Raid Ant Baits kills ants you see and the ants you don't see. Ants are attracted to the bait, eat the bait and return to nesting area to die. The bait carried back to the nest is shared and continues to kill other ants for up to 3 months. Use Raid Ant Baits indoors near entry points to kill ants where they hide. Raid Ant Baits may be placed in locations such as closets, basements, attics, recreation rooms, living areas, kitchens, bathrooms, dining rooms and pantries. For maximum effectiveness, place all baits at the same time. Avoid placing baits directly on top of surfaces treated with a Raid spray product to make sure ants can bring the bait back to where they hide.
