Damage caused by summer chafer grubs

The main damage is caused by June beetle grubs in the 3rd larval stage. They feed underground on the grass roots, hindering water and nutrient uptake by the plants. June beetle larvae cause brown spots in the turf, the turf is easily pulled off, masses of grubs appear; dry turf in places.

Birds and other animals (e.g. wild boars) also destroy the turf by pecking and burrowing in search of the tasty grubs. Infestations include private lawns, public green spaces, sports turf, and golf courses.
