KNOCKOUT® Brand Products

Don't just treat the pet, treat the whole environment.

KNOCKOUT® E.S. Area Treatment, KNOCKOUT® Room and Area Fogger and KNOCKOUT® Area Treatment can help treat and control fleas and ticks around the home.  The Companion Animal Parasite Council (CAPC) recommends that all dogs be treated year-round with flea control products to limit infestations on the pet and prevent establishment of flea populations in the home. If a flea infestation is established in the home it may take several months to bring it under control. Flea infestations are a public health concern as people in infested environments are often bitten by newly emerging fleas. Many products only kill adult fleas, leaving 95% of the population alive in the house.  KNOCKOUT Brand Products have a family of products that kills adult fleas, kills pre-adult fleas, kills ticks and aids the prevention of flea re-infestation.

KNOCKOUT® Room and Area Fogger

(Pyriproxyfen 0.10%, Pyrethrins 0.05%, n-Octyl bicycloheptene dicarboximide 0.40%, Permethrin 0.40%)

EPA Reg. No. 2382-184

KNOCKOUT® Room and Area Fogger contains a combination of three insecticides that stops the flea life cycle in three ways and controls other insects. The first insecticide is pyriproxyfen (NYLAR® Insect Growth Regulator), that will not allow the flea to reproduce, thereby providing long-term control. The second insecticide is the botanical, Pyrethrin, which provides effective quick kill of insects upon direct contact and an added benefit of flushing the insects from their hiding place to aid in a more complete control. Permethrin, the third active insecticide, provides activity until the NYLAR Insect Growth Regulator takes effect. KNOCKOUT Room and Area Fogger contains a combination of ingredients that kills both adult and hatching fleas. NYLAR Insect Growth Regulator continues to kill hatching fleas for 7 months by preventing their development into adults. The fogger reaches fleas (and other insects) hidden in carpets, rugs, draperies, upholstery, pet bedding, floor cracks and open cabinets. Occasionally, adult fleas may be present in treated areas when reintroduced from infested animals.
