Quickly control cockroaches, spiders, and over 20 other pests in and around your home with Demon WP. This long-lasting residual insecticide is a favorite among pest control professionals because it is easy to apply and long-lasting.

Demon WP is a versatile insecticide that can be used both indoors and outside to control pests. The active ingredient, cypermethrin, is known for its speed and strength when controlling various insects.

The WP in Demon WP stands for wettable powder. When the solution dries, a fine powder is left behind. When insects crawl through an area that has been sprayed with Demon WP, they are more likely to pick up this powder and carry it with them, ensuring a lethal dose of active ingredient. It also has a long-lasting residual which means reapplying less often than other insecticides, saving you both time and money.

Demon WP is particularly helpful when cleaning out large infestations of cockroaches and spiders. Ants, aphids, stink bugs, Asian lady beetles, boxelder bugs, scorpions, mosquitoes, and wasps can also be controlled by Demon WP.

Demon WP comes in convenient water-soluble packets. These small packets can be dropped directly into a sprayer containing water, eliminating the need to measure the insecticide. Demon WP is packaged with 4 water-soluble packets within a larger foil envelope. Open the foil envelope to remove the number of water-soluble packets needed.

Consult the label to decide if you need 1 or 2 pre-measured packets for your treatment. The number of packets required depends on the pest you are trying to control. The chart on the product label will help you determine how many packets are needed.

To create your mixture, fill your sprayer with half a gallon of water. Add the packets of Demon WP directly to the sprayer, fill the sprayer with another half-gallon of water, replace the cap, and shake to mix your solution. The packets will dissolve into a suspension that should not clog your sprayer if the solution is quickly shaken. If you notice any clogging, simply shake or agitate your solution to suspend the Demon WP again.

Outdoors, spray on and around the perimeter of buildings up to 3 feet up and 3 feet out. The insecticide can also be sprayed on the eaves and soffits of a house, and around door and window frames. You can also apply to shrubs and ornamental trees and plants. Lawns can also be sprayed to control ants, spiders, mosquitoes, and more.

Indoors, Demon WP can be used in residential and commercial buildings in non-food handling areas. Spray in cracks and crevices including the corners of rooms, around door and window frames, where baseboards meet the floor, and where plumbing pipes and utilities enter the home. 

Use all of your mixture within 24 hours or safely dispose of the remaining mixture. Do not store pre-mixed Demon WP. Demon WP dries white and can possibly stain dark surfaces. Test an inconspicuous area first if you are worried about staining.

Demon WP will last up to 4 weeks outside and 12 weeks indoors. Read the Demon WP label to determine how often the insecticide will need to be reapplied.
