This weatherized granular perimeter bait is used outdoors or indoors to kill and control cockroaches, ants, crickets, silverfish and carpenter ants. Niban's weatherized granules don't degrade from heat or sunlight and will last through four inches of rain. Niban is the one bait that will continue to work because Niban has no known resistance and is virtually odorless.

Niban kills the microoganisms in the insect's stomach and blocks enzyme production causing starvation. And since it affects none of the insect's major systems, they can't develop resistance.
