Adult garden chafers do not cause significant damage to the plants that they feed on. The larval grubs however, often cause yellow patches to appear on lawns where they are feeding on the roots. This can result in dead patches. A number of plants can also be damaged in this way. Large numbers of garden chafer grubs can occur within large lawns and amenity turf areas such as golf courses. Badgers and crows will often dig into the grass to find and eat the grubs causing serious damage.
