Easy Use

Before using Demon WP, the infestation species and level of infestation should be determined. Each envelope contains four water soluble packets of Demon WP. Mix one or two packets per gallon of water to create a finished solution. Use a crack and crevice spray system or spot treat known locations of infestations of insects. Thoroughly treat all cracks and crevices for effective control of most insect species. Treat outdoors and indoors in non-food handling locations. The spray can be used on both porous and non porous surfaces. Only treat completely dry surfaces to prevent runoff. It may leave a white residue on dark backgrounds. Any unwanted build-up is easily removed with soap and water.

How it Works

Demon WP is a wettable powder pesticide containing 40 percent of the active ingredient cypermethrin. This is a man-made version of a naturally occurring plant toxin found in chrysanthemum flowers. This scientifically created pesticide takes the insect repellent effects of the natural toxin and improves its effectiveness and lengthens its effective life span. Cypermethrin is a second generation pesticide. It kills insects by disrupting their nervous systems, causing muscles spasms, eventual paralysis and a quick death. Demon WP is effective through insect contact and ingestion.

Demon WP is Proven Effective Against:

German cockroaches, with a 25 minute knock-down time-frame. American cockroaches, Oriental cockroaches, Brown Banded cockroaches, Smoky brown cockroac, all with similar results.

Ants, Millipedes, Centipedes, Sod Web Worms, many Spiders, Scorpions, all types of Flies, Hornets, Wasps, Bees, Pillbugs, Sow bugs, Crickets, Silverfish, and Firebrats.


Do not use near food. Do not use or allow near any aquariums or ornamental ponds containing fish. Wet powder or finished solution skin contact may cause reddening and temporary tingling. Wash any contaminated clothing before wearing them. Only use equipment in god repair to apply product.


 1 foil package containing 4 water soluble packets each with 9.5 grams of 40% cypermethrin.
