Proof® is a plant-based bed bug and dust mite spray that kills on contact and vaporizes to penetrate hard-to-reach areas throughout your home. It can be used on sofas, floorboards, furniture, carpets, cracks, and crevices to drive bugs out from where they hide and quickly eliminate infestations. It's approved by the Environmental Protection Agency (EPA Reg. No. 88760-6) and extensively lab tested.
