Colony killing fire ant killer. This product is a bait so you will initially see more ants. The active ingredient will kill the worker ants slowly so they have time to take the bait back to the Queen and kill the colony. Decreased ant activity will be observed as soon as 24 hours after bait placement. Fire ant mound control will occur in as little as 48 hours after application. Pets and children can re-enter treated area immediately after application. No watering necessary.
