Workers feeding above ground construct tunnels or tubes made of soil and wood particles and salivary secretions. These tubes protect the workers and retain moisture in the nest. Biology differs from the more common subterranean termite because it does not nest in the ground and thus requires a different, more expensive treatment approach. Termites are medically harmless. Worker termites tunnel into structural timbers and other sources of cellulose on which they feed.
Termites are harmless to man and animals although soldier termites can bite.
They occur throughout Texas, but are more prevalent in coastal regions. See also How to Select a Termite Control Service and Household and Structural Pests.
