What is one common entry point for subterranean termites in structures?

Subterranean termites typically enter structures through plumbing penetrations. These entry points occur where plumbing pipes pass through the foundation or walls of a building. The gaps around these pipes can create pathways for termites to access the interior of a structure from the soil, which is their natural habitat. This characteristic makes plumbing penetrations a significant concern for pest control professionals, as it allows termites to go undetected while they establish colonies and cause damage.

The other options, while they may provide access points for different types of pests, are not specific common entry points for subterranean termites. Roof vents and attic spaces are more accessible for pests like birds or rodents, while basement windows present a risk primarily for exterior pests rather than subterranean dwelling insects. Understanding these entry points is crucial for effective pest management strategies and prevention measures within structures.
