Chafer Beetles

Chafer Beetle damage to lawn

Have you noticed patches of dead, spongy grass with areas dug up by crows and raccoons? These are signs that your lawn may have a chafer beetle infestation.

What is Chafer Beetle?

The European Chafer Beetle is an invasive turf pest that was first discovered in the Lower Mainland in 2001.

Living most of its life in the soil, the beetle's wormlike larvae do the most damage by feeding heavily on grass roots, creating visible patches of dead and dying turf.  The chafer larvae (grubs) damage lawns and boulevards by feeding on the roots of turf grass, resulting in the appearance of brown (dead) grass patches in affected lawns. 

Natural predators such as raccoons and crows help reduce their population, but their digging for the larvae can leave quite a mess.

How to minimize Chafer Beetle infestations

A healthy lawn with dense roots is of no interest to Chafer Beetles. Follow these steps to keep your lawn thick and healthy:

  • Aerate regularly
  • Top dress with sandy soil
  • Over-seed
  • Water regularly
  • Reduce mowing

Raccoons and crows digging up your lawn are actually helping by removing many of the beetle larvae. Rake to remove any pulled up sections, and add a top layer of compost and grass seed in the spring to help a healthier lawn return.
