KNOCKOUT™ Area Treatment

It is very frustrating trying to rid fleas from my home.  What other factors should I consider to successfully kill fleas?

None of the ingredients in KNOCKOUT™ Area Treatment affect the pupae life stage of the flea life cycle.  Adult fleas may be observed 2-4 weeks after the initial treatment since fleas previously in the protected pupae are hatching and emerging. Pyriproxyfen, an ingredient in this flea spray, continues to kill fleas for 120 days (4 months) by preventing their development into the adult biting stage. It reaches fleas hidden in carpets, rugs, drapes, upholstery, pet bedding, and floor cracks. It prevents reinfestation and buildup of fleas in the home.

How do I apply KNOCKOUTTM Area Treatment?

SHAKE WELL BEFORE EACH USE. Hold can 2 or 3 feet from surfaces to be treated. Be sure to apply uniformly using a sweeping motion to carpets, rugs, drapes, and all surfaces of upholstered furniture. Be sure to treat pet bedding as this is a primary hiding place for fleas. No need to remove pet bedding after treatment. DO NOT TREAT PETS. Use a registered flea control product on your pets in conjunction with this treatment.  Repeat as necessary. Avoid wetting furniture and carpeting. A fine mist or spray applied uniformly is all that is necessary to kill fleas and ticks.
