Fire Ant Bait gives excellent control of red imported fire ants and big headed ants when applies according to the label. Fire Ant Bait has little to no impact on non-target insect species. The bait is attractive specifically to fire ants, and not to other insects or animals. The queen then stops laying viable eggs and ant larvae can not complete development. As a result, no new workers are produced and existing workers and the queen die from starvation or old age.
Fire ants are extremely attracted to soybean oil and use it as a food source for ants in the colony.
The active ingredient in the bait, pyriproxyfen, is not repellant to them. Fire Ant Bait is labeled for application in any outdoor area where ants are likely to be foraging. Fire Ant Bait should be applied only when ants are actively foraging. Spring and fall applications are generally most effective. Wait a minimum of 36 hours after application.
