Some people that I ask do not know the signs of termites. Like in this photo, they make mud/excrement tunnels from the ground and up the piers to get to the wood sills. When I see these tunnels, I disturb them to flick away the dirt and sometimes that reveals the creepy crawlies. In the picture I’ve circled some of the termites so you can see what they look like. These formosan termites found on my home inspection will do serious structural damage and must be stopped.
