Most gardeners are aware that pests can survive winter by entering a state of hibernation. While dormant during winter, these pests can wreak havoc once spring arrives. Let’s explore where pests hibernate and how to prevent their resurgence in spring.

Where do pests hibernate?

Some pests prefer to spend winter in bushes and on tree bark. Red spots on bark can indicate larvae of the apple scale, while orange eggs at the base of stems belong to the gypsy moth. Plum and apple borers hibernate as caterpillars under tree bark.

Others hibernate in leaves and young shoots. Whiteflies create nests on leaves woven with webs, where their larvae also hibernate. Red apple mites and golden ear mites also survive the winter this way. Viburnum leaf beetles and winter moths overwinter in young shoots. Aphids, apple aphids, and ringed silkworms find shelter on young bark.

Many pests hibernate in leaves and soil. Strawberry mites and weevils thrive in these conditions. Cabbage worms hibernate in soil, while currant and gooseberry sawflies, wrapped in cocoons, peacefully await spring under a layer of leaves.

Prevention before winter

To minimize pest populations in spring, it’s crucial to treat trees and plants before winter arrives. This proactive approach can significantly reduce the number of pests that emerge when temperatures warm.

By understanding where pests hibernate and taking preventive measures, gardeners can protect their plants and ensure a healthier garden in the coming seasons.
