Common Ant Problems in Michigan Homes
Michigan homeowners deal with ant pressure every spring and summer. The mild winters in Oakland and Macomb County allow ant colonies to persist year after year, and warming temperatures in April and May send forager ants searching for food and moisture inside homes.
The most important step in effective ant control is identifying the species — because the treatment approach varies significantly between carpenter ants, pavement ants, and odorous house ants.
Carpenter Ants
Carpenter ants are one of the most common structural pests in Michigan. Unlike termites, they don't eat wood — they excavate it to build galleries for nesting. A large carpenter ant colony inside your walls, attic framing, or window sills can cause real structural damage over time.
- Large black or bi-colored ants (typically ¼ to ½ inch)
- Often found near moisture-damaged wood — leaky windows, roof edges, deck boards
- Forager ants most visible at night
- Frass (sawdust-like debris) is a key sign of active nesting
Treatment can target satellite colonies inside the structure as well as the parent colony outside, using methods appropriate to the infestation and property.
Pavement Ants
These smaller brown ants nest under concrete slabs, along foundation edges, and in cracks in driveways or patios. They commonly invade kitchens through expansion joints and gaps around plumbing. While they're not structurally damaging, they can contaminate food and are difficult to eliminate without addressing the colony.
Odorous House Ants
Small, dark brown ants that emit a distinctive odor when crushed — often described as rotten coconut. These ants form large multi-queen colonies that are notoriously difficult to control with over-the-counter sprays, which often cause the colony to "bud" and split into multiple locations.
Ant Treatment Approach
Effective ant control goes beyond treating only the ants that are visible. A professional service may include:
- Inspection to identify species and locate entry points and nesting areas
- Targeted interior treatments where needed
- Exterior perimeter barrier application
- Recommendations for moisture correction or structural sealing when applicable
For recurring infestations, scheduled maintenance may be available to help keep ant pressure under control throughout the season.
Why DIY Ant Control Usually Fails
Over-the-counter ant sprays kill forager ants on contact but rarely reach the colony. For species like odorous house ants, repellent sprays can actually worsen the problem by causing the colony to spread. Professional treatment uses non-repellent products and baits that workers carry back to eliminate the source.
