Identifying and Organically Controlling Grubs in Your Lawn: Milky Spore and Nematodes

Confirmation

Grayish-white, C-shaped larvae under turf = grubs (likely Japanese beetle larvae). They eat roots; adults defoliate roses and other plants. Raccoons/skunks tear turf to eat them.

Organic Controls

Milky Spore Disease: Bacterium (Bacillus popilliae) infects grubs. Apply per label. Takes 1–2 years to establish but lasts decades. Safe, inexpensive. Available at Home Depot. Do not overheat or freeze.
Beneficial Nematodes: Microscopic parasites that target grubs. Use while Milky Spore establishes. Source: Gardens Alive (gardensalive.com).

Why Avoid Chemicals

Synthetic grub killers poison soil biology, harm applicators/residents, and create dependency. Milky Spore + nematodes work with nature.
