How to Stop Grubs & Lawn Insects Naturally

Overview

Many different natural remedies exist for getting rid of grubs and other lawn insects. Nearly all of the organic pest remedies for lawns involve introducing natural predators to the grass, whether they're predatory insects, bacteria or fungi. These natural predators of grubs and lawn insects will effectively get rid of the lawn pests, without harming humans, pets or other animals. These organic remedies for grubs and lawn insects restore the natural balance of your lawn, as well as the environment around your home.

Step 1

Select a lawn grass seed that contains the symbiotic fungi endophytes. Endophyte-enhanced turfgrasses are toxic to billbugs, sod webworms and chinch bugs that feed on grass.

Step 2

Introduce parasitic wasps, such as the Tiphia species, to get rid of white grubs in your lawn. Parasitic wasps will feed on the grubs of masked chafers, Japanese beetles and June beetles.

Step 3

Introduce beneficial nematodes to your lawn to control billbugs. Species of entomophagous nematodes, such as Steinernema carpocapsae and S. glaseri, will effectively get rid of billbugs. You can also introduce the nematode species Heterorhabditis bacteriophora to your lawn to control both billbugs and white grubs.

Step 4

Apply the bacterium Bacillus thuringiensis Berliner to control sod webworms and other kinds of damaging caterpillars. You can also introduce predatory ground and rove beetles to control sod webworm populations in your lawn.

Step 5

Apply Milky Spores to your lawn to get rid of Japanese beetle grubs. Apply the Milky Spores in the spring or fall, when the grubs are actively feeding. Stop raking or mowing your lawn for two or three days after applying the Milky Spores, to allow them to penetrate into the sod.

Tips and Warnings

  • You must de-thatch your lawn every year in early spring to remove the food and hiding places for lawn insects. Water or irrigate your lawn during the hotter, drier summer months to eliminate chinch bugs, which are injured from the water droplets.
