Do Ants Really Disappear in Winter?
Do Ants Really Disappear in Winter?
Many Wisconsin homeowners assume ants vanish once winter arrives. After all, we associate
ants with summer picnics, outdoor trails, and warm weather activity. But if you live in Milwaukee,
Menomonee Falls, or anywhere in southeastern Wisconsin, you may be surprised to learn that
ants can remain active all winter long—just not where you expect them.
Instead of being outdoors, ants often move inside homes, walls, and other heated structures
where conditions allow them to survive until spring.
Understanding winter ant behavior can help you prevent a small hidden issue from becoming a
serious infestation later in the year.
Are Ants Active During Wisconsin Winters?
Yes—but differently.
In cold climates like Wisconsin, ants don’t roam outside during winter. Instead, many species
enter a state similar to dormancy called diapause. During this time, ants slow their activity but
remain alive, protected inside nests.
When those nests are inside or near heated structures, ants can stay active year-round.
Common Ants Found in Wisconsin Homes During Winter
Carpenter Ants
Carpenter ants are the most concerning winter ant species for Wisconsin homeowners.
● They prefer moist or damaged wood
● They commonly nest inside wall voids, attics, and crawl spaces
● They remain active indoors during winter
Because carpenter ants don’t eat wood but excavate it, infestations can lead to structural
damage over time if left untreated.
Pavement Ants
Pavement ants often enter homes through foundation cracks and slab openings. In winter, they
may:
● Nest under basement floors
● Appear in kitchens or laundry rooms
● Forage sporadically when temperatures rise indoors
Odorous House Ants
These ants get their name from the unpleasant odor they release when crushed. During winter,
they may nest:
● Behind walls
● Under floors
● Near heat sources
Because they form large colonies, winter activity often signals a much bigger hidden population.
Why Ants Move Indoors in Winter
1. Warmth
Heated homes create a stable environment ants need to survive cold months. Even wall voids
stay significantly warmer than outdoor temperatures.
2. Moisture
Ants are attracted to moisture from:
● Leaky pipes
● Condensation
● Poor ventilation
Wisconsin winters increase indoor moisture problems, making homes more attractive to ants.
3. Hidden Nesting Opportunities
Wall voids, insulation, and damaged wood offer ideal nesting areas that are rarely disturbed
during winter.
Signs of a Winter Ant Problem
Because winter ant activity is often subtle, homeowners may overlook early warning signs such
as:
● Occasional ants near sinks or baseboards
● Ants emerging during warmer indoor periods
● Small piles of sawdust-like material (carpenter ants)
● Rustling sounds inside walls
Seeing ants in winter almost always means a nest is already established inside the
structure.
Why Winter Ant Activity Shouldn’t Be Ignored
Ignoring winter ant activity often leads to:
● Larger colonies by spring
● Increased structural risk (carpenter ants)
● More difficult and expensive treatments later
Early intervention during winter allows professionals to locate nests while ants are concentrated
indoors.
How to Prevent Winter Ant Infestations
Reduce Moisture Issues
● Repair plumbing leaks
● Improve ventilation
● Address condensation problems
Moisture control is one of the most effective ways to discourage ants.
Seal Entry Points
Ants enter through tiny gaps around:
● Windows and doors
● Foundations
● Utility lines
Professional exclusion helps prevent future infestations.
Avoid DIY Sprays Indoors
Spraying visible ants often scatters colonies and makes infestations worse—especially with
carpenter ants.
