  • Activyl Flea Control for Dogs

    Activyl for Dogs is a highly effective and safe new product from Merck containing the active ingredient indoxacarb, which not only eliminates adult fleas on dogs but also disrupts the flea’s lifecycle by preventing eggs and larvae developing further. Activyl is an ectoparasiticide, which needs to be applied once a month only for total flea control.

    Activyl contains Indoxacarb, an active ingredient with an innovative mode of action for flea control. The medicine acts by blocking the nerve sodium channels of fleas. After application of Activyl, its active ingredient spreads through the skin of the dog. When a flea bites the dog, it triggers bioactivation by which the active ingredient is activated using enzymes inside the flea.

No more bugs!

The dogs have not had a single bug on them and that's quite amazing given where I live near the woods.
