How Demon WP Insecticide Works

Demon WP is a residual insecticide concentrate with the active ingredient Cypermethrin. Cypermethrin is in the synthetic pyrethroid class of insecticides. It is a man-made active ingredient that attacks the central nervous system of insects that come in contact with or ingest it. Demon WP is diluted with water and applied with a gallon pump sprayer. After it dries, Demon WP continues to work for up to 3 months.

Target Uses of Demon WP

Demon WP (Water-soluble Packets) Insecticide is for crack and crevice and/or spot applications for residual and contact control of Ants, Carpenter Ants, Cockroaches, Crickets, Spiders and certain other insect pests. The Demon WP water-soluble packets make mixing and use very easy when used with a 1 gallon compressed air sprayer. (See our selection of sprayers in our Sprayers section).

Demon WP (Wettable Powder) is excellent for larger, tougher pests such as cockroaches, spiders, scorpions, or stink bugs because there is a high concentration of active ingredient. Demon WP is labeled for a wide variety of pests, however, making it an extremely popular general use insecticide for perimeter treatments outdoors or crack and crevice treatments indoors.

The wettable powder formulation also makes Demon WP ideal for porous surfaces such as concrete since the individual particles of active ingredient are larger and can more easily stay on top of the surface.

Demon WP leaves a white powdery film that may be visible on darker surfaces. For applications where this is a concern, consider using a liquid concentrate instead.

Demon WP Insecticide Application Instructions

Each foil envelope of Demon WP Insecticide in Water-Soluble Packets contains four water-soluble packets of Demon wettable powder (WP). The foil envelope must be opened for use. Because water-soluble packets readily dissolve in the presence of moisture, do not allow them to get wet before adding to the applicator tank.

Wear dry gloves when handling the water-soluble packets. Handle with care because excessive handling may cause rupture of the water-soluble packet. Unused water-soluble packets should be stored in the original foil envelope, folded over to minimize exposure to moisture.

Demon WP Insecticide in Water-Soluble Packets are intended for dilution with water for applications. For best results, dilution should be achieved if the following steps are taken:

1. Fill applicator tank 1/2 with water.
2. Add desired Demon WP Insecticide in Water-Soluble Packet(s).
3. Allow 1-2 minutes for dissolution of water-soluble packet(s).
4. Agitate, stir or shake applicator tank.
5. Finish filling applicator tank and agitate again before use to ensure satisfactory suspension.

Note:
• Upon standing without agitation for more than 1 hr., the applicator tank should be agitated, stirred or shaken again to achieve satisfactory suspension.
• Make up only amount of application volume as required.
• This product should not be applied with oil.

Tank Mixing
Demon WP in Water-Soluble Packets may be tank mixed with other currently registered pesticides unless expressly prohibited by the product label. A small volume mixing test with the other products is recommended to ensure compatibility. Observe all restrictions and precautions which appear on the labels of these products.

Pay particular attention to cracks and crevices; also see Outdoor Surface Use on the product label.

Outdoors-

See above for complete mixing instructions.

For Perimeter Barrier Treatments

To help prevent infestation of buildings, apply to a band of soil and vegetation 6-10 ft. wide around and adjacent to the building. Also, treat the building foundation to a height of 2-3 ft. where pests are active and may find entrance. Apply as a coarse spray treatment to thoroughly and uniformly wet the foundation and/or band area, using 1-5 gals. of treatment solution applied to 800-1600 sq. ft.

Outdoor Surfaces

Apply with either hand-held or power application equipment as a residual spray to surfaces of buildings, porches, screens, window frames, eaves, patios, lawns, refuse dumps, garages and other similar areas where these pests are found. Also, may be used as a spot treatment in applications to lawns in landscaped areas in and around residential, commercial, institutional and industrial buildings, and similar areas where these insect pests are active.

Fire Ants (Mounds)

For individual fire ant mounds, apply Demon WP as a drench. Gently sprinkle a total of one gallon over the surface of mounds up to 12 inches in diameter. Use 2 gallons for larger mounds. Thoroughly wet mound and surrounding area. Treat new mounds as they appear. Pressurized sprays may disturb the ants and cause migration. If possible, applications should be made on warm days after recent rainfall. All colonies in the vicinity should be treated, including those that have not yet constructed a mound.

Scorpions

Treat and remove accumulations of lumber, firewood and other materials that serve as harborage sites. Apply as a coarse spray treatment to the point of drip.

*Demon WP is not appropriate for applications using a hose-end sprayer.

*See product label for complete outdoor application instructions.
