Demon WP Insecticide

Demon WP Insecticide, manufactured by Syngenta, is a broad-spectrum insecticide that provides a fast kill and long-lasting residual barrier.

It is a wettable powder made with the powerful active ingredient cypermethrin and comes in packets that dissolve in water. The pre-measured Demon WP Insecticide packets make the mixing process quick and easy without mess.

Demon WP is safe indoors and outdoors for controlling spiders, ants, aphids, chinch bugs, mosquitoes, and more. It is an excellent product for making cracks and crevice applications indoors or broadcasting applications outdoors for up to 60 days of control.

Tools Needed

A backpack sprayer, handheld pump sprayer, or spray rig is required to apply Demon WP Insecticide. We recommend using a handheld pump sprayer for DIY homeowners to make indoor or outdoor applications.

How to Use

• Step 1: Determine how much Demon WP Insecticide to use by measuring the square footage of the treatment area. Find the square footage, measure the treatment areas' length and width in feet, and then multiply them together (length X width = square footage). Demon WP comes in pre-measured packets that can cover 1,000 sq. ft. when mixed with a gallon of water. So, for example, if you have measured a 3,000 sq. ft. area, you will need 3 packets of Demon WP mixed with at least 3 gallons of water.
• Step 2: Before mixing, ensure your gloves are dry, as any moisture that comes into contact with the packets may cause them to dissolve prematurely. In your sprayer, fill the tank with halfway with water. Open the foil packet, take the appropriate amount of water-soluble packets, and drop it in the tank. Let the packets dissolve, and then shake the spray tank. Then add the other half gallon of water and shake the spray tank until thoroughly mixed. Shake the spray tank periodically when making applications to prevent clogging.
• Step 3: Apply a coarse, low-pressure spray to areas where treatment is needed. Use a fan spray when spraying surfaces and vegetation and a pin stream setting when treating cracks and crevices. Reapply every 30 to 60 days, depending on the targeted insect and the severity of the infestation.

Where to Use

Demon WP Insecticide is great for residential, commercial, or industrial areas. When used as a crack and crevice treatment, it should be applied around baseboards, behind cabinets, under appliances, and at the corners of walls. It can also be used as a spot treatment indoors but not as a broadcast application.

For outdoor use, apply Demon WP Insecticide to lawns, ornamental trees, plants, window screens, building perimeters, directly to exterior walls, fire ant mounds, and other areas listed on the label. Do not apply Demon WP Insecticide to golf courses.

When to Use

This product can be used as a preventative treatment and applied to outdoor areas to prevent insects from coming indoors. It can also be used as a spot treatment to kill insects on contact. Depending on the targeted pests or the severity of the infestation, Demon WP Insecticide can be reapplied every 30 to 60 days.

Safety Information

Demon WP Insecticide is safe to use around children and pets when applied according to the product label instructions. Always wear the proper personal protective equipment (PPE) when mixing or applying this product.

Keep people and pets out of treated areas until the spray completely dries.

Special Considerations

Each packet contains 0.3 ounces of Demon WP Insecticide, creating a 0.1% concentration when diluted with 1 gallon of water. Wettable Powders like Demon WP will leave a visible residue as the liquid spray dries.
