Lawn grubs are one of the most destructive pests a homeowner can face. These white, C-shaped larvae live beneath the soil surface and feed on grass roots, causing brown patches, thinning turf, and sections of lawn that peel up easily. If left untreated, grubs can destroy an otherwise healthy lawn in a single season.

How to Choose the Best Lawn Grub Killer
Choosing the right grub killer depends on your lawn’s condition and your treatment goals.
Active Infestation vs Prevention
If your lawn already shows signs of grub damage, a fast-acting product like a liquid spray or curative granular treatment is best. For lawns without visible damage, preventive products provide better long-term protection.
Lawn Size
Granular products and hose-end sprays work well for larger lawns, while biological treatments can be effective for both small and large areas, depending on application rate.
Chemical or Natural
Chemical grub killers offer quick and broad insect control, while natural options such as nematodes and milky spore focus on environmental safety and sustainability.
Speed of Results
Some products work within days, while others require weeks or even seasons to reach full effectiveness. Understanding your expectations will help you choose the right solution.
