The Best Pesticide for Grub Control

Pesticides do not work to kill grubs. The best insecticide to treat lawns that have white grubs, according to Iowa State University Extension, is a product with imidacloprid. Imidacloprid provides long-term control of the white grubs as it is absorbed by the root system and does not wash away, dilute from heavy rains or degrade in hot weather.
