The Eastern subterranean termite is the most common termite found in North America. Subterrantean termites nest in the soil and prefer an environment with a higher moisture content and can have colonies with populations in the millions. They build mud tubes to protect themselves from drying out and predators. Unlike the drywood termite they do not expel pellets from their galleries, instead they use the pellets to put towards the construction of their mud tubes; these mud tubes consist of soil, saliva, and excrement. Although subterranean termites are typically found nesting in the soil, that doesn’t mean that they will only be found on the ground, mud tubes with active subterranean termites have been found in attic spaces.
