Subterranean Termites: There are about 2,800 known species of Termites throughout the world. In the United States, Subterranean Termites (aptly named because they build underground nests), including Eastern, Western, Desert and Formosan Subterranean Termites are a concern in every state except Alaska. In Florida the Eastern and Formosan are most common.

Subterranean Termites can be extremely destructive because they tunnel their way to wooden structures (like your home) to obtain food. Termites all share an appetite for wood and other cellulose-containing materials. Given enough time, they may feed on the wood until little is left but non-supportive remnants.

A Termite infestation is no reflection on the property owner. Because termites live and travel in the soil beneath a home, even the most beautiful, well-kept homes are vulnerable to damage. The best way to ensure your home remains Termite-free is to hire a licensed and trained pest professional (such as… Anti-Pesto) who will protect your home using the most effective products available. In fact, if Termites are infesting one structure in a neighborhood, the whole neighborhood may be at risk. As you can see by the USDA Termite Homeowner map below, all of Florida is considered to be “very heavy “risk area.

SWARMING

Easter Subterranean Termite swarming may occur in the early spring, but other, smaller swarms may occur throughout the summer and into the fall. Eastern Subterranean termite growth can be slow, and it may take as many as four to 10 years before swarmers are produced. Swarms may occur in the morning to early afternoon on a warm, humid day, especially after a rain, and may be extensive in a neighborhood. Swarms in interior of a home almost always mean that the structure is infested and a pest professional should be contacted for an inspection. Interior swarms will many times be found near windows, doors, etc., as the flying reproductives are attracted to lighted areas.

Formosan Subterranean Termite swarmers are larger than native species. They may swarm in the evening and later in the year (May-June), and are strongly attracted to lights. You may see the swarmers near the porch light, windows, doors, etc. Swarms may come from an attic space into the home through vents/openings in the ceiling, as these termites are attracted to lights.

Termites are most visible to homeowners when they’re swarming. Still, without protection termites can damage structures throughout the year. In fact, you could have an active termite infestation in your home and never see a swarm.
