Grub Control & Lawn Pest Treatment in Rochester Hills

By the time you see the damage, grubs have already been feeding for weeks. Brown patches that peel up like carpet, skunks and raccoons tearing holes in your lawn at night, birds pecking aggressively at the turf — these are all signs of a grub infestation that's already well underway. At that point, you're treating the problem and repairing the damage, which costs significantly more than preventing it in the first place.

White grubs are the single most destructive insect pest for lawns in Rochester Hills and Rochester, Michigan. They feed on grass roots below the surface where you can't see them, and by the time the turf shows stress, the root system is already compromised. Every golf course superintendent in Oakland County treats for grubs preventively — not because they might have a problem, but because the cost of prevention is a fraction of the cost of repair.

At SMC, we apply the same preventive approach to residential lawns. Our licensed pesticide applicator uses professional-grade products at calibrated rates to protect your lawn before grubs ever become a visible problem.

The Grub Problem in Rochester Hills

Rochester Hills sits squarely in the territory of three major grub-producing beetles: Japanese beetles, European chafers, and June bugs. All three are well-established in Oakland County, and their larvae — white, C-shaped grubs — feed on grass roots from late July through October, then again briefly in spring before pupating into adult beetles.

Japanese Beetle Grubs

Japanese beetles are the most visible of the three — you've seen the metallic green and copper adults stripping leaves off roses, lindens, and birch trees in July. Their grubs are the most common lawn pest in the 48306, 48307, and 48309 zip codes. A single female lays 40 to 60 eggs in the soil during summer, and those eggs hatch into root-feeding grubs within two weeks.

European Chafer Grubs

European chafers are less noticeable as adults but their grubs are equally destructive. They're particularly common in Rochester Hills because they thrive in the irrigated lawns that dominate our neighborhoods. Chafer grubs feed later into fall than Japanese beetle grubs and resume feeding earlier in spring, extending the damage window.

June Bug Grubs

June bugs (May beetles) have a longer lifecycle — their grubs feed for two to three years before pupating. This means grub populations can build up over multiple seasons even without obvious adult beetle activity. They tend to cause damage deeper in the soil profile than the other two species.

Signs of Grub Damage

Preventive vs. Curative Grub Control

Preventive Treatment (Recommended)

Applied: June to early July — Preventive grub control uses long-residual insecticides that remain active in the soil for weeks, killing grub larvae as they hatch from eggs in mid-to-late July. This is the same approach used on every professionally managed golf course and sports field in Michigan.

Preventive products are more effective, less expensive per application, and eliminate the problem before any damage occurs. One properly timed application protects the lawn for the entire grub feeding season. This is the treatment we recommend for every Rochester Hills lawn.

Curative Treatment (When Prevention Was Missed)

Applied: August to September — If grubs are already present and feeding, curative insecticides can kill active grubs. However, curative products work on a shorter timeline, may require higher rates, and — critically — the damage has already been done. You'll still need to repair the lawn after treatment through overseeding, slit seeding, or renovation.

Curative treatment costs more than prevention when you factor in the lawn repair that follows. This is why we strongly recommend getting on the preventive schedule.

Other Lawn Pests We Treat

Chinch Bugs

Chinch bugs feed on grass blades (not roots) by piercing stems and sucking plant fluids while injecting a toxin that kills the surrounding tissue. Damage appears as irregular yellow-to-brown patches, typically in the hottest, driest areas of the lawn — along driveways, sidewalks, and south-facing slopes. Chinch bug damage is often misdiagnosed as drought stress.

Treatment involves targeted insecticide application to affected areas and surrounding turf. Proper identification is critical — chinch bug damage looks similar to drought, disease, and other issues, and misdiagnosis means wasted product and continued damage.

Sod Webworms

Sod webworms are the larvae of lawn moths — the small tan moths you see fluttering over the lawn at dusk in summer. The larvae feed on grass blades at night, creating closely cropped patches with visible frass (tiny green pellets) at the soil surface. Damage is most common in July and August when second-generation larvae are actively feeding.

Surface-Feeding Insects

We also treat for armyworms, cutworms, and other surface-feeding insects that can cause rapid damage to Rochester Hills lawns during summer. These pests can strip large areas of turf in just a few days when populations spike, so quick identification and treatment is important.

Grub Control FAQs

When should I apply grub prevention in Rochester Hills?

June through early July is the preventive window for Rochester Hills lawns. The product needs to be in the soil before grub eggs hatch in mid-to-late July. Don't wait until you see damage — by then, prevention is no longer an option.

How do I know if I need grub treatment?

If you've had grub damage in the past, or your neighbors have, preventive treatment is strongly recommended. Grub populations are well-established throughout Rochester Hills and Rochester. If you're unsure, pull back a section of turf in a brown area — more than 5 to 8 grubs per square foot indicates a population that will cause visible damage.

Is grub treatment safe for kids and pets?

Professional-grade grub control products are applied to the soil surface and watered in, moving the active ingredient below the surface where grubs feed. Once watered in and dried, treated areas are safe for normal use. We provide specific re-entry timing with every application.

Will grub treatment also control Japanese beetles on my plants?

Soil-applied grub control targets larvae in the soil and does not directly control adult beetles feeding on ornamental plants. However, reducing grub populations in your lawn means fewer adult beetles emerging from your property the following summer. For active beetle control on shrubs and trees, we offer targeted foliar insecticide applications.

My lawn already has grub damage — what now?

If it's August or September, we apply curative insecticide to stop active feeding, then develop a repair plan. Depending on damage severity, repair typically involves core aeration and overseeding for moderate damage, or slit seeding and top dressing for severe areas. We handle both the pest treatment and the lawn restoration.
