What key factor differentiates drywood termites from subterranean termites?

The key factor that differentiates drywood termites from subterranean termites is their habitat preference. Drywood termites typically infest dry wood and do not require contact with soil to survive, as they create colonies within the wood itself. This allows them to inhabit a wide range of wooden structures, such as furniture and wooden frames. In contrast, subterranean termites thrive in soil and require moisture, often building extensive tunnels and colonies underground. Their reliance on soil makes them more common in areas where they can access the moisture and organic material found below ground.

The differences in habitat preference are significant as they also inform the behavior and treatment options for managing infestations. Understanding these habitat preferences is crucial for effective termite control strategies, as it helps in tailoring treatments to the specific species and their unique environmental needs.
