Grubs are the fat white larvae of various types of beetles. Grubs eat grass roots and can devastate the appearance of a lawn, leaving wide brown patches of dead grass wherever they are active. Grubs hatch in August, so damage in the spring is caused by hardier, older grubs that are more resistant to treatment. Although the most effective time for grub control is in the fall, when larvae are newly hatched, you may also control lawn grubs in the spring.
Things You'll Need
Insecticide
Lawn seeder
Garden hose
Purchase a grub control product. If you want to control grubs in the spring, the University of Rhode Island Horticulture Program specifically recommends an insecticide containing Dylox® (trichlorfon) as one of the more effective springtime chemical applications.
Adjust the lawn spreader to the proper setting according to the instructions on the product.
Treat the border of the lawn first and then fill in the center. Walk at a steady pace and make parallel passes to ensure even distribution of the granules.
Lightly water the lawn to soak the granules into the ground.
Tips & Warnings
The University of Rhode Island Horticulture Program suggests planting shade trees and shade-tolerant grasses for long-term grub prevention. Grubs are not often found in shaded yards.
Do not allow children or pets on the area until the lawn is dry.
