Sheet rock repair found termite damge - how can I repair this?
I bought the house knowing it had past termite damage but Terminex said none were active and they had been treating the house for several years. So 6 years later I need to replace a section of wallboard under the air conditioner and I find wrecked boards. I don't have a clue what to do. I can't, of course, fix more than this area, but should I get some insulation and stuff it in there or what?
The wood is mostly sawdust with supports on the side and bottom that seem in decent shape. The damage looks old and digging around produced no termites. Here are the pictures.
Any suggestions would be appreciated.
