Formosan Subterranean Termites, sometimes also called ground termites are a type of introduced subterranean termite common in warmer climates such as Hawaii. This species of termite was probably introduced to the Hawaiian islands via infested wood and has been active in Hawaii for over 100 years. In Hawaii, they are one of the most economically significant invasive species costing well over $150 million a year in structural damage to home and commercial property owners.
Where They Live
The Formosan termite nests and builds colonies inside the ground, and will invade properties via wood to ground contact using mud tubes. Similar to other termite species they digest cellulose based materials such as wood. Formosan termite queens can produce over 1,000 eggs a day. New colonies are created when the winged termites fly out and pair with other winged termites.
Because Formosan termites destructive power is done in stealth and silence, building owners will often discover Formosan termite infestations during renovations. Additionally, floors or walls damaged by a termite infestation can sag or show other signs of duress.
Underground colonies average over two million members, with large colonies exceeding ten million individual termites. In Hawaii, properties built over large colonies have been destroyed in only several years.
How To Defend Against The Formosan Termite
The best defense against the Formosan termite and other termites in general, is simply prevention. If an infestation has already occurred, than early detection and fumigation treatment is the second best option.
