Grub Control in Ohio and Florida

The most common sign of a grub infestation is irregular brown patches of dead grass that peel back like a loose carpet — because grubs have eaten the roots underneath. You may also notice increased activity from skunks, raccoons, or birds digging into your lawn looking for grubs to eat. To confirm, peel back a 1-square-foot section of turf in a suspicious area and count the grubs in the soil just below the surface — finding 5 or more white C-shaped larvae per square foot is a good indicator that treatment is warranted. Damage typically becomes most visible in late summer and early fall when grub populations peak.

The best window for preventive grub control is late spring to early summer — typically June through July — before Japanese beetle and other scarab beetle eggs hatch and the larvae begin feeding on grass roots. Preventive products need to be in the soil when young grubs are small and near the surface, which is when they're most vulnerable to treatment. Curative products can be applied later in summer or fall if an active infestation is confirmed, but they're less reliable on larger, more developed grubs. Applying grub control proactively is more effective than reacting to visible lawn damage, which often doesn't appear until the grubs have already done significant root destruction.

A small number of grubs won't cause serious damage, but a high enough population will destroy large sections of turf by severing grass roots just below the soil surface. Without roots, grass can't take up water or nutrients — it turns brown and dies, and the affected areas often pull away from the ground in sheets. How fast damage spreads depends on grub species, population density, and whether the lawn is already stressed from heat or drought. Lawns that are regularly fertilized and well-watered tend to tolerate lower grub populations better, but even healthy turf can suffer significant damage in a bad year. Preventive treatment is the most reliable way to avoid that outcome.

In most Mid-Atlantic lawns, annual grub control is a worthwhile investment because Japanese beetles and other grub-producing beetles lay new eggs in your lawn each summer regardless of what happened the year before. A preventive application breaks that cycle before the new generation can establish and feed. That said, not every lawn carries the same risk — properties with heavy Japanese beetle pressure, adjacent to wooded areas, or with a history of grub damage are better candidates for consistent annual treatment than a lawn with no history of problems. Land Art can assess your property's specific risk level and give you a straightforward recommendation on whether annual treatment makes sense for your situation.

Grub control products work by targeting the larval stage of beetles before they can establish and feed on grass roots. Preventive products — typically applied in late spring to early summer — are watered into the soil where they're absorbed by the grass plant. When young grubs hatch and begin feeding on roots, they ingest the product and die before populations can build to damaging levels. Curative products work differently: they're designed to kill active grubs already in the soil, though they're most effective on smaller, younger larvae. Watering the treatment in thoroughly after application is important for both product types — it moves the active ingredient down into the root zone where grubs actually feed.
