Formosan subterranean termites are considered the most economically devastating and aggressive species of termite, especially in the United States.
Similar to other types of subterranean species, Formosan termites also feed on stuff that is cellulose based. Moreover, due to their big colony, these termites usually invade large amounts of wood more rapidly. For that reason, Formosan termites are dubbed as “super termites”.

What Do Formosan Termites Look Like?
Like other species of termites, these species of termites are categorized in three castes: swarmers or winged reproductives, workers, and soldiers.
Soldiers have a big orangish-brown elongated-shaped head and are off-white in color. These termites also have a curved jawbone which they can utilize to protect their colony and themselves.
- Swarmers or Winged Reproductive
Swarmers or winged reproductive are 12mm to 15mm or about ½” in length and yellowish-brown. Moreover, they have transparent wings which are concealed with small hairs.
The Formosan termite workers, on the other hand, look much like the workers of other termite species. Meaning to say, they are about ¼” or less in length and are cream or white.

Where Do They Live?
Formosans tend to live in big underground colonies and even in buildings and boats. They are also building a nest in the walls of your property. On the other hand, they attack structures directly from the soil over the wood to ground contact. Or using mud tubes, they made using soil as their material.
