If you’ve spotted large black ants crawling around your Maine home in late winter – before spring has even officially started – you might be wondering what’s going on. Shouldn’t ants still be dormant? Unfortunately, carpenter ants don’t always follow the rules. These destructive pests can become active inside your home well before the weather warms up outside, and that’s a problem. At Atlantic Pest Control, we know carpenter ants are one of the most common and damaging pests we deal with in Maine, and early activity is a red flag that shouldn’t be ignored.
Carpenter Ants Are Already Living Inside Your Home
The most important thing to understand is this: if you’re seeing carpenter ants inside your home in February or March, they’re not coming in from outside. They’re already living in your walls, attic, or another hidden area of your home. Carpenter ants establish colonies inside wood, and once they’re settled in, they can remain active year-round in the warmth of your home. While outdoor carpenter ant colonies go dormant in winter, indoor colonies stay active because your home provides consistent warmth and protection from the cold.
Why You’re Seeing Them Now
Carpenter ants are most active at night, so you might not notice them during the day even if they’ve been in your home for months. However, as their colony grows, activity increases. You’re more likely to see ants during late winter because the colony is expanding and ants are foraging for food to sustain the population. Additionally, warmer days in late February and March can trigger increased activity even if it’s still cold outside. Central heating also keeps indoor colonies active and thriving.
What Carpenter Ants Are Doing to Your Home
Unlike termites, carpenter ants don’t eat wood – but they do hollow it out to create their nests. Over time, this can cause serious structural damage. Carpenter ants prefer moist or damaged wood, which is why they’re often found in areas like window sills and door frames, roof eaves and soffits, attics with moisture problems, and areas around plumbing or leaky pipes. If you’re seeing carpenter ants in your home, it’s a sign that a colony is actively tunneling through wood somewhere in your structure.
How to Tell If You Have a Carpenter Ant Problem
In addition to seeing live ants, there are other warning signs of a carpenter ant infestation. Look for small piles of sawdust-like material (called frass) near wooden areas, a faint rustling sound inside walls at night when the ants are most active, and winged ants (swarmers) in spring, which indicate a mature colony ready to reproduce. Seeing even a few carpenter ants inside your home during late winter is enough to warrant a professional inspection.
Why You Shouldn’t Wait Until Spring
Many homeowners think they can wait until spring to address carpenter ant problems, but that’s a mistake. The longer carpenter ants are active in your home, the more damage they cause. Late winter is actually the perfect time to take action because the colony is still contained and hasn’t started swarming yet. Our team can locate the nest, eliminate the colony, and prevent future infestations.
