Diatomaceous earth
Little crystals of silica are supposed to scratch the ant's cuticle so they
dehydrate and die. Indeed, if you take a colony of ants and shake them up in
bag with diatomaceous earth, about half die. But when you use it on ants
outside they usually find ways to avoid it so not many ants are killed. They
will not eat it in food and foraging ants do not track it into colonies
where it might kill the queen or young fire ants.

I wish DE worked! I swell up terribly from just one fire ant bite. I once
resembled Quasimodo, thanks to a fire ant that crawled off a shirt in a
clothes closet and bit me on the eyebrow.

Speaking of fire ants....we're getting ready to drop "over and out" on our
new lawn (moved recently) and have been fighting scorpions as well (new
construction) . I have heard that diatomaceous earth around the perimeter
of the home with deal a blow to scorpions other arachnids and insects and
a friend recently told me she uses DE to fight fireants.

Anyone here used/had success with DE for fireants? Seems like it would be
non-toxic solution if it does....

cheers!
