Common Winter Pests in the Southeast
Winter in the Southeast doesn’t look like winter in many other parts of the country. While temperatures drop, long cold freezes are rare — and that mild climate changes how pests behave. Instead of disappearing for months, many pests simply move closer to warmth, often ending up inside homes.
For homeowners, this can be confusing. You may expect pest problems to slow down in winter, only to notice ants in the kitchen, spiders in corners, or rodents in the attic. Understanding which pests remain active — and why — is the first step toward protecting your home year-round.
Why winter pest problems are common in the Southeast
The Southeast’s climate creates a unique pest environment:
- Winters are shorter and milder
- Soil rarely freezes deeply
- Insects and rodents stay active longer
- Homes offer consistent warmth and shelter
Instead of going dormant, many pests simply relocate indoors when temperatures dip. This makes winter one of the most important seasons for prevention.
Ants
Ants are one of the most common winter pests in the Southeast.
Why ants come inside
- Cold temperatures reduce outdoor food sources
- Rainy winter weather floods nests
- Homes provide warmth and easy access to food
You may notice ants along baseboards, in kitchens, or near bathrooms — especially during cold snaps followed by warmer days.
Why winter ants matter
Seeing ants in winter often means there’s a nest nearby, sometimes inside walls or under foundations. Without proper treatment, these colonies rebound quickly in spring.
Spiders
Spiders don’t hibernate the way many homeowners think they do.
Why spiders stay active
- They follow insects indoors
- Warm indoor temperatures keep them moving
- High corners and storage areas provide ideal hiding spots
While most spiders in the Southeast are harmless, their presence often signals other pest activity, since spiders go where food is available.
Cockroaches
Cockroaches are year-round pests in the Southeast — winter included.
Why cockroaches thrive in winter
- They prefer warm, humid indoor environments
- Plumbing areas and kitchens provide moisture
- They hide deep in walls and appliances
German cockroaches, in particular, reproduce quickly and are rarely eliminated without professional help.
Winter warning sign
Seeing roaches in winter almost always indicates an established infestation, not a seasonal fluke.
Rodents (Mice and Rats)
Rodents are among the most problematic winter pests for homeowners.
Why rodents invade homes
- Cold weather reduces outdoor shelter
- Homes provide warmth, nesting materials, and food
- Small entry points allow easy access
Rodents commonly nest in:
- Attics
- Wall voids
- Crawlspaces
- Garages
Beyond property damage, rodents can contaminate food and create health risks.
Stink Bugs
Stink bugs are classic winter “invaders” in the Southeast.
Why stink bugs show up in winter
- They seek warm overwintering sites
- Homes mimic rock crevices and tree bark
- They enter through small exterior gaps
While they don’t reproduce indoors, they can appear suddenly and in large numbers during warm winter days.
Silverfish and Firebrats
These moisture-loving pests often go unnoticed until winter.
Why they thrive indoors
- Bathrooms and kitchens provide humidity
- Basements and crawlspaces stay warm
- Paper products offer food sources
They’re not dangerous, but their presence usually indicates moisture issues that should be addressed.
Wasps and Other Stinging Insects
While wasps don’t build nests in winter, they’re still relevant.
What happens in winter
- Only fertilized queens survive
- Queens overwinter in protected spaces like attics
- Warm winter days can trigger brief activity
Ignoring winter wasp sightings can lead to new nests forming near your home in spring.
Why winter is a critical time for prevention
Many homeowners wait until spring to think about pest control — but by then, infestations are already established.
Winter is ideal for:
- Identifying entry points
- Reducing indoor nesting sites
- Addressing moisture issues
- Preventing spring population explosions
At Specter Pest Control, winter inspections often uncover small issues that would turn into major infestations if left untreated.
Common winter pest entry points
Most winter pests enter homes through tiny openings, including:
- Cracks in foundations
- Gaps around doors and windows
- Utility line penetrations
- Damaged soffits or siding
- Unsealed crawlspaces
Sealing these areas not only helps with pest control — it also improves energy efficiency.
What homeowners can do now
Here are simple steps to reduce winter pest pressure:
- Seal exterior cracks and gaps
- Store food in airtight containers
- Reduce indoor clutter
- Fix leaks and moisture problems
- Keep firewood away from the house
- Clean garages and storage areas
These steps help, but they don’t replace a professional inspection — especially in pest-heavy regions of the Southeast.
