Carpenter Ants questions from Kearny Mesa homeowners
Are carpenter ants as damaging as termites in Kearny Mesa?
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 Kearny Mesa?
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.
