Are you developing ugly brown patches in your yard, but you feel like you’re constantly watering? Rest assured, it’s not for the lack of watering. Mid-August through September is when your yard starts to show the impact of grubs.
What are grubs?
Grubs are the larvae of a variety of different types of beetles, including Japanese beetles and June Bugs. Beetles will typically lay their eggs in July, and they hatch about 2-4 weeks later. New larvae begin feeding almost immediately. At full grown, a grub can get to be about 2” long. Gross!
How do I know if its grub damage?
Immediately after they hatch, grub worms begin feeding on the turf’s root system. The more grubs, the more damage to your turf. The damage will appear as wilting and browning grass in irregular shaped areas around your lawn. Since grubs feast off the root system of your turf, your lawn will become very loose and peel back almost as if it’s new sod. Once the turf is peeled back, the grubs will be easily visible.
Pictured above is a severe case of grub damage. You can see how easily the turf pulled back.
When’s the best time to treat for grubs?
Best time to treat for grubs is early, before the damage can occur. By treating early, it can prevent the hatching and further maturity of the grub worms.
I have grub damage — what can I do?
Typically, at this stage damage control is the only way to assess the problem with a granular insecticide. Dylox is known to be effective and can yield excellent results when applied to prevent and treat lawns infected with grubs. Dylox is typically applied to the damaged and surrounding area to stop the spread of further damage. Unfortunately, the damaged area typically will not rebound, and the area will need to be racked out and re-seeded in the early spring or early fall leaving large, bare spots in your lawn. We also recommend have an aeration and overseeding treatment to help fix those areas and thicken your lawn.
