Grubs are actually the larval stage of a variety of different kinds of beetles, including May and June bugs and voracious Japanese beetles. Adult beetles lay their eggs in the soil in mid to late summer. As the eggs hatch, they develop into the white-wormish looking larvae. As the larvae grow, they work their way down to the root zone of your lawn where they eat the roots. In August or September, you may suddenly notice brown or dead areas of grass in your lawn that can be rolled up like a carpet. Once damage is visible, the use of a contact control product is necessary to kill the grubs and minimize damage. Grub control may need to be included as part of your lawn maintenance program. Controlling grubs most effectively is largely a matter of timing. If you have a prior history of grubs, or a susceptible variety of grass, consider our grub control for season long protection.
