Flea Control Spray for Dogs and Cats

Frontline Spray is a topical tick and flea treatment for dogs and cats. Frontline pet meds end the flea life cycle by killing adult fleas before they can lay eggs. Fipronil, the active ingredient in Frontline Spray, is a GABA inhibitor and broad-spectrum insecticide that disrupts the central nervous system of fleas and other insects. Available in quantities of 250 mL and 500 mL.

Frontline Spray eliminates flea infestations by killing adult fleas before they can lay more eggs. This effectively breaks the flea life cycle to stop infestations and prevent new infestations from occurring. Frontline Spray also controls ticks for up to one month and eliminates chewing lice infestations.
