Virtually wingless, female winter moths hatch in November, then crawl up fruit trees to mate with male moths. The eggs that are laid hatch into caterpillars in spring, which eat the leaves and flower buds of the affected tree.

Usually they cause very little damage and don’t reduce the overall fruit yield. However, in large numbers, they can weaken the tree and reduce yields. In these cases you may wish to trap and kill female moths before they climb the trunk to mate, by attaching a grease band to your fruit trees.

Follow our guide to controlling winter moth, below.
