Product Overview Extinguish Professional Fire Ant Bait combines (S)-Methoprene, an Insect Growth Regulator (IGR), with attractive bait that foraging fire ant workers take back to the queen. (S)-Methoprene adversely affects the queen's ability to reproduce, so when existing workers die (normally within a three-week period), no new workers are created to replace them. The result? Starvation and elimination of the entire colony. TIPS: Extinguish Fire Ant Bait can take 8 to 12 weeks to see results, however, you should only apply this if the soil temperature is about 65 degrees, it is not going to rain within 8 hours, and the fire ants are foraging. It is recommended to broadcast the treatment instead of mound treat for best results, and you should apply the product where the ground is in the sun, since this is where fire ants will nest.
