The larva of the May/June beetles, also called May or June bugs, are white c-shade grubs that have a three year life cycle. Noticeable damage to the turf doesnât occur until late in the second year. For the best control, a basic knowledge of life cycles is important. First Year.
For most species and locations that means July or August is the prime time to treat with an insecticide. However, because grub populations vary from year to year, you may be able to save the cost of treatment if you first sample your lawn to estimate how many grubs are present. Dig up several pieces of sod about a foot square. If you find five or fewer grubs per square foot, you need not apply grub control. The lawn will withstand the amount of feeding these few grubs do. If 10 or more grubs are present, treat your lawn for grubs. If the average count is between five and 10, whether or not to control depends on the health of your lawn, your tolerance for damage to the lawn, and presence of natural controls.
