Citronella Ants in Southern Maine:
Identification, Prevention, and Control
Learn how to identify citronella ants common across Cumberland and York Counties. I cover everything from signs in your home to prevention steps tailored to our coastal and wooded Southern Maine environment. Serving Naples, Raymond and surrounding towns.
What Are Citronella Ants?
Citronella ants, scientifically known as Lasius claviger, are small yellow ants common in Southern Maine. Workers measure only about 1/8 inch long and appear pale yellow to light orange brown. They earn their name from the strong citronella or lemon scent they release when crushed or disturbed.
These ants are not polymorphic. All workers stay roughly the same small size. They nest in soil near foundations, under stones, logs, or mulch and tend underground aphids for honeydew. Colonies can produce large numbers of winged swarmers that appear indoors in late summer or fall. They are one of several ant species found in southern Maine. Browse the ant pest library to see other species common to the area.
For detailed species information see the University of Maine Cooperative Extension guide on ants in Maine.
Signs of Infestation
Look for these clear indicators:
- Small pale yellow ants trailing indoors near baseboards, windows, or basement cracks
- A distinct lemon or citronella smell when ants are crushed
- Large numbers of winged ants suddenly appearing indoors during August through October
- Ants clustering around moist areas or cracks in foundations and floors
- Tiny yellow ants emerging from soil near the house after rain
In Southern Maine locations such as Naples or Raymond these ants often nest in moist soil right against foundations and enter homes through tiny gaps seeking shelter or moisture.
Risks in Southern Maine
Citronella ants cause no structural damage and do not spread disease. They rank strictly as a nuisance pest that can create unpleasant odors and produce large indoor swarms in fall. In humid wooded or coastal yards they thrive near foundations and may highlight moisture issues in basements or crawl spaces. My low-impact Integrated Pest Management approach follows best practices from the Penn State Extension guide on citronella ants and keeps your family and pets safe while solving the problem at the source. Citronella ants are often mistaken for odorous house ants due to their similar size, though the distinctive lemon scent sets them apart.
Prevention Tips
Simple steps that work well in our climate:
- Seal cracks and gaps around foundations, windows, doors, and utility lines
- Reduce moisture by fixing leaks and improving drainage near the house
- Keep mulch, leaves, and debris at least 12 inches away from foundations
- Remove stones, logs, or boards that provide nesting shelter
- Inspect and dry any damp areas in basements or crawl spaces
These habits prove especially useful in York County towns like Standish, Windham, or Sebago where moist soil and wooded lots are common.
Professional Treatment
When prevention is not enough I provide targeted, low-impact control. I locate the nests in damp wood or soil near foundations, use low-toxicity baits and precise barriers, and avoid unnecessary broad spraying. Treatments are customized for each property. A single family home in Lyman may need different focus than a business in Saco. I handle the entire process myself from start to finish.
If citronella ants are finding their way indoors, my ant control services in southern Maine offer targeted treatment to locate nests and keep them out for good.
Frequently Asked Questions

No. They create no structural damage and do not spread disease. They remain a simple nuisance that produces odors and fall swarms.
Most jobs see major improvement within 1 to 2 weeks and full resolution in 1 to 4 weeks depending on colony size. I stay until it is solved.
