What are three signs of termite infestation?

The presence of frass, mud tubes, and damaged wood are key indicators of a termite infestation. Frass refers to the wood pellets produced by termites as they consume wood, often found near their feeding sites. Mud tubes are structures built by certain termite species, particularly subterranean termites, as a protective pathway from the ground to their food source, which helps them maintain moisture and avoid predators. Damaged wood is another critical sign, especially when it appears hollowed out or exhibits visible signs of tunneling and deterioration.

Other signs listed in the incorrect options do not specifically relate to termites. For example, beehives pertain to a completely different type of insect, while spider webs indicate the presence of spiders, not termites. Fungus and mold can suggest moisture issues but do not confirm termite activity, and while damaged siding or crumbling bricks may indicate structural problems, they are not definitive signs of termite presence. Therefore, the combination of frass, mud tubes, and damaged wood provides a specific and reliable indication of termite activity.
