Termites / PTL Lumber

Mud tunneling present on a prior WDI (Termite) repair.

First time that I have found a Mud Tunnel and activity thru PTL Lumber.

I’ve heard of such things, but rare. The termites either go deep enough to avoid the chemicals, or they find a vein to move through it.

Not beating you up for the photos, I would have taken a few more. I’ve never actually seen it live. :frowning:


Termites were in the Beam above.

Not sure if they followed the Nail Up or the Nail Down.

Either way WDI treatment was recommended (NPMA-33).

It was an interesting scenario.
