Temprid FX Insecticide is a multi-purpose suspension concentrate insecticide that can be used both indoors and outside. The FX stands for ‘flexibility’ because Temprid FX can be used on a large variety of insects in many settings. Combining the fast-acting power of beta-cyfluthrin and the transferal power of imidacloprid, Temprid FX can be used to combat ants, bed bugs, cockroaches, flies, spiders, and more. Target treat your home in places where pests have been spotted or give the outside of your home a perimeter spray (3 feet up and 3 feet out around the foundation of the home) to prevent future infestations.
