It is estimated that termites cause an average of 5 billion dollars annually in the United States. Approximately, 4 million homes in the United States face the risk of infestation every year. For each individual home, repairs can range from $250 to $30,000 depending on the type of wood, the amount of damage in the home, and what kind of wood members they are. Keep in mind, subterranean termites cause costly repairs since they live in the soil and damage the foundation first.
