Sugar Ants (Odorous House Ants)
Tapinoma sessile
Sugar ants are small, dark brown to black ants measuring 1/16 to 1/8 inch in length. Often called odorous house ants, they emit a distinctive rotten coconut smell when crushed. These persistent pests are attracted to sweet substances and can quickly establish large colonies with multiple queens inside your home.
Habitat & Behavior
Sugar ants nest in a variety of locations both indoors and outdoors. Outdoors, they nest under rocks, in mulch, beneath pavement, and in wall voids. Inside homes, they prefer warm, moist areas near food sources like kitchens and bathrooms. They commonly nest behind walls, under floors, in insulation, and around water heaters or heating systems.
Signs of Infestation
- Trails of small black ants leading to food sources, especially sweets
- Distinctive rotten coconut or blue cheese odor when ants are crushed
- Ants appearing in kitchens, bathrooms, and pantries, particularly near water
- Increased ant activity during rainy weather when outdoor nests flood
- Multiple ant trails originating from different entry points
Health & Property Risks
While sugar ants don't pose significant health risks, they contaminate food supplies and surfaces as they forage through garbage and unsanitary areas. Their presence can indicate sanitation issues or structural problems providing entry points. Large colonies can be extremely difficult to eliminate without professional treatment, and their multiple nesting sites make DIY control largely ineffective.
Prevention Tips
- Store all food in airtight containers and clean up spills immediately
- Wipe down counters with vinegar solution to eliminate ant pheromone trails
- Seal cracks and gaps around windows, doors, pipes, and utility lines
- Fix leaky faucets and eliminate standing water sources
- Take garbage out regularly and keep trash cans clean
- Trim vegetation away from your home's exterior and foundation

Other common ants you might encounter
Carpenter Ants
Carpenter ants are large, black or dark-colored ants measuring 1/4 to 1/2 inch in length. Unlike termites, they don't eat wood but excavate it to create nesting galleries, leaving behind piles of sawdust-like material called frass. These destructive pests are one of the most common wood-damaging insects in North America.
Fire Ants
Fire ants are small, aggressive red or reddish-brown ants measuring 1/8 to 1/4 inch long. They're known for their painful, burning stings that leave raised, white pustules on the skin. These invasive pests build distinctive dome-shaped mounds in lawns and open areas, with colonies containing up to 250,000 workers.
Pavement Ants
Pavement ants are small, dark brown to black ants measuring about 1/8 inch in length with distinctive parallel grooves on their heads and thorax. These common household pests get their name from their habit of nesting under pavement, concrete slabs, and along sidewalks. Colonies can contain thousands of workers and multiple queens.
