Raid fumigating fogger creates a deep-penetrating fog that flushes bugs out from where they hide and kills them on contact. When activated, it fills the room with a dry, white cloud of fog. The fog stays in the air for 3 hours. No oily residue and a fresh scent. Can be used in kitchens, living areas, garages, attics, basements, and pet areas. 1 unit treats a room of up to 16′ x 20′. 3 pack.
