Residual insecticidal flea and tick spray for dogs that contains 2% permethrin and 0.05% pyriproxyfen (Nylar®) insect growth regulator to sterilize fleas and their eggs for 3 months. LONG-ACTING KNOCKOUT kills adult fleas for up to 60 days, ticks for 30 days, while the IGR prevents flea re-infestation. Do not use on cats.

Benefit:

Perfect for owners that do not like to use spot-on treatments. More economical than spot-ons for flea and tick protection. One bottle is sufficient for four applications at a two month interval to an average 30-35 lb. dog.

Use:

Use only on dogs 12 weeks and older. Spray over entire haircoat making sure the coat is thoroughly wetted to the skin. Spray against the lay of the hair, ruffling the coat on long-haired dogs. Weight of dog, length of hair and density of coat will determine amount of spray applied to wet the skin (average dose approximately 7.5g/kg). Do not towel dry.


Do not use Virbac® Long-Acting Knockout Spray on cats.
