Elderly dad had them for years apparently, not sure what kind but mud tunnels everywhere. I got on amazon ordered something you poured into a 2ft deep x 2ft wide trench, dug by an out of shape 48 yo woman w a 89 yo man following close behind with a steel tape, 6 yr guarantee and it actually worked..they ate the walls, trim boards, and some things that were just sitting around..they didn't touch the joists? at all..he had them for at least 15 yrs, said if the tunnels were moist they were active, if dry dormant and leave them lest you stir them up...good luck
Thanks for the input. Sounds like subterranean termites, and that you treated solely from the ground outside of the structure. I will further research that further. Mine appear to be in the attic only. Again, thanks!
