out. They like moisture, trees, shade, mulch, rocks...what a PITA...like it's all gravel roads back here! So at any given moment, spring, summer & fall, you can see them running around, looking for food or stinging somebody trying to dig & garden...that somebody is often me.Those ants. Ants are ants in some aspects. Put some boric acid down around the house, that should keep them out and is harmless too the cluckers. or mix Boric Acid and DE and puff dust in and out. If you want throw some powdered sugar in it to entice them to it to make sure they get it.

When using Antixx, the yellow bait pellets are immediately seized upon & carried off. I once followed the "carry bait trail" to see where they went. Some submerged with bait into various holes along a large area, but I trailed a few ants nearly 3 acres! Ugh, nasty buggers.
