Activyl [Single Dose] Spot-on Once-a-month Topical Flea Treatment for Dogs 44 - 88 Lbs
Activyl is a topical ectoparasiticide containing the pro-insecticide indoxacarb. It is the only flea treatment to benefit from metabolic activation (bioactivation). Activyl is metabolised to its highly active form by flea enzymes following contact or (primarily) ingestion. This technology has benefits beyond pest control, minimising unnecessary chemical exposure to the pet, their family and household.
