my first house had them. terminix treated it and i paid something like 100 bucks a year for them to do it every year. i never saw any damage from them. now carpenter ants, those fuggers did a number on the rim joists behind my front porch. when i tore it off they fell out of there by the handful i sprayed the schit out of them with something and patched the bad spots with pressure treated lumber and put the new porch on. house is still standing and so is the porch and thats 25 years ago.
