The European Chafer Beetle is an invasive insect pest. Its larvae feed on the roots of grasses, causing serious damage to lawns.

Adult Chafer Beetles are tan or brown, measuring approximately 1.5cm (0.5in) long. The larvae (or grubs) have brown heads and white, C-shaped bodies, and they’re smaller than a dime.

How do I know if I have a Chafer Beetle infestation?

Chafer Beetle infestation is often most visible when raccoons, birds and other wildlife, eager to eat the grubs, begin digging up grasses and damaging turf.

Between January and March you can monitor your grass for grubs by cutting back a section of the turf and digging around in the dirt. If there are more than five grubs per section, you may want to consider Chafer Beetle control.

Lawn Alternatives

Many low-maintenance materials are available to replace grass, from drought-tolerant groundcover plants and mulch to rock gardens and gravel.  

Consider replacing some or all of your lawn with drought-tolerant groundcover plants that do not attract Chafer beetle, such as microclover, brass buttons or creeping thyme. Your garden centre can provide advice about selecting plants that are not invasive and suit your surroundings.

It’s important to avoid invasive species that will spread aggressively, kill off native plants and can cause erosion and destroy habitat. Some, like Giant Hogweed, are also dangerous to human health.
