What do Formosan termites not require as long as there is a moisture supply?

Formosan termites have a unique adaptive capability that allows them to thrive in environments where other termite species may struggle. They do not require constant contact with the soil as long as there is an adequate supply of moisture available. This characteristic distinguishes them from many other termite species, which typically need direct access to soil for moisture and to build their nests.

As long as they can access moisture from wood, other organic materials, or their environment, Formosan termites can establish their colonies above ground, which facilitates their invasive behavior in structures and urban areas. This ability allows them to exploit a wide range of environments, thereby increasing the risk of infestations in buildings.

Other aspects such as direct exposure to sunlight, access to food sources, and wood for nesting still play roles in their survival, but the critical factor that allows them flexibility regarding soil contact is their moisture adaptability.
