Pests are often a nuisance during the warmer months but they seemingly disappear in winter. Where do pests go during winter months? Most of us assume that pests die off or go back into the ground in winter. However, the truth is that most pests find ways to survive in winter. In this article, we will talk about various strategies employed by pests to survive in cold months and the effects of their winter behaviors on pest management.

Diapause/ Hibernation: A Strategy of Inactivity

Pests use diapause or hibernation as a survival strategy during winter months. It is a period of suspended development in an insect. This allows pests to conserve energy and bear the cold winter months where there are unfavorable conditions for food sources. Some go into hibernation mode, which is a deep sleep that helps them to save energy and survive winter without eating much.


Many insects including ladybugs and certain types of moths go into diapause during winter months. They find shelter in tree barks, cracks, and crevices in homes to stay safe during colds. Such insects can survive for months without food or movement until warm weather brings back them to life.


Rats and mice also go into hibernation less pronounced than insects. Rodents become less active and spend less time in the movement. They hide in burrows or buildings to preserve heat and energy.


Some pests escape the cold winters by migrating to warmer climates. When the temperature drops and the food becomes insufficient, they migrate to temperate climates. Some species of birds like house sparrow is known for this behavior. Likewise, some species of butterflies also take significant migrations covering thousands of miles in warmer climates. This ensures their survival in the winter months.


It is the process by which some pests pass through or wait out the winter season. They remain active throughout the winter. For example, honeybees huddle in their hives during winter buzzing their wings to generate heat and maintain temperature inside the hive. This shared warmth ensures the survival of the colony during winter months. Similarly, cluster flies are other pests that overwinter in cold months. They invade homes and seek shelter in walls, basements, and attics and remain inactive during winters.

Burrowing and Tunnelling

Some insects like earthworms, beetles, and grubs burrow into the soil to avoid freezing temperatures. The soil provides insulation and helps to keep the temperature stable. Some pests also tunnel into buildings and outdoor structures to find refuge.

Adapting to Environmental Changes

They may also reduce their search for food and save energy by consuming stored food. Cockroaches are adaptable to different environments but they prefer warm temperatures finding safe  haven in your homes during the winter months.

Winter is the time of year when pests like mice, rats, and cockroaches find their way into homes and buildings in search of warmth and shelter. Other common winter pests include spiders, cockroaches, and cluster flies. Rodents can squeeze through tiny openings and gain access to your house. Cockroaches and cluster flies enter homes and once they are inside, they remain hidden and inactive during winter.
