Subterranean termites need contact with the soil and moisture to survive and live underground. They can build tunnels through cracks in concrete. Because Subterranean termites thrive on moisture, you should try to prevent water from accumulating at the foundation of your home including installing gutters, splash blocks, or downspouts. Creating an artificial slope will allow water to drain away from the structure. Humidity in crawl spaces may be reduced with proper ventilation. Secondly, sanitation is crucial. Keep trees, vines, and trellises trimmed so they are not touching the structure, and never pile or bury extra wood scraps or lumber near the home.
Lastly, termite baiting is a fairly simple process and can be used as a tool to monitor termite activity early on before infestations flare up. The termites feed on the bait and take the bait back to the colony to kill the most termites possible. Termite baiting systems also have an effect on the entire termite colony which suppresses their population and can eventually lead to death of the entire colony. Installing bait stations around your home provide excellent control when combined with a barrier/soil treatment. If you suspect infestation, contact a pest professional about subterranean termite treatment.
