Many gardeners know that pests can survive the winter by going into a state of hibernation. While they cause no harm during the cold months, they become active again in the spring, wreaking havoc on your plants. So, where do these pests hibernate, and what can you do to ensure they don’t return in full force?

Common Places Where Pests Hibernate

  1. On Trees and Bushes:
    Some pests overwinter in the bark of trees and bushes. For example:

    • Red spots on the bark often indicate the larvae of the apple scale.
    • Orange eggs near the base of tree branches are from the unpaired silkworm.
    • Caterpillars of the plum and apple borer also hibernate under the tree bark.
  2. In Leaves and Shoots:
    Many pests hibernate in the leaves and young shoots of plants.

    • Whiteflies build nests in leaves, where their caterpillars hibernate.
    • Red apple mites and goldenrod also overwinter in these areas.
    • The viburnum leaf-eater and winter moth hide in young shoots.
    • On the young bark, pests like the apple copperhead, aphids, and ringed silkworm also spend the winter months.
  3. In Soil and Leaves:
    Many pests find favorable conditions in the soil and fallen leaves.

    • The strawberry mite and weevil often hibernate here.
    • The cruciferous plaque survives the winter in the soil.
    • Currant and gooseberry pests like the bonfire cocoon themselves in leaves.

Preventing Spring Infestations

To reduce the number of pests that will affect your garden in the spring, it’s essential to treat your trees and plants before winter arrives. By doing so, you’ll minimize the number of pests that survive the season and prevent them from causing damage when the weather warms up.

Taking these proactive steps now will help ensure your garden remains pest-free throughout the growing season.
