Understanding Subterranean Termites in San Jose

Behavior and Infestation Patterns

San Jose is home to western subterranean termites. Subterranean termites nest in the soil and construct mud tunnels using soil, saliva, and excrement, to serve as protected passageways for their foraging activities. They thrive in moist environments and gain access to homes through cracks and gaps in foundations. Of the several species of termites that are endemic to the Santa Clara Valley, subterraneans are the most voracious.

Signs of Infestation

Early detection is crucial to minimize damage. Look for swarmers (winged termites) in the spring and fall on the first sunny day after a rain, mud tubes along walls, and damaged or unstable wood.

Prevention

While there’s no way to absolutely prevent an infestation, there are some ways to make your home less attractive. Focus on moisture control, eliminating earth to wood contact, removing scrap wood and other cellulose debris from under and around your home, and scheduling regular inspections by licensed pest control professionals.

Treatment

Subterranean termites cannot be eradicated through fumigation. Most homeowners are familiar with fumigation which is the treatment of drywood termites but will deprioritize treatment of subterranean termites and are surprised when they’re told they remain after contracting a fumigation. Due to the nesting habits of subterranean termites, eradication requires applying a barrier of termiticide around the perimeter of the structure and occasionally any other areas where the foundation meets the soil.

Conclusion

By understanding their behavior, recognizing signs of infestation, and implementing preventive measures, homeowners can protect their properties.
