Activyl for Dogs

Fleas are a perennial problem in pets. Proper sanitary measures can reduce the prevalence of flea infestation, but these annoying pests manage to recur in spite of precautions. Flea eggs and larvae are more of a problem than adult fleas.  It needs a lethal remedy to fight this menace and various topical spot-on solutions available are just the right thing to do.

Activyl for Dogs is one such product from Merck that addresses the flea problem. A one-time application every month provides complete protection against adult fleas, its larvae and eggs, effectively preventing flea reinfestations.

Activyl - How it works?

The active ingredient Indoxacarb in Activyl acts using a process that reacts with flea’s own enzymes. Slowly but gradually the solution spreads through the pet’s skin. As soon as the flea bites the dog, it absorbs Indoxacarb, which when reaching the flea’s gut, changes the enzymes. This is what is called bioactivation. The flea dies due to the paralyzing effect of the ingredient.
