Termite Damage Vs. Wood Rot
Dry rot caused by fungi and termite damage can occur due to a common reason: contact with the soil. This can happen with foundation cracks, in particular. Ironically, dry rot is usually caused by wood having too much contact with moisture; it's the fungi that transport the water to drier spots, making the wood "dry rot." Because subterranean termites live below the surface, foundational cracks give them an opportunity to find a fresh, readily available food source in wooden structural supports.
