adult grubs - Grubbing


When the soil warms up again in the spring, the large, mature grubs move back into the upper soil levels, where they transform into adult beetles that emerge in early summer and start the whole process over again. The key to controlling grubs is to kill them before they hatch and begin to . Lawn grubs are the wriggly, worm-like larvae of different types of beetles, like Japanese Beetles and June Bugs, that hatch in the spring and summer. These pests are roughly an inch long, curl up into a C-shape when disturbed, burrow into your lawn, and feed on your grassroots.

Adult beetles lay eggs in the soil; the eggs grow into larvae (grubs). Depending on the species the grubs may feed in the soil for a year or more. The most effective timing of insecticides is when the larvae are young and near the surface of the soil. This is typically in summer and fall. Adult grubs lay eggs in the soil during the summer. Once the grubs hatch, they feed on plant roots and descend deep into the soil once it becomes colder, to spend the winter there. In the spring, grub worms return to the surface and keep feeding on the roots until they become ripe. The biggest damage is caused from mid-September to November or.

Signs of a Grub Problem Raccoons, skunks, armadillos, or birds dig up your yard searching for large, mature grubs to dine on. The dead patches of grass in your lawn peel back like pieces of loose carpet because the grubs have eaten the roots that usually hold the turf in place. The grubs we turn over in the spring garden are essentially in hibernation. They remain in a non-feeding state until May, when they undergo pupation before emerging from the ground as an adult in June and July. As alarming as these juicy springtime grubs appear, they do little harm to plants in the spring.

The grubs get their start when the adult beetles lay eggs in your turf, usually in spring. After the eggs hatch, the grubs evolve in three stages, with grub damage greatest in late summer, when you will see areas of your lawn thinning and yellowing. Later, irregular brown patches appear in your turf. The beetles typically lay their eggs during mid summer in sunny areas of the lawn. Their larva (lawn grubs) live in the soil eating on the roots of grass and other organic matter leaving it dry, brown and dead. Eventually grubs turn into adult beetles and come out of the soil to mate and lay eggs which hatch into more grubs. Was This the Culprit?

Not necessarily, because the adult stage of grubs are flying beetles that can travel to your garden from outside your property. Learn more about these beetles.

Sometimes the best way to get rid of lawn grubs is to keep them out of your soil in the first place. That means targeting the adult beetles before they have a chance to lay their eggs. When they are in their adult beetle form, they are dealt with just like any other above-ground garden bugs. Usually, a standard insecticide will work.
