Activyl is once-a-month spot on application for treating fleas, flea larvae and flea eggs found on dogs.

  • RaymondBetter flea product

    I have used multiple flea products on my pet but it is only Activyl that works perfectly.

  • JoshuaBest treatment

    best treatment

  • JamesWorks great

    Good results, no side effects and works great!

  • MeganGet this stuff!

    I was using Advantage for the past 2 years to help cure my dog’s flea infestation but it didn’t seem to work anymore. Maybe the fleas got immune. Then my vet recommended using Activyl and it showed very promising results. My dog was itch free within 3 hours of administration. Effective formulation!
