How to Control Lawn Grubs

Overview

When a Japanese beetle lays an egg, it hatches and becomes a grub. Many animals dig up lawns and gardens to eat the grubs. The grubs also cause destruction to lawns as they eat up grass roots. If grubs are becoming a problem in your lawn, you can control them with nematodes. Nematodes are tiny unsegmented worms that are harmless to children and pets, but they do consume grubs found in soil.

Step 1

Purchase a package of nematodes from your local garden center. If your local garden center does not carry them, you can get them online.

Step 2

Mix the package of nematodes with 2 gallons of water.

Step 3

Pour the nematode mixture into your hose end sprayer. Two gallons will cover a total of 1,000 sq. ft. Hook up the hose end sprayer to your garden hose.

Step 4

Spray the areas of your lawn where you want to control the grubs. You should begin to see results in as little as three days.
