How deep do wireworms typically overwinter in the soil?

Wireworms, which are the larvae of click beetles, typically overwinter in the soil within a depth range of 12 to 24 inches. This depth allows them to avoid harsh surface conditions and maintain a stable environment that helps protect them from extreme cold and desiccation during the winter months.

Choosing this depth is important for their survival, as it places them below the frost line in many regions, providing insulation from cold temperatures that could be lethal. The behavior of wireworms in these depths also impacts agricultural practices, as understanding their overwintering habits can aid in developing effective pest management strategies for crops.

In contrast, the other depth ranges would either expose wireworms to harsh conditions or place them in areas where temperature fluctuations could be detrimental, making them less favorable for overwintering.
