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.

  • Starts action within 8 hours and keeps on killing fleas for 4 weeks
  • Safe for puppies 8 weeks and older and weighing 4 lbs and above
  • Odor-free, quick drying and waterproof
  • Not only acts against adult fleas but also breaks flea lifecycle and prevents eggs developing into larvae


Hold the applicator in upright position away from your face and snap open its tip by folding it. Keep the dog in standing position. Part the coat between the shoulder blades and squeeze entire contents of the applicator onto the skin evenly. Do not allow product to overspill. For very small and small dogs, apply at one spot. For medium, large and very large dogs, apply at two, three and four spots respectively along the shoulder blade. Repeat every 30 days.


  • Do not use on puppies and dogs under 8 weeks of age and weighing less than 4 lbs.
  • Do not use on pregnant or lactating bitches. Consult your vet before using on ageing or wounded dogs.
  • Do not use more than one applicator per month.
  • Avoid contact with skin or eyes. In case of accidental splash, rinse the affected area thoroughly and contact a nearby poison control centre. If swallowed, drink a glass or two of water and call a doctor.
