In Greensboro, ant season begins when the first warm days of March arrive and doesn't truly end until late fall. The city's trees, damp soil, rain and plentiful wooden structures give several species ideal conditions. Knowing which ant you are dealing with shapes what comes next.
Greensboro's common ants
Carpenter ants nest in moist or rotting wood. They thrive in old trees, fence posts, decks and the framing of damp houses, and often forage at night. Odorous house ants form trails to sweet foods and can nest in wall voids and under sinks. Acrobat ants raise their heart-shaped abdomens when disturbed and often nest in dead wood and insulation. Pavement ants live under slabs, patios and driveways. Red imported fire ants do occur in the region, building mounds in sunny lawns and delivering painful stings, though they are more prevalent further south and east.
The moisture connection
A carpenter ant colony usually means water has damaged wood somewhere. In the Piedmont, common culprits are clogged gutters, leaking roofs, damp window frames, pipes under bathrooms and crawlspace areas with high humidity. Mature trees close to houses in neighborhoods such as Irving Park and Fisher Park make it easy for ants to get from the tree to the roofline. A treated nest will often be repopulated unless the damp wood and nearby parent colony are addressed.
Clues worth noting
- Fine, sawdust-like frass beneath tiny holes in wood.
- Large black ants indoors at night, particularly in spring.
- Rustling or crackling in walls when quiet.
- Persistent sugar-ant trails to the kitchen, pet bowls and bathrooms.
- Winged ants appearing indoors, which can signal a mature indoor colony.
How treatment unfolds
A licensed technician begins by identifying the ant and following trails. For sugar-feeding species, baits placed along trails are the main tool, supported by an exterior perimeter treatment. For carpenter ants, the process involves locating the nest, often in a damp wall void, and treating directly with dust, foam or liquid, plus exterior treatments around the foundation and trees. Fire ants in yards call for broadcast baits and mound treatments. Fixing moisture and trimming vegetation are essential to long-term results.
Spraying trails with store-bought products usually causes colonies to fragment and return in greater numbers, so it's best to leave baits in place.
