Ants in Southern Maine:
Identification & Prevention
Ants are among the most common structural pests in southern Maine, invading homes and buildings for food, water, and shelter.
In our region's forests, coastal areas, and urban spots, species like Carpenter Ants thrive in moist wood, while Pavement Ants nest under sidewalks. These social insects from the Formicidae family form large colonies and can quickly become a nuisance.

Common Ants in Southern Maine






Why Do Ants Invade Structures in Southern Maine?
In southern Maine’s temperate climate, ants enter structures during spring thaws or fall to escape cold. They’re drawn to crumbs, spills, pet food, and moisture from leaks. Foraging workers follow pheromone trails, leading colonies indoors. Species like Carpenter Ants target damp wood, while Odorous House Ants seek sugary residues in kitchens. Overwintering in walls or foundations is common in areas like York and Cumberland counties.

Identification Tips for Ants in Southern Maine
Look for segmented bodies with three parts (head, thorax, abdomen), elbowed antennae, and narrow waists. Sizes vary: small (2-4mm for Pavement) to large (6-12mm for Carpenter). Colors range from black/reddish (Carpenter) to brown (Odorous). Signs include trails, small soil mounds, or sawdust-like frass near wood. In Maine, winged swarmers appear in spring.
- Check for odor—Odorous House Ants smell like rotten coconut.
- Observe behavior—Acrobat Ants curve abdomen upward.
Behavior & Habits of Ants
Ants are social, living in colonies with queens, workers, and males. They communicate via pheromones, forming trails to food. In southern Maine, they nest outdoors but invade for resources. Activity peaks in warmer months; some overwinter indoors. Colonies can relocate quickly if disturbed.
Risks & Threats from Ants
While most are nuisances, Carpenter Ants damage wood structures. European Fire Ants sting, causing pain/swelling. Contamination of food is common; some carry bacteria. In Maine, property damage from nesting is a key concern.
- Health: Bites/stings for sensitive individuals.
- Property: Tunneling weakens beams.

General Prevention Tips for Ants
- Reduce attractants by keeping surfaces clean, storing food in sealed containers, and fixing leaks.
- Seal cracks around doors/windows.
- Trim vegetation away from buildings.
- For safe management, consult a professional.
