Demon WP Insecticide in water-soluble packets is a professional-grade, 40% Cypermethrin-based wettable powder designed for broad-spectrum, long-lasting residual control (up to 90 days) of pests like ants, cockroaches, spiders, and scorpions. The pre-measured, 9.5-gram packets dissolve in water (typically 1–2 per gallon) for easy, mess-free application using a pump sprayer.
