BodyGuard (Fly, Flea, Tick & Insect Repellent) 24oz. Trigger Spray Bottle; Black Curicyn’s BodyGuard Fly, Flea, Tick & Insect Repellent Curicyn’s BodyGuard Fly, Flea, Tick & Insect Repellent is 100% non-toxic to humans and all animals. It works principally in its vapor form, as evaporated molecules that the flies, fleas, ticks or insects encounter near or on the animal. It does not require contact with the insect or fly to be effective. The repellent molecules then physically contact olfactory receptors (e.g. on the antennae, palps or feet of the insect), and cause a behavioral change, such as retreating from an area with a high concentration of the repellent vapor. And because it works via the olfactory receptors in the pests, less product is needed on the animal. In fact, Curicyn BodyGuard has been tested by university entomologists and found to be 3X more effective than other leading fly sprays! It comes in a variety of sizes: Fly, Flea, Tick & Insect Repellent 2 oz. Mister Spray Bottle 8 oz. Mister Spray Bottle 24 oz. Adjustable Trigger Spray Bottle 1 gal. Refill Bottle 1.33 gal.
