Termites can live outside or inside your home. They make mud tubes to move from one place to another.

Inside: Mud tubes are a telltale sign that termites, which eat wood and other cellulose, are in the home.

Outside: Termites can be seen if they swarm or leave behind castings of fecal matter or discarded wings.

Termites are often found inside a building because they can't survive in freezing climates and it is difficult for them to get back into a house once it gets cold outside. But termite infestations often occur indoors in warmer climates as well, when people fail to prevent the pests from entering their homes and offices through doors, windows, water pipes and other openings.
