Fireback’s double-strike applicator delivers the flexibility to target the pests you can see and destroy the pests hiding in cracks and crevices. The permanently attached, hinged flip-up straw reaches labeled pests hiding in cracks and crevices. Flip the straw back down to expose the opening for a normal spray. In addition to bed bugs, Fireback’s active ingredients are also ideal for cockroaches and ants. It can be used against 26 additional listed flying and crawling pests, including house flies, mosquitoes, crickets, scorpions, spiders and millipedes. Use Fireback indoors and outdoors to kills on contact and leave a three-month residual.
