The Formosan termite is an invasive species of termite that are threatening trees in the southeastern U.S., especially in Louisiana. These termites are characterized by large populations with a wide foraging range that share interconnected foraging galleries in soil. They colonize many different species of trees including live oaks, cypress and ash. Formosan termites do not consume more wood than native subterranean termites, but their large numbers cause more damage in a shorter period of time. Because they can damage buildings as well, this species of termite poses both economic and ecological threats. Because of their large numbers and wide range, soil insecticides are not effective for control of this species. Research is ongoing to determine a safe and efficient way to control populations.
