Increased Scrutiny of Flea and Tick Control Products for Pets

The U.S. Environmental Protection Agency is intensifying its evaluation of spot-on pesticide products for flea and tick control due to recent increases in the number of reported adverse reactions in pets treated with these products. Adverse reactions reported range from mild effects such as skin irritation to more serious effects such as seizures and, in some cases, death of the pet.

Flea and tick products can be appropriate treatments for protecting your pets and your family’s health because fleas and ticks can transmit disease. While many people use the products with no harm to their pets, EPA recommends that pet owners take precautions when using these products. People should carefully follow label directions and monitor their pets for any signs of an adverse reaction after application, particularly when using these products for the first time. Also, before use of these products on weak, aged, medicated, sick, pregnant or nursing pets, or on pets that have previously shown signs of sensitivity to pesticide products, EPA recommends that a veterinarian be consulted. Additional safety tips are available for taking care of fleas and ticks on your pet.

Pets may experience adverse reactions from flea and tick control products, including spot-on treatments, sprays, collars and shampoos. However, the majority of reports to EPA are related to flea and tick treatments with EPA-registered spot-on products. Spot-on products are generally sold in tubes or vials and are applied to one or more localized areas on the body of the pet, such as in between the shoulders or in a stripe along the back.
