What are White Grubs?

White GrubsWhite grubs (European chafer, May and June beetles) are small, plump, white larvae which viciously chew on grass roots. They live below the soil surface and actually chew off the roots of the grass. Since the grass roots have been destroyed, the lawn will appear yellow in patches, just like the lawn is dying out. The damage looks quite similar to symptoms of dryness and many Cary, NC Weed Man customers mistakenly assume that the lawn needs only water to restore a lush, green appearance. Other symptoms to watch for include: animals like skunks and raccoons digging up the lawn and birds feeding on grubs, leaving pencil-sized holes. Often damaged turf will roll back like a carpet!

Life Cycle

To control an insect population we must understand its habits and life cycle. Some grubs complete their life cycle in one year. Others require three years to complete their life cycle. White grubs survive the winter as larvae in the soil. In the early spring the grubs begin to feed again. Later in the spring and summer, they enter a resting stage (pupae) then hatch into adult beetles. Cary, NC Weed Man customers beware! Lots of beetles can mean a grub problem later. (The beetles do not damage lawns.) Beetles lay their eggs which hatch into grub larvae. The larvae feed voraciously, which results in the yellowing of your lawn. 

Serious damage can occur in the spring, summer and fall. If the problem is ignored the patches will get larger. The damaged areas will then fill in with weeds or crabgrass. The best time to treat grubs is when they are very young, before you are faced with severe damage. Why wait?
