Raid Concentrated Deep Reach Fogger kills a broad range of insects. Designed for serious insect problems. Continues exterminating for up to two months. One fogger covers up to 5,000 cubic feet. No worries with a non-staining formula that leaves no wet messy residue. Penetrates into cracks, crevices and carpet fibers to seek out roaches and fleas, and kill bugs where they live, breed and hide.
