Which of the following is a common sign of a termite infestation?

Mud tubes are a common sign of a termite infestation, particularly in Subterranean termites. These tubes are constructed by the termites using a mixture of soil, wood, and saliva, serving as protective passageways to navigate between their underground colonies and above-ground food sources, typically wooden structures. The presence of mud tubes can often indicate an active termite colony, as they create these tunnels to protect themselves from open air, which can be harmful to them.

In contrast, beehives are associated with bees and do not indicate termite activity. Spider webs are created by spiders and do not signify termite infestations or activity. Ant trails may indicate an ant problem but have no direct correlation with termite presence. Recognizing mud tubes is crucial for pest control professionals, as it enables the identification and management of termite infestations early to prevent extensive damage to structures.
