Chafer grubs

Overview

Chafer beetle larvae feed on roots, causing wilting and patchy collapse.

Often confused with vine weevil larvae.

Chafer grubs are root-feeding larvae and are usually most damaging where plants are grown in soil, turf, nursery beds or outdoor containers.

Risk is often linked to field history. Areas with previous grass, weedy margins or poor rotation history may carry higher populations.

Useful monitoring includes checking weak plants, lifting suspect root zones and looking for curved white grubs in the soil.

Control is usually strongest when based on prevention, field history and good timing rather than waiting until plants collapse.
