We at Merlin's have seen the colossal damage that termites can do. We have seen termites eat the support beams out of homes, the damage was so severe that the building was condemned and was bulldozed. It ended up costing the homeowner over $100,000. The home was built back in the 1800's, so the support beams were make of solid wood, but after over 100 years, the termites had eaten it so much the entire home was sagging in the middle and could have collapsed at any moment. We've seen them turn hard wood floors into swiss cheese.
