Subterranean Termites in Florida

Subterranean termites are the most widespread and destructive termite group in the United States. The most common wood-destroying pests among this group are the eastern subterranean, western subterranean, and Formosan subterranean termites. Termites consume cellulose, the main structural component of plant cells. Any wood material in a home is a potential food source. Termites may also damage non-wood material in search of food. They rarely show themselves in the open, and infestations can be difficult to detect until the damage becomes severe.

Subterranean Termite Habitat

Subterranean termites live underground and feed on plant materials. Winged termites are attracted to light and will swarm around doors and windows. After fluttering around for a short time, the termites break off their wings and pair off, becoming king and queen of a new termite colony. A common sign of termites is the presence of mud tubes, inside or outside of a home. Termites make these earth-colored tubes primarily as a protected runway from the earth to the wood they feed upon. These “mud tubes” protect themselves from predators and exposed air as this can dry them out.

Subterranean Termite Behaviors, Threats or Dangers

Any wood material in a house is a potential food source as termites consume cellulose. Termites are secretive, and when termite damage becomes evident, it is usually the result of a few years of infestation. The presence of swarming termites or their wings alone is a sure sign that termites are working in your home or building. Winged termites are often confused with winged ants; however, most species of ants in the house are only nuisances and, except for carpenter ants, do not damage wood. To prevent or control a subterranean termite infestation, it’s important to enlist the help of a professional termite exterminator.
