Subterranean termites are a significant concern for southern Arizona homeowners—including Tucson and Green Valley. These pests can cause extensive damage to homes if not identified and treated promptly. Understanding what subterranean termites are, the infestation signs to look for, and how to treat them can help protect your property and potentially save you thousands of dollars in damages.

What Are Subterranean Termites?

Subterranean termites are a species of termite that live in underground colonies where there is plenty of moisture for them to survive. The increased moisture from the summer monsoons combined with the regular warm weather make the late summer and early fall months ideal conditions for termite activity.

Unlike other termite species, subterranean termites don’t nest in wood and other cellulose they consume. Instead, workers build intricate tunnel systems to access food sources and bring it back to the rest of the colony. Due to their destructive eating habits, they can cause severe structural damage to homes as they feed on wood from the inside out, often going undetected until significant harm is done.

Signs of Subterranean Termite Infestation

Early detection is crucial in preventing substantial damage. Homeowners should be vigilant and look for the following signs of subterranean termite activity:

• Mud Tubes: Subterranean termites construct mud tubes to travel between their underground colonies and food sources. These tubes protect them from predators and maintain the necessary moisture levels. Look for these pencil-thin, mud-like structures on foundations, walls, and other surfaces.
• Exit Holes: On interior walls, subterranean termites will make exit holes. These holes are small—about the size of a pin or small nail—and often have a small amount of dirt around the opening.
• Wood Damage: Termites consume wood from the inside out, leaving a thin veneer on the surface. Tap on wooden structures; if you hear a hollow sound, it may indicate termite damage. Additionally, look for blistering or dark spots on wood surfaces.

Treatment Options for Subterranean Termites

Once an infestation is confirmed, it is essential to act quickly. Due to the destructive nature of subterranean termites, it’s always recommended that a professional pest control company is contacted to perform an effective treatment from the start.

• Liquid Termiticides: Professional pest control companies can apply liquid termiticides to the soil around the foundation of your home. This treatment forms a protective barrier that eliminates the worker termites that cross through the barrier in search of food and back to the nest.
• Baiting Systems: The use of an advanced baiting system like the Sentricon® System with Always Active™ technology is an effective, long-term approach to termite control. The stations form a protective ring around the structure, targeting the termites based on their natural foraging behavior. As an added benefit, the bait doesn’t break down in the harsh desert climate like the liquid termiticide does, making it a great ongoing control measure.

Preventing Future Infestations

Prevention is key to protecting your home from future termite infestations.

• Reduce Moisture: Subterranean termites need moisture to survive. Fix any leaks, ensure proper drainage around your home, and use dehumidifiers in damp areas.
• Remove Wood Debris: Keep your yard free of wood debris, such as logs, branches, and old tree stumps. Store firewood away from your home and off the ground.
• Regular Inspections: Schedule regular termite inspections with a professional pest control company. Early detection can save you from costly repairs.
