Dr. Mercola Flea and Tick Defense Spray

A Repellent to Help Protect Your Pets from Fleas, Ticks, Mosquitoes, and Flies Fleas, ticks and mosquitoes are more than an itchy nuisance – they can carry and transmit potentially harmful bacteria, viruses and even tapeworms to your cat or dog. The traditional veterinarian industry’s answer to the growing flea and tick crisis is to use harsh chemical-laden products. These products can contain one or more potentially hazardous ingredients, including proven neurotoxins and one officially classified as a “Group C – Possible Human Carcinogen.” The ingredients in regular flea and tick repellent products can work their way to your pet’s bloodstream and organs, sometimes within minutes of application.

Our flagship pet pest repellent product, Flea & Tick Defense, provides a worry-free alternative that doesn’t rely on harsh, potentially hazardous chemicals.
