White grubs are the larvae of Japanese beetles, June bugs, and other beetles that lay eggs in lawns across Rice County every summer. They hatch in late summer and feed on grass roots just below the surface — leaving dead patches that peel back like carpet.
The Problem
Root feeding damage
Grubs feed on grass roots 1–3 inches below the surface. By the time you see brown patches appearing in August and September, significant root damage has already occurred. Prevention is far more effective than treatment after the fact.
Secondary Damage
Birds and skunks
Raccoons, skunks, and birds detect grubs below the surface and tear up turf to get to them. This secondary damage is often more visible and more damaging than the grubs themselves. Faribault lawns with grub problems frequently see this kind of digging.
Timing
Early summer application is critical
Preventative grub control must be applied before grub eggs hatch — typically June through early July in southern Minnesota. Applications timed correctly protect the entire season. Curative treatments applied after hatching are significantly less effective.
Protection
Season-long control
A single properly timed application provides season-long protection against grub damage for your Owatonna, Austin, or Rochester lawn. Included in our Peak Performance program or available as a standalone add-on to any treatment plan.
