How to Know If You Have Grubs in Your Lawn
White Grubs: A threat to your lawn in Milwaukee, WI
Are you noticing unusual changes in your lawn? If your lawn appears unhealthy, has yellow patches, small holes or a disrupted root system, you may have a white grub infestation. Although small in size, these destructive pests can cause significant, costly damage to local lawns if no control methods are taken.
Symptoms of Grub Activity
White grubs are the small, plump, white larvae of European Chafer, Japanese, and May and June beetles. These c-shaped pests live underground and will attack your lawn by viciously chewing on grass roots.
After grubs destroy a lawn’s root system, grass may appear unhealthy, weak or possibly yellow in patches, as if it is drying out. As your lawn is greening up in the spring, keep an eye out for patches that never turn green as this is a common sign of grub activity. Since the damage done by white grubs is similar to symptoms of drought or dormancy, many homeowners assume their lawn just needs more water to return to its normal green state. Unfortunately, it’s not that easy.
Other symptoms to watch for include: animals like skunks, moles and raccoons digging up the lawn and birds feeding on grubs and leaving behind pencil-sized holes. Often, the damaged turf will roll back like a carpet as the root system has been entirely eaten away. To check, try lifting up a piece of turf. If it lifts easily this is a sign that the root system has been damaged by white grubs.
Life Cycle of White Grubs
Some grubs complete their life cycle in one year, while others require three years for completion. White grubs survive the winter as larvae in the soil. In the early spring months, they begin to feed again. Later, in the spring and summer, they enter a resting stage (pupae) then hatch into adult beetles. While the beetles themselves do not cause damage to lawns, their presence often signifies an impending grub problem, as their eggs hatch into grub larvae. The larvae then feed voraciously, resulting in significant stress to your lawn. Serious damage can occur in the spring, summer and fall seasons. If the problem is ignored, the patches will only continue to get larger. Left undiagnosed, grubs can devastate an entire lawn in a short period of time.
