Grubs will live in your lawn and can be identified by their soft, white, C-shaped bodies with legs located up near the head. They are actually the larvae of different beetle species, including the Japanese beetle, the European chafer, and the Green June beetle, among others. Grubs will eventually turn into adult beetles and complete their life cycle upon laying their own eggs in the soil.
How to check if you have grubs
If grubs are allowed to proliferate and complete their life cycles, they will quickly begin causing damage to your lawn by feeding on your turfgrass roots. A lawn that has been weakened by grubs will be easier to roll back. You may also see signs of damage caused by animals digging into your grass for the grubs.
How to get rid of grubs
Grubs can be effectively controlled with the timely application of a quality grub killer. You have a few different options for when to apply the product.
If applied in the springtime (from April to late May) to the thawed ground, the grub killer will eliminate grubs that have overwintered and are heading to the surface, while a summer application (from late June to early August) will help control newly hatched larvae. Grub killer can also be applied in the fall (from late August to September) to prevent grubs from overwintering and lessen their impact on your lawn next spring.
