The Formosan subterranean termite was spread to Louisiana around the end of World War II. This termite has been described as the most important structural pest of the new millennium. We are trying to determine its range.
The Formosan subterranean termite swarms in April through the middle of July. They take flight to search for mates and wood in which to begin new colonies. When swarming, most of the winged termites are found near their source, but they may fly at least 0.75 miles.
This termite spreads naturally through swarming and budding but at a slow rate. It is being spread much more rapidly by humans through the movement of infested wood across Louisiana and to other states. Termites have been moved in railroad ties, utility poles, lumber, trees, landscape timbers, sawdust, mulch, potted plants, boats, mobile homes and paper. Do not move wood or wood products from infested areas unless you are sure the material is not infested.
Do not invite termites into your home by leaving wood and moisture near your home. Wood or cellulose products that are in contact with the ground are an open invitation for termites to visit you. Keep moisture away from your house.
One of the best preventions is a yearly inspection for signs of termites. Look for mud tubes on the side of the pier or slab around the perimeter of the structure. Inspect areas where moisture is commonly found: behind showers and tubs, kitchens, utility rooms and outside faucets.
It is important to know where the Formosan subterranean termite is located in the state to help prevent its spread. You can help in this effort by reporting infestations to the LSU AgCenter and by sending several winged termites (with wings) and/or soldiers (termites with large, orange-yellow heads) for identification. Termites should be collected and placed in 100% alcohol and sent to us for identification. Please send termites to Dennis Ring, 404 Life Sciences, Department of Entomology, LSU Agricultural Center, Baton Rouge, Louisiana 70803. Include your name, location (street address or road, city, zip code) where termites were collected, parish and material or plant they were collected from. Contact your county agent for assistance in sending termites or for more information.
Help us better determine the range of the Formosan Subterranean Termite.
