Overview

Grubs are an insect that can damage lawns and shrubs by eating their roots if not taken care of in a timely manner. There are many different types of grubs, and while many are eliminated by nature through the predatory habits of other insects or birds, many homeowners seek additional methods of dealing with them, through chemical or organic techniques.

Step 1

Encourage natural predators to grubs for a green-friendly way to deal with grubs that feast on your lawn and shrubs. Natural enemies of grubs include certain species of wasps and ground beetles. Robins find grubs quite tasty, as do other bird species. Place a bird bath or block of bird feed in your yard to attract different species of birds into your yard that will naturally find and eat the grubs.

Step 2

Inspect your lawn on a regular basis for signs of grubs. Common signs of grubs may include yellowed or dying lawn sections or shrubs that suddenly start to lose their color and begin to wilt. Most damage caused by grubs occurs in late summer, so it's best to spot them in late spring or early summer for most effective control and protection of your lawn or yard.

Step 3

Engage in biological or natural controls when possible. One of the best such controls against grubs in your yard is to release nematodes (very tiny parasites transported by water between soil particles) into your yard. These parasites may be purchased through many garden or nursery centers. Ask for application instructions prior to purchase and read instructions that come with the nematodes, watering area before and after application.

Step 4

Spraying the area with chemicals is an option, using products like Merit (imidacloprid) and MACH2 (halofenozide). These types of chemicals must be applied to the lawn or area in early summer, most commonly in June and July for optimal effectiveness. Later than that, and you may need stronger chemicals, such as Dylox (trichlorfon) or Sevin (carbaryl) for more serious infestations.
