Lawn grubs live in the soil eating grass roots and leaving your yard brown and unattractive. Not only can these pests damage the lawn, but their presence also invites unwelcome wildlife that feed on lawn grubs – digging up patches of grass in search for them. The majority of grub worms come from Japanese beetles, which lay their eggs in midsummer in sunny areas of the lawn. Taking care of this problem is simply a matter of how to detect grub worms and when to apply grub worm treatment.
Visible lawn grub damage can be seen from late summer to early fall. Look for irregular brown patches of lawn that peel away easily from the soil, like carpet. To determine the extent of infestation or which areas require treatment, dig up small sections of lawn. Typically, more than five grub worms per ¼ square foot warrants treatment and lawn grub control.
