Zero In Wham Fogger provides a hands-off method for killing both crawling and flying insects (both adult and larvae) on contact. Simply activate a can in an empty room and leave. Use to treat areas up to 4000 cubic feet (20'X25'x8'). Limits a person’s exposure to the product, making it safer than manual spray operations. Won't leave a sticky or oily coating or damage most surfaces. Kills ants, bedbugs, cockroaches, confused flour beetles, crickets, firebrats, fleas, flies, mosquitoes, pill bugs, rice weevils, saw-toothed grain beetles, silverfish, small flying moths, ticks and yellow mealworms.
