Termites are crafty little bugs. They are very good at what they do because they have lots of on the job training, millions of years worth. They have been around a long, long time and termites own the territory. We humans are intruders upon their space.
The Formosan Subterranean termite is native to East Asia and was introduced to the US probably around 1945 following the end of World War II. It is considered to be the most destructive insect pest of wood and other cellulose materials throughout New Orleans, Southeast Louisiana, and many other parts of the country.
