Fire ant killer. Contains the fermentation-based active ingredient Spinosad which is derived from a soil organism. Also contains a bait that attracts foraging fire ants, and is readily taken back into the nest as food for the colony. The active ingredient in the bait is distributed throughout the colony, killing the ants, including the queen. Fire ants that consume the bait will appear sick and lethargic within 12 to 24 hours. Dead ants will frequently be seen near mounds 24 to 36 hours after application.
