Demon WP Insecticide

Demon WP Insecticide is manufactured by Syngenta and 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 the mess.

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

Tools Needed

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

How to Use

• Step 1: Measure the treatment area (length x width) to determine how much Demon WP you will need. Demon WP comes in pre-measured packets which 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, be sure that your gloves are dry as any moisture that comes into contact with the packets may cause them to prematurely dissolve. In your sprayer, fill the tank with halfway with water. Open the foil packet and take the appropriate amount of water-soluble packets and drop it in the tank. Let the packets dissolve (about one to two minutes), and then shake the spray tank. Then add the other 1/2 gallon of water and shake the spray tank again until thoroughly mixed. Shake the spray tank periodically when making applications to prevent clogging.
• Step 3: Apply as a coarse, low-pressure spray to areas where treatment is needed. Apply as 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, apply it around baseboards, behind cabinets, under appliances, corners of walls. It can be used as a spot treatment indoors as well, 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

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

Safety Information

Demon WP Insecticide is safe to use around children and pets when applied according to the label and mixing instructions. Allow treated areas to ventilate or dry before entering. Always wear the proper personal protective equipment (PPE) when mixing or applying Demon WP.

Special Considerations

Each packet contains 0.3 ounces of Demon WP Insecticide, which will create 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.
