About this item
Product details
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 "Tools and Sprayers" section). Demon WP is for crack and crevice or spot treatment for residual and contact pest control in, on and around buildings and structures and their immediate surroundings and on modes of transport. Permitted areas of use include, but are not limited to, industrial buildings, houses, apartment buildings, laboratories, buses, greenhouses and the nonfood/feed areas of stores, warehouses, vessels, railcars, trucks, trailers, aircraft (cargo and noncabin areas only), schools, nursing homes, hospitals (non-patient areas), restaurants, hotels and food manufacturing, processing and servicing establishments. Demon WP Authorized by the USDA for use in inedible product areas in Federally inspected meat, poultry and egg processing plants. 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. Always read the label before use. Must be used according to the label!!
