Many people assume that pests disappear when temperatures drop, but in reality, winter often brings an increase in indoor pest activity. As temperatures fall, pests that typically live outdoors start seeking warmth, food, and shelter inside homes. Understanding which pests are most active in winter and how to manage them can help prevent an infestation before it becomes a bigger problem.
Common Winter Pests and Why They Invade Homes
Mice
Mice are one of the most common winter pests. When the weather gets cold, they look for a warm place to nest and an easy food source. Since mice can squeeze through openings as small as a dime, even the smallest gaps in your home’s foundation, walls, or vents can serve as an entry point.
Signs of a mouse infestation include:
- Droppings in cupboards, drawers, or along baseboards.
- Gnawed food packaging or electrical wiring.
- Scratching noises in walls or ceilings, especially at night.
Spiders
Spiders don’t migrate or hibernate in the winter, but as temperatures drop, they become more noticeable inside homes. Many spiders follow their food sources, meaning if other insects are present, spiders will be too. They tend to hide in dark, undisturbed areas like basements, attics, and storage rooms.
Although most household spiders are harmless, species like black widows or brown recluses can pose risks with their venomous bites. Keeping your home free of clutter and sealing entry points can reduce spider activity indoors.
Silverfish
Silverfish thrive in humid environments, making bathrooms, basements, and laundry rooms ideal hiding spots. These pests are known for their fast, darting movements and can survive in cold temperatures as long as they have access to moisture.
Silverfish infestations can cause damage over time as they feed on:
- Paper and cardboard.
- Book bindings.
- Clothing and stored fabrics.
What to Do If You Find Winter Pests Indoors
Once pests have found their way inside, taking action early is key to preventing a full-blown infestation. Some simple steps to manage and reduce winter pest activity include:
- Inspect and seal entry points – Look for cracks, gaps, and holes around doors, windows, pipes, and vents. Use caulk or weather stripping to close off access.
- Reduce moisture and humidity – Many pests thrive in damp environments. Use dehumidifiers in basements and ventilate bathrooms properly.
- Maintain cleanliness – Store food in airtight containers, vacuum regularly, and eliminate clutter where pests might hide.
- Set humane traps for mice – Instead of using glue traps or poisons, opt for live traps that allow for safe capture and relocation.
