Subterranean termites using mud sheathing to encase lumber

WDO inspector Alex Stewart reported finding a large subterranean termite infestation that was strikingly different in appearance, at a house in the Tuolumne City area of Tuolumne County, California.

The termite mud “tubes” were actually more of a mud sheathing, spreading over the surface of the lumber.

There was a moisture condensation pipe venting into subarea, dripping very slowly, adding some additional moisture to the soil. This structure was build in 1965. Subs and dry rot were serious issues here.
