Is there a way to treat grubs that are tearing up a yard that is near a lake? The preventive grub x had a warning with water? Thank you.

For general information on grub control. Several alternative chemicals are listed. Read the labels to find one that is not harmful to water, pollinators, etc.

The active ingredient on GrubX is chlorantraniliprole. This article near the end, has a warning about its damage to aquatic life.
