Subterranean Termite Damage Revealed

Most termite damage is invisible because termites are only interested in chewing through wood. Subterranean termite damage is no different, but they way they attack your home is very different from the behavior of drywood termites. Subterranean termites live underground and venture out only to feast on your home. They often build mud tubes up the side of the cement foundation of your home. These tubes become subterranean termite highways from the underground colony to the wood of your home.

To the untrained eye, wood on the exterior and interior of your home may appear sound, such as in the photo below. Because this 2 x 6 piece of wood was removed from a home while we were in the process of repairing subterranean termite damage, we knew there was damage inside of it.

Subterranean Termites Inside

Subterranean termites are chewing their way through this wood. Can’t see them, can you?

Without much effort we pulled off a strip of the outer layer of the 2 x 6 to expose the damage inside.

There was so much rot and damage a mere 1/4″ from the wood surface that the subterranean termite trail was clearly visible to our trained eyes.  If you have a difficult time identifying the trail, look at the image below.

As we continued pulling out termite damage, we came across this well-chewed piece of wood buried deeply inside of a wall. This wood shows the typical chew pattern of subterranean termites. They tend to attack the wood between the growth rings. Termites did such a good job of destroying this wood, it crumbled as we pulled it out. It was a challenge to find a large enough chunk to photograph.

Please Note

No houses were harmed in the process of taking these photographs. Termite damaged wood was removed and replaced with sound wood to restore the structural integrity of the home. The subterranean termites, however, were greatly harmed in the process and their colony decimated. We make no apology.
