Hibernate, Migrate, or Invade? What Happens to Bugs When Temperatures Drop?
As temperatures drop and the world outside slows down, have you ever wondered where all the bugs go? Insects may not be buzzing around your head or creeping across your kitchen counter as often, but that doesn’t mean they’ve disappeared. The way pests survive winter is fascinating and varied. Let’s dive into how pests endure the cold months—and what it means for your home.
How Do Pests Survive the Winter?
The answer is as diverse as the pests themselves. Some migrate, others hibernate, and many simply find a warm place to ride out the cold. Here's a breakdown of their winter strategies:
Overwintering
Overwintering refers to the process insects use to survive winter in a dormant state. Rather than migrating or fully hibernating, many pests remain in their environment at various life stages—larvae, pupae, eggs, or nymphs. These stages are designed to withstand cold temperatures, allowing the insects to emerge as adults when spring arrives.
Hibernation
Like bears, many insects hibernate during the winter. They find cozy spots like holes in trees, spaces under logs, or cracks in your home to stay warm and inactive. While they’re unlikely to cause much trouble during hibernation, pests hiding in your home can become a significant issue once spring rolls around.
Migration
Some insects, like monarch butterflies, migrate to warmer climates just like birds. While monarchs are the most well-known migrating insects, other species, including some crop pests, also head south to survive the cold.
How Common Pests Survive Winter
Wasps
At the end of the season, only fertilized queen wasps survive. These queens hibernate in sheltered locations, like under bark or inside cracks, until spring. Once warm weather returns, they’ll establish new nests and lay their eggs.
Mosquitoes
Male mosquitoes don’t survive the winter, but female mosquitoes do. They hibernate in hollow logs or other sheltered spots, waiting for warmer days. Some species overwinter as larvae or pupae, developing into adults when spring arrives.
Ladybugs
Ladybugs are notorious for seeking shelter inside homes during the winter. While they appear inactive, their infestations can grow quickly. If you find ladybugs in your home, it’s important to address the issue before they become a bigger problem.
