A Natural Way to Rid the Grass of Grub Worms
- 1). Use a spade to lift up 1 square foot of browning turf in your lawn. Count the grubs present to see if the population is high enough to warrant taking action. If you have 10 or more grubs per square foot, you will need to control the population. Check the lawn in early August, before the grubs become active.
- 2). Walk your lawn with a lawn aerator three to five times. The spikes on the aerator will kill the grubs under the turf.
- 3). Stop watering your grass as soon as grubs are detected. Grubs require moist, well-irrigated grass to survive. If the turf dries out, the grubs will die. The grass may die or go dormant, but it will break the life cycle of the grubs.
- 4). Reseed the turf in areas that suffered grub damage or areas of the yard that died when you stopped watering. The time of year when you reseed depends on your turf species, but it will either be in spring or summer.
- 5). Water and fertilize the newly seeded lawn according to the seed package directions. Creating a healthy lawn with deep roots will help it survive future grub attacks without showing much, or any, damage.
