We use amdro or generic types of fire ant bait, to keep em out of the yard basically. Have to continually treat.
Recently tried Permethrin mixed with water and it seemed to be even better.
The drought here, did not kill them, only sent them really deep. As it has become a bit wet they've come back with a vengence it seems.
I have not tried talstar though, but have not seen the need as what Carolyn brings back from the store labeled for fire ants and or permethrin has been working fine so far.
Not sure I'd like crazy ants honestly, they are not that far from us, but having camped where they are I can deal more easily with fire ants personally.
