Buzz Off is not a systemic insecticide that penetrates the skin and works from the inside out. Instead, it uses the horse's natural oils and skin movements to coat the animal and provide protection. Because of the potency of this product, its label warns against humans getting the product on their skin or inhaling it over a prolonged period.

Boehringer Ingelheim has introduced a pour-on insecticide available only through your veterinarian, writes editor Kimberly S. Graetz in the September edition of The Horse. Called Buzz Off, this insecticide is touted as controlling horn, stable, deer, and horse flies at a fairly high rate for up to two or more weeks with one application, based on efficacy control information. (High-density insect areas will require more frequent applications.) Buzz Off also works on lice and ticks, and aids in control of mosquitoes and black flies. Buzz Off can be used as a premises spray with a mist sprayer, and also can be sprayed on horses or used as a wipe on. The active ingredient of Buzz Off is permethrin. After the oil-based product is poured onto the horse's topline (avoiding the face and eyes), it spreads protection across the body, even to the face and legs, over a period of about 24 hours.
