Carpenter Ant Control in Bellingham

Identifying Wood-Nesting Ants in Bellingham Homes

These ants are relatively large, commonly measuring one-quarter to one-half inch long. They may be black or a combination of red and black. Size and color provide useful clues, but body shape and nesting conditions offer a more reliable basis for identification.

Several characteristics can help distinguish the ants or winged insects you find indoors:

• Carpenter ants: They have a pinched waist and bent antennae. Winged members of the colony found indoors are often mistaken for termites.
• Termites: Termites have straight bodies and straight antennae, without the defined waist and elbowed antennae of the ant species. The ants are far more common than termites in the Bellingham area.
• Moisture ants: They colonize wood that water damage has already softened. The larger wood-nesting species prefers damp wood but can also tunnel into sound wood.
• Odorous house ants: These are a separate species from both wood-nesting ants and moisture ants. Their presence doesn’t by itself indicate wood excavation.

Signs of an Active Colony

A mature colony often begins with a parent nest outdoors in a stump or log. Workers may move into a house and establish a satellite nest, a secondary nesting site connected to the larger colony. These nests may be concealed in wall voids, damp wood, or insulation.

Possible signs of nesting activity include:

• Sawdust-like material: Frass, the debris removed while galleries are excavated, may collect beneath beams, along baseboards, or in crawl spaces.
• Sounds inside walls: Rustling or crinkling behind drywall can indicate ants excavating or moving through a hidden gallery.
• Winged ants indoors: Their emergence inside the home can point to an active nesting issue, not occasional outdoor foraging.

Moisture problems, deteriorated wood, nearby stumps or logs, and wood-to-soil contact can make a property more suitable for nesting. An inspection should consider indoor activity and exterior conditions because treating a satellite nest without finding related activity may leave the larger problem unresolved.
