Grubs are the immature larvae of beetles that live under your lawn. They obtain nutrients by feeding on the roots of grass, which can cause the grass to die or create damaged turf. Grubs can be a self-sustaining problem, as the larvae mature into beetles. These beetles will go on to lay their eggs in your lawn’s soil, and create an even bigger population of grubs. If your grass is wilting, looks unhealthy, or is starting to turn brown, you may have a grub problem. Look for an unhealthy patch of grass that is brown, or feel around for where the ground is soft and spongy. With a spade or shovel, pull up a small section of sod and see if there are grubs hiding in the soil. These little insects are white and c-shaped. If you have a large number of them in a small area, they are likely causing major damage to your lawn. If you have an active grub problem Residential Lawn Pros will treat the turf in early Spring and will protect your lawn throughout the entire growing season.
