As the weather warms up in spring, it’s not just the sun that emerges – termites also make their presence known. Subterranean termites, the most common type in the U.S., reside mainly in the soil. Jim Fredericks, National Pest Management senior vice president and board-certified entomologist, explained in a recent interview that the shift from winter to spring, with rising soil temperatures and increased moisture, triggers termite swarming. These swarms consist of winged termites searching for a new colony, occurring annually as part of the termite growth cycle.
The onset of spring rainstorms heralds the arrival of termites, even in regions accustomed to cold winters. While weather is a factor in termite swarming, predicting the exact timing remains elusive. However, certain regions, such as those stretching from Chicago to New York and including Indiana and Ohio, are forecasted to experience wetter than usual springs, according to weather.com meteorologist Dina Knightly. Conversely, some parts of the Southwest can expect drier conditions.
Recognizing termite infestation is crucial, as these pests cause over $6.8 billion in damages annually in the U.S. Swarms, both indoors and outdoors, are often mistaken for flying ants. Look out for mud shelter tubes, which are soil-colored tunnels that termites use to navigate from the ground to structures. Damaged wood is a clear sign of infestation, as well as difficulties in opening doors and windows due to termite-induced moisture damage.
Preventing termite invasions involves various measures. Frequent checks for sources of moisture, such as leaks and flooding, are essential, as termites are attracted to damp wood. Redirecting rainwater away from the foundation, ensuring wood structures don’t touch the ground, and maintaining an airtight home are all effective strategies. Consulting pest control professionals or the local extension service for further advice can help safeguard your property against these destructive pests.
