Subterranean Termites
Subterranean termites on another hand live in soil and needs moisture for their existence. They are majorly responsible for causing damage to the buildings and its contents. They build underground colonies or nests and form mud-wall tunnels or runways (tubes) that serve as safe shelter for their movements. Many times they build nests near ground in stumps of dead trees or create colonies within the form of dome shaped mounds on the ground.
It is by these mud wall tubes in which they manage direct contact along with the soil for meeting their moisture needs. These mud walls also create conditions of darkness that is fundamentally required for their survival. The termites enter the building by foundations or from ground adjacent to buildings and advance upward by floors destroying everything which comes inside their reach. They might also enter the building by cracks in masonry and joints or cracks in floors in contact along with ground. Termites eat celluloses materials such as grass, wood, etc. and also attack materials such as leather, plastics, furniture, rubber, furnishings; clothing, stationery and etc.
