While renovationg a bathroom I began to uncover termites in my ceiling beams....and then the roof rafters.
I am vigorously removing wood within reasonable proximity of the damage to see how far its gone....this spring I will have to go up in the attic for a more thorough investigation. Obviously come this week I will call the pest control folks.
I have not found any of the excrement but this was because the old ceiling was removed and we never thought of looking as there were no signs of termite issues then. What I do find is a lot of what appears to be their "termite sawdust" when I burst through the tunnels with the chisel and hammer. No signs of the actual termites either. I remember finding some similar damage in one of the basement joists but it appears to be old, ie, no recent activity.
I will have to replace the rafters in question but I paranoid that if I dont do it now, they could spread as spring comes. And with three roof rafters in a row having been infected, it does raise some structural concerns.
We had a fella replace the shinlges about 7 years ago....and if you notice there is a new pressure treated board up there at the base....which makes me wonder if this fella was replacing a termite infected piece, and didnt realize they were underneath.....OR....if they began to infect later.
MY QUESTIONS TO YOU ALL ARE THUS:
--Based on my description and the photos, how can I tell if the damage is recent or in the more distant past?
--are there any ways beside finding bodies or excrement that would let me know?
They appear to be somewhat confined to
