Granular insecticides are simply insecticides attached to a porous organic material such as ground up clay or corn cob. Each time the granules get wet they release a little of the insecticide providing for an extended release and longer residual life of the product. Using granular insecticides provides you with a number of key benefits. Granules typically last longer outdoors where rain and and sunlight can quickly break down most liquid insecticides. Also there is no mixing required. The product is already at the optimum strength to get the job done. In addition granular formulations will release the insecticide in the soil more so than on the grass, making your lawn much safer for people and pets. Feel free to call us if you have any questions.
