Source Kill MAX Ant Killing Bait, 0.21 oz, 6/Box 12 Boxes/Carton

Contains a powerful insecticide, Fipronil, which gets rid of ants commonly found in households. Ants are attracted to the bait and then carry it back to their colony to destroy the queen and entire colony. These easy-to-use, no-mess, child-resistant ant baits need no activation. Just place them where you have seen ants and they will work day and night to control the problem killing ants at the source. Can use in multiple locations at the same time.
