23 Jan Curl Grub

Description: White grubs with orange heads and greyish tail ends of around 40mm in length. These are the larvae of various beetles (including Christmas Beetles) and typically curl into a β€˜c’ shape when removed from the soil.

Damage Caused: Curl grubs pose a problem in the garden when they accumulate in large numbers in either pots or garden beds. There they chew on the root system of plants, weakening them and often causing their death. The odd curl grub found whilst digging in the garden is not an issue and no need to treat. Curl grubs in the compost bin are also of no concern and are actually helping breakdown the organic matter. Compost will generally be picked-clean by birds on application.

Control: Grubs can be fed to birds as they are discovered in the garden.

Green: Botanical oils products (eg. Eco-Grub, Eco-Neem) can be applied to the soil as a drench.

Orange: Confidor can be applied to areas of lawn and garden as well as to pots. NB Care should be taken when using the above chemical as it is harmful to foraging bees. As a rule I only use these on plants that are not currently in flower (including Clover in lawns) to avoid the risk to bees that are so vital in the garden.

Red: Not required for this pest.
