Dudley - how ironic that you should ask.

DuPont just introduced a new fireant control product in September. ADVION represents an entirely new class of insecticide (Oxadiazine). The product's active ingredient (indoxacarb) exhibits toxicological characteristics never before achieved. The product (a bait) is virtually non-toxic until the fire ant workers feed it to the larvae. The active-ingredient is then metabolized in the larvae's gut, and is then released throughout the ant colony - killing the entire colony within hours (or 1-2 days tops).

I can assure you - IT WORKS! You can come back to this board and cuss my "girly name" if it doesn't - ha.
