Control of Formosan Termites

Formosan Termites are the most destructive termite species in the US and are found in the Gulf Coast states, along the eastern seaboard north to North Carolina, as well as in Tennessee, California and Hawaii. Formosans are a subterranean species that is about ½ inch in length, including its wings. Originally from China, these termites are among the most aggressive in attacking wood.

Habitat

They build earthen-shelter tubes to protect themselves from low humidity and predators. The tubes are usually ¼ to 1 inch wide and can be found in crawl spaces and inside and outside slab foundations. Cracks in concrete foundations and open voids in concrete block foundations are hidden avenues of entry for these insects.   To identify them, see our pictures of Formosan termites.

Health Risks

Termites do not sting or bite and are not known to carry or transmit diseases.

Property Damage

Termites cause damage by boring holes and tunnels throughout wood. Most species of termites have microscopic, one-celled animals called protozoa within their intestines that help to convert wood into food for the colony. Often, wood must be removed to see the damage; however, galleries can be detected by tapping the wood every few inches with a screwdriver handle. Damaged wood sounds hollow, and the screwdriver may break through the wood if termites are present.

Prevention

Destroy shelter tubes to interrupt access to wooden substructures and to open colonies to attack from natural enemies such as ants. Ventilate crawl spaces and install a moisture barrier. Remove infested wood and tree stumps and do not store fire wood or lumber on the ground next to your home. Water from downspouts and gutters should divert water away from the structure.
