Wilson AntOut Ant Traps are designed to effectively kill ants indoors or outdoors. The bait inside the traps is highly attractive to ants. Ants get inside the traps and bring the bait back to their nest to feed the colony, which is usually destroyed in 7 to 10 days, including the queen. The special formula keeps the bait permanently fresh in traps. Clean and easy to use. Includes 3 traps.
