GrubEx

Grubs can do extensive damage to lawns by feeding on grass roots. Damaged turf turns brown and is easily pulled up by hand (or skunks looking for a snack!). Prevent turf damage with Scotts GrubEx Season Long Grub Killer. A single application of this granular insecticide can kill and prevent grubs for up to 4 months.

This grub killer also kills caterpillars (armyworm), chinchbugs, May/June beetles, and more (as listed), and can help control Japanese beetle infestations when applied annually. Apply Scotts GrubEx Season Long Grub Killer to a dry lawn in the spring or early summer to kill grubs as they develop.

Water in thoroughly to activate. 

People and pets may re-enter the lawn after it has dried.
