Carpenter ants in Michigan can become a costly problem if you ignore them. These large ants are not just a nuisance; they can damage your home.
They hollow out wood to make nests, which weakens beams and trim over time. As fall nears, they move deeper indoors for warmth and food. That makes winter prevention especially important.
From Lansing to Ann Arbor, homeowners face the same fall task: keep carpenter ants out before the snow. Unlike termites, carpenter ants don’t eat wood, but their tunnels still cause damage and costly repairs. Learn the signs now to protect your home through winter.
If you’ve noticed sawdust piles or winged ants inside, you may already have an infestation. Before winter arrives, it’s smart to take preventive steps or call a trusted pest control company, such as Pest Pros of Michigan.
Key Takeaways
- Carpenter ants damage wood by tunneling, not eating it.
- Signs include sawdust, winged ants, and hollow-sounding wood.
- Moisture problems and nearby tree stumps raise the risk.
- Professional pest control is the most reliable way to prevent winter damage.
Understanding Carpenter Ants in Michigan Homes
Carpenter ants often go unnoticed at first. The black carpenter ant (Camponotus) is common in Michigan. Workers carve smooth galleries in damp or decayed wood. Homeowners usually see frass, or fine wood shavings, near baseboards or window sills.
Unlike termites, carpenter ants chew softened wood but don’t eat it. Due to this difference, professionals employ different treatment methods. An infestation may start in a stump outside and then spread into wall voids or crawl spaces. Seasonal inspections help stop this early.
In Michigan, carpenter ants stay active indoors all year, with spikes in spring and fall. You may see workers foraging at night, especially around pet food or other steady food sources.
Common Signs of Carpenter Ant Infestation
Spotting carpenter ants early prevents costly damage. Watch for these signs:
Look for sawdust-like frass near windows, doors, or baseboards. It builds up as ants dig tunnels. Winged ants indoors, often in late summer, mean the colony is mature and nearby.
You may also hear faint rustling inside wall voids. Ants use strong mandibles to tunnel through wood, and in quiet rooms, you can listen to the sound. Damaged wood with smooth, hollowed-out galleries is another red flag.
If you see multiple signs of carpenter ants, it may mean a nest has already taken hold indoors. Satellite nests can spread to other rooms, making the problem hard to control without professional help.
Why Carpenter Ants Target Michigan Homes
Carpenter ants in Michigan homes prefer damp, decaying wood. Leaky roofs, clogged gutters, and poorly ventilated crawl spaces create perfect conditions. Window sills and door frames that hold moisture also attract nesting ants.
Tree stumps near the house often serve as the original nesting site for ants. Over time, they expand indoors and spread the problem. Older homes with untreated wood or poor sealing are especially vulnerable.
Food sources also draw ants inside. Worker ants forage for crumbs, pet food, or sweet liquids. Once they find a reliable source, they create scent trails back to the carpenter ant colony. This foraging behavior explains why even clean kitchens can experience an ant problem in the fall.
DIY Ant Control vs. Professional Solutions
Many homeowners attempt DIY fixes, such as using ant bait and store-bought sprays. Baits may reduce foragers, but they rarely reach hidden nests. Sprays can kill what you see, but may drive ants deeper into walls and worsen the problem.
The challenge lies in finding the actual nesting sites. A carpenter ant colony can extend through multiple areas of a home, with satellite nests hidden in damaged wood or behind insulation. Unless you deal with the source, the carpenter ant problem will persist.
Professional pest control delivers lasting results. A licensed exterminator checks for signs, finds nests, and applies targeted treatments. At Pest Pros of Michigan, we use proven products and strategies for Michigan homes to deliver safe, effective results.
Seasonal Timing: Why Winter Prevention Matters
As winter nears, carpenter ants move deeper indoors. Workers maintain the nest and protect the queen. Once settled, the colony can ride out the cold and come back strong in spring.
If you wait until spring, damage may already be severe. Treating in the fall prevents the colony from spreading. Winter prevention also cuts the risk of satellite nests in walls or attics.
MSU Extension advises homeowners to address moisture problems first, since carpenter ants thrive in damp conditions. Fixing leaks, sealing gaps, and storing firewood away from the house are practical steps.
For complete protection, pairing these efforts with professional pest management is the most effective strategy.

FAQs
What is the difference between carpenter ants and termites?
Carpenter ants dig nests and leave sawdust. Termites eat wood and often leave mud tubes. Termite damage is usually more hidden and severe.
How can I tell if I have a carpenter ant infestation in my home?
Look for sawdust-like debris, called frass, winged ants indoors, or faint rustling in walls.
Can I get rid of carpenter ants on my own?
DIY steps may kill what you see, but hidden nests remain. Because colonies often build satellite nests, professional treatment is the most reliable way to solve the problem.
