This product is designed to effectively kill ants indoors or outdoors. The bait inside the traps is very attractive to ants. They get inside the traps and bring the bait back to their nest to feed the colony, which is generally entirely destroyed in 3 to 7 days, including the queen. The special formula in Wilson® AntOut® Ant Traps keeps the bait fresh. Each package includes 3 easy-to-use traps containing 6 grams of bait. Use indoors near ant trails or where ants are seen, and outdoors where ants enter home. For heavy infestations, place traps 1.5 to 3 meters apart.
