Termites, active all across Texas, from Amarillo to Midland, across the Dallas/Fort Worth area and down to San Antonio, Houston and Corpus Christi, cause billions of dollars in damage each year. They primarily feed on wood, but also damage paper, books, insulation, and even swimming pool liners and filtration systems. They can injure living trees and shrubs, but more often are a secondary invader of woody plants already in decline. Besides the monetary impact, thousands of winged termites emerging inside one’s home, coupled with the thought of termites silently eating on your largest financial investment, are an emotionally trying experience.
Spring is when large numbers of winged termites, known as “swarmers,” typically emerge inside homes. In nature, termites swarm to disperse and start new colonies. Triggered by warmer temperatures and rainfall, the winged termites emerge from the colony and fly into the air. Of course, the discovery of winged termites indoors almost always indicates an infestation requiring professional treatment.
Subterranean and Drywood termites are the most prevalent termites known to damage homes in Texas; however, Formosan termites also have been identified in Texas. In fact, Formosan termite infestations have been confirmed in 30 counties in the eastern half of Texas, including Harris County.
Termites usually swarm on warm days following a rainfall, but swarms also may occur during the winter in heated buildings. The Eastern Subterranean Termite typically swarms from February to May. This species typically swarms in the morning hours, while the Formosan Termite swarms at night during the late spring. Southeastern Drywood Termites also swarm at night in the spring. The Dark Southeastern Subterranean Termite swarms during the day in March and June. The Arid-land Subterranean Termite swarms in daylight in the spring and fall. The Tropical Rough-Headed Drywood Termite swarms at night from April to July, and the Western Drywood Termite swarms during the day in summer. Unfortunately, there is almost no time during the year that termites don’t swarm, as the Light Southeastern Subterranean Termite swarms during the day in the fall.
Often there is no visible indication that a home is infested, as infestations can go undetected for years, hidden behind walls, floor coverings, insulation, and other obstructions. Termite feeding and damage can even progress undetected in wood that is exposed because the outer surface is usually left intact.
Termite-damaged wood is usually hollowed out along the grain, with bits of dried mud or soil lining the feeding galleries. Wood damaged by moisture or other types of insects (e.g., carpenter ants) will not have this appearance. Occasionally termites bore tiny holes through plaster or drywall, accompanied by bits of soil around the margin. Rippled or sunken traces behind wall coverings can also be indicative of termites tunneling underneath.
Ridding a home of termites requires special skills. A knowledge of building construction is needed to identify the critical areas where termites are likely to enter. Many of these potential points of entry are hidden and difficult to access. Experts estimate that termites damage more than 600,000 homes in the United States annually. In fact, termites cause more damage to U.S. homes each tornadoes, hurricanes, wind and hail storms combined. Unlike weather-related damage, termite damage is not covered by homeowners insurance.
According to Termite Infestation Probability Zones (TIP Zones), eastern Texas is located in TIP Zone #1 (heavy to moderate), which means the potential for termite damage is considered significant. Areas with higher probabilities for termite activity require more termite control measures to meet International Residential Code building standards for new homes than areas with less frequent activity.
In Texas where termites are very active and widespread, it is essential to maintain an effective termite prevention and control program.
