Mad About Lawns

Chafer Grubs

Chafer Grubs are a common problem for homeowners with lawns. These small, white, C-shaped insects are the larvae of the European chafer beetle and can cause significant damage to your lawn if left untreated.

They feed on the roots of grass, causing brown patches to appear on the lawn. As they continue to feed, these patches will enlarge and can eventually lead to bare areas of soil. The lawn will appear weak and spongy and can be easily pulled up, as the roots have been eaten away.

In addition to causing damage to the lawn, They can also attract other pests such as birds, moles and badgers, which can further damage the lawn as they dig for the grubs.

To confirm the presence of chafer grubs, you can check for their characteristic C-shaped white bodies in the soil, or check for damage on the lawn such as brown patches or signs of digging.



One of the best ways to control chafer grubs is to use a pesticide specifically designed for grubs. These pesticides can be applied to the lawn in the late summer or early fall when the grubs are most active. It’s important to follow the instructions on the pesticide carefully, as over-application can damage the lawn.

Another way to control chafer grubs is to use nematodes, which are small, beneficial worms that can be applied to the lawn. These nematodes will attack and kill the grubs, providing a natural solution to the problem.

It’s also important to maintain a healthy lawn by providing it with proper fertilization, irrigation, and mowing. A healthy lawn is better able to resist pests and diseases and will recover more quickly from damage caused by chafer grubs.

In conclusion, chafer grubs can be a significant problem but with scarifying, aeration and other techniques they can be beat.
