Chafer Beetle Larvae Damage

Chafer beetle larvae feed on grass roots, causing slowed growth, yellow patches, and weakened turf that lifts easily due to poor root development. Adult beetles emerge from the lawn, lay eggs, and the resulting grubs continue to feed on roots before burrowing deep into the soil to overwinter. In spring, they resurface as beetles, repeating the cycle.

Signs of Infestation

Wildlife like foxes, badgers, birds (rooks, magpies, crows, and woodpeckers) often dig up lawns searching for grubs—a clear indicator of a chafer grub problem. Without intervention, the infestation worsens over time.
