Activyl Dog 20-40kg Large Purple 6's Flea Treatment (A2780)

Activyl is also effective in killing developing stages of fleas in the pet's immediate surroundings and may also be used as part of a treatment strategy for flea allergy dermatitis (FAD).
Fleas can quickly become a significant problem for dogs and cats and the rest of the family. Since each female flea can produce 40 to 50 eggs or more a day, even just a few fleas can infest your entire home in a matter of days.
Apply Activyl monthly to break the flea life cycle. This:
- Ensures that the fleas that jump onto your pet will soon stop feeding, be paralysed and die
- Kills eggs and larvae in the environment and prevents reinfestation
- Helps in the management of pets that develop itchy skin (flea allergy dermatitis or FAD) due to flea bites
Activyl is an innovation in monthly spot-on flea treatment and prevention that works differently from conventional flea treatment as it only becomes fully active on contact with flea enzymes.
It's also quick-drying, fragrance-free, water fast on dogs.
Controls existing flea infestations and provides control of new infestations for at least 4 weeks
