Knockout ES Area Treatment

VIRBAC KNOCKOUT Extra Strength Area Treatment with Pyriproxyfen Insect Growth Regulator kills active flea infestations and prevents infestations from developing. Prevents reinfestation for seven months. Adult fleas may be seen in the treated areas when brought in on infested animals or when adults emerge from pupal cases, however a population will not develop in the treated area. In transportation equipment, certain plastics may be whitened or dulled. Apply only to carpets and cloth-upholstered areas, or test an inconspicuous area before treating.

For use in apartments, automobiles, homes, hospitals, hotels, kennels, motels, offices, schools, supermarkets, transportation equipment (buses, boats, ships, trains, trucks), warehouses, utilities, veterinary clinics and other commercial and industrial buildings.

Use VIRBAC KNOCKOUT extra strength Area Treatment at the rate of 16 oz for up to 2100 sq ft (8 oz for up to 1000 sq ft). Carpeted areas may be vacuumed before treatment and after treatment has dried. Treat infested areas or areas which could be infested; these include rugs, carpets, upholstered furniture, pet beds and pet resting areas.

When treating upholstered furniture, treat under cushions and areas where flea development occurs. Cover aquariums and fish bowls and remove birds from area prior to treating.

Notice: VIRBAC KNOCKOUT extra strength Area Treatment has been tested on several types of carpet, fabric and other household furnishings without adverse effects. In a few instances, waxed surfaces have been whitened or dulled. Holding the can 36 inches away from the target surface normally prevents any whitening from occurring.
