Hartz® UltraGuard Pro® Flea & Tick Treatment
Active Ingredient – Adulticide
Etofenprox is the adulticide active ingredient found in Hartz® UltraGuard Pro® Flea & Tick Treatment for Dogs and Cats. The mode of action for etofenprox is similar to traditional pyrethroids. Etofenprox blocks closure of the sodium channels in neurons in the parasite’s nervous system, resulting in excitation. Excitation of the parasite’s nervous system brings about death. Etofenprox is quite different though from traditional pyrethroids in chemical structure and in toxicity profile. The ether unit in the structure of etofenprox, versus the ester unit commonly found in traditional pyrethroids, is what differentiates the active and determines its high margin of safety for warm-blooded animals. With low acute oral and dermal toxicity in mammals, etofenprox provides a safe and effective topical active to control fleas, ticks and mosquitoes on dogs and cats.
The adulticide active ingredient in Hartz® UltraGuard Pro® Flea & Tick Treatment for Dogs and Cats, starts killing fleas within 15 minutes.
