Japanese beetle grubs also feed on turf roots in home lawns, but they are not usually as much of a problem on home lawns as European chafers can be. Japanese beetles and European chafers lay most of their eggs in July, but Japanese beetles continue laying eggs into August. Japanese beetles like to lay their eggs on irrigated turf like golf courses, athletic fields and highly maintained lawns. They can be abundant in non-irrigated home lawns if we receive frequent rain in July, but are scarce in lawns that are very dry in July and early August.

Wisconsin, Minnesota and Iowa have now joined the club of Midwest states with lots of Japanese beetles, and they have been found in isolated locations as far west as Colorado. The eggs of both species hatch about 10 days after they are laid. The grubs feed from the beginning of August until late October. By the end of October, they are fully grown.

The larvae of both species look almost identical. They spend the winter as large grubs 0. When the ground warms up in spring, they resume feeding and can cause damage from the time the grass turns green until they pupate in mid-May. Grub damage may appear in home lawns from mid-September to November or from March to early May.

However, for low-maintenance lawns, even if the turf is not killed from grub feeding, the thinned and weakened turf may be prone to weeds and drought stress. Healthy turf with a few grubs may not need an insecticide. It is important to realize that healthy turf, supported by frequent rain or irrigation, can support a grub population of five or more grubs per square foot with no visible turf damage.

In fact, most well-maintained lawns do not have visible damage from grubs. A lawn should be mowed at 3 to 4 inches in height and properly fertilized for maximum root growth. However, if the grub population is high or if there is a history of damage in an area, it may be necessary to consider using an insecticide for grub control.

Finding one or two grubs does not indicate you need to apply a grub control product. Check for the active ingredient in a grub product.

However, our experience in the recent past has been that grub damage does not become obvious until September or even into October. Damage from white grubs is usually localized. It is typical to have severe damage in irregular and isolated spots where there were enough soil-dwelling larvae to eat the grass plant roots.

White grub damage may first appear as drought stress gray-green discoloration and wilting in the hot sun. More severe damage causes the turf to die in large irregular patches that can be rolled back like a loose carpet. High populations of grubs may go unnoticed until discovery by raccoons or skunks. Raccoons, skunks and crows will turn over large patches of loose turf, eat the grubs and leave behind a torn-up mess.

Rainfall and soil moisture are critical factors affecting the extent of grub damage. Adequate moisture in mid-summer will favor beetle activity and grub development.
