How to get rid of carpenter ants in Coronado, CA
Carpenter ants nest in damp or damaged wood, so San Diego homes with roof leaks, old plumbing, or poor drainage see them most. They don't eat wood like termites, but they hollow out galleries to nest and weaken framing over time.
What you're dealing with in Coronado
The black carpenter ant and a red-and-black variety are the common San Diego types, both large at a quarter to half an inch.
Coronado homes sit in salt air and marine humidity 24/7, ideal conditions for drywood termites, brown widows under stucco overhangs, and roof rats in mature palms. The pre-1950 Spanish Colonial and Craftsman stock through the Village and along Ocean Boulevard needs annual termite inspections, not biennial.
Why carpenter ants show up here
Pacific Beach, Point Loma, and Ocean Beach's marine humidity keeps wood trim damp longer, which is exactly what carpenter ants look for. Older beach cottages with original eaves and porch wood give them soft, moisture-touched framing to nest in.
How to get rid of carpenter ants: step by step
- Find and fix the moisture source Carpenter ants need damp wood. Track down roof leaks, plumbing drips, or bad drainage and dry the wood out first.
- Follow the trail at night They forage after dark. Watch where the ants travel to spot the nest entry, often behind a wall or under a window.
- Trim branches touching the house Cut back tree limbs and shrubs that bridge to the roof or siding, since ants use them as a highway indoors.
- Move firewood and wood debris away Stack firewood off the ground and away from the foundation, and clear old stumps or damp lumber near the house.
- Seal entry gaps Caulk cracks around utility lines, window frames, and the foundation to cut off the routes ants use to get in.

Carpenter Ants questions from Coronado homeowners
Are carpenter ants as damaging as termites in Coronado?
Carpenter ants damage wood slower than termites since they nest rather than eat it, but a large or old colony can still weaken framing. The bigger warning is what they signal: a moisture problem in the wood that needs fixing too.
How do I tell carpenter ants from termites?
Carpenter ants are large and dark with a pinched waist and push out coarse shavings, while termites are pale, straight-waisted, and leave uniform pellets or mud tubes.
Why do carpenter ants keep coming back in Coronado?
They return when the parent nest outdoors and any satellite nests inside go untreated, or when the damp wood that drew them is still wet. Treating the nest and fixing the moisture together is what stops them.
