How does Knockout work?:

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 Nylar, an 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 effect 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 takes effect.

How to use Knockout fogger:

Read entire label before each use.
Use one fogger per every 6,000 cubic feet of unobstructed area.  Use additonal units for remote rooms or where the free flow of fog is not assured.

Please read the room preparations as outlined on the Knockout Fogger can.

To start fogging:

Shake fogger well before using.  Hold can at arms length with  top of can pointing away from face and eyes.  Push down on finger pad until it locks.  This will start fogging action.  Set canister in an upright position on a table, stand etc., and place several thicknesses of newspaper under the canister to prevent marring of the surface.  Treat the whole dwelling, using multiples units.  Leave the building at once.  Do not re enter the building for 2 hours.  After two hours open all outside doors and windows, turn on air conditioner and/or fans and let treated area air for 30 minutes before re occupying.

For use only when building has been vacated by human beings and pets. Ventilate treatment area for 30 minutes before re-entry. For best results treat all infested areas.
DO NOT use more than one fogger per room. DO NOT use in small, enclosed spaces such as closets, cabinets, or under counters or tables. DO NOT use in a room of 5 ft. x 5 ft. or smaller instead allow fog to enter from other rooms. Turn off ALL ignition sources such as pilot lights shut off gas valves, other open flames or running electrical appliances that cycle off and on i.e. refrigerators, thermostats, etc.. Call your gas utility or management company if you need assistance with your pilot lights.
Harmful to humans, if swallowed, avoid breathing vapors or spray mist.  Avoid contact with eyes, skin or clothing. Avoid contamination of food.
