Any break or protrusion into the structure can be an avenue for termites, so any pipe or other object that extends past the concrete can be their entrance.

This was an easy entrance for the termites and once in they usually don’t leave without taking a bit of your home for food. So what do you look for:

1. Any mud tube/tunnel on the outside foundation wall.
2. Any suspicious dirt on the ceiling, small hole with dirt around it.
3. Drop Tubes inside the homes.
4. Baseboard that looks crinkled, subterranean termites usually run with the grain of the wood.
