What are curl grubs

Curl Grub Larvae have a cream body with a light brown head and they vary in size from 4mm to 40 mm when fully grown. The tail end of the grub may look darker brown which is due to the soil the grub has ingested during feeding. They are often incorrectly referred to as ‘witchetty grubs’. The grubs feed on plant roots in large numbers and curl up when disturbed. Larvae are most active during mid spring to mid-summer, and can cause severe damage to lawns, gardens and potted plants.

 

Symptoms
