Overwintering Pest Facts You Should Know

Winter brings cold weather and a break from many outdoor pests. But some pests don’t disappear. Instead, they find ways to survive the cold months by overwintering. Understanding how pests overwinter can help you protect your home or business from infestations when the weather warms up again.
I want to share some important facts about overwintering pests. This knowledge can help you spot signs early and take action before pests become a problem. I’ll also mention a couple of pest control services that can help keep your property safe during winter and beyond.
What Does Overwintering Mean?
Overwintering is how certain pests survive through the winter season. Instead of dying off, they find shelter in warm, protected places. These places can be inside your walls, under leaves, in cracks, or even inside your home.
Pests enter a state of dormancy or reduced activity to conserve energy. This allows them to survive cold temperatures and limited food sources. When spring arrives, they become active again and start looking for food and places to breed.
Common overwintering pests include:
Ladybugs
Spiders
Stink bugs
Rodents like mice and rats
Termites and ants in some cases
Knowing where and how these pests hide can help you prevent infestations.
How Pests Choose Overwintering Spots
Pests look for places that offer warmth, moisture, and protection from predators. These spots are often close to food sources or entry points into buildings.
Some common overwintering locations are:
Cracks and crevices in walls and foundations
Attics and basements
Behind siding or shutters
Inside firewood piles
Under mulch or leaf litter
For example, ladybugs often gather in large groups on sunny sides of buildings. They seek small openings to slip inside and stay warm.
Rodents look for cozy spots with easy access to food, like garages, storage sheds, or inside walls.
Signs of Overwintering Pests in Your Home or Business
You might not notice pests right away during winter because they stay hidden. But there are signs to watch for:
Clusters of insects on windows or walls
Small holes or cracks in walls or foundations
Droppings or gnaw marks from rodents
Unusual smells, like a musty or oily odor
Sounds of scratching or movement inside walls or ceilings
If you see any of these signs, it’s a good idea to inspect your property carefully. Early detection can save you from bigger problems later.
How to Prevent Overwintering Pests
Preventing pests from entering your property is the best way to avoid infestations. Here are some practical steps:
Seal cracks and gaps around windows, doors, and foundations
Install door sweeps and weather stripping
Store firewood away from the house and off the ground
Keep gutters clean and dry to avoid moisture buildup
Remove leaf litter and debris near your building
Use screens on vents and chimneys
Taking these steps before winter sets in can reduce the chances of pests finding shelter in your home or business.
