Unseen Threats: Subterranean Termites in the Phoenix Area During Fall

As the heat of summer gradually gives way to cooler temperatures, fall in the Phoenix area brings with it not only a welcome relief from scorching days but also the potential resurgence of a hidden menace – subterranean termites. While these destructive pests remain active year-round, their behavior during the fall months can be particularly concerning for homeowners. In this blog, we will delve into the world of subterranean termites in the Phoenix area during fall, highlighting the risks they pose and offering strategies for prevention.

Subterranean Termites: The Silent Destroyers

Subterranean termites are aptly named as they live underground and remain hidden from plain sight. These insects feed on wood and cellulose materials, making them a significant threat to homes and structures. Unlike drywood termites, subterranean termites require moisture to thrive, and the fall season in Phoenix provides them with the ideal conditions to seek out new food sources.

Fall: A Time of Increased Activity

Fall in the Phoenix area often brings more moderate temperatures and occasional rain, which creates the perfect environment for subterranean termites. During this season, these pests become more active and are more likely to venture out in search of food, including the wooden structures of your home.

Signs of Subterranean Termite Activity in Fall

Detecting subterranean termite infestations during the fall can be challenging since they remain hidden beneath the ground. However, there are signs to watch for, including:

  • Swarmers: Subterranean termites release winged reproductive termites (swarmers) during fall to establish new colonies. Seeing swarms of these insects around your property is a clear indication of a termite presence.
  • Mud Tubes: Termites construct mud tubes to maintain their moisture levels and protect themselves from predators. These tubes may appear on foundations, walls, or wooden structures.
  • Damaged Wood: Look for wood that sounds hollow when tapped or appears blistered, as this could indicate termite damage.

Preventing Subterranean Termite Infestations in Fall

Preventing subterranean termite infestations during the fall months is essential for protecting your property. Here are some prevention strategies to consider:

  • Regular Inspections: Schedule professional termite inspections to detect early signs of infestation.
  • Moisture Control: Reduce moisture around your home by fixing leaks, using proper drainage, and ensuring good ventilation in crawl spaces.
  • Wood-to-Soil Contact: Avoid direct wood-to-soil contact in and around your home by using concrete or metal barriers.
  • Termite-resistant Materials: Use termite-resistant building materials where possible.
  • Chemical Barriers: Consider applying liquid termiticides or installing bait systems to deter termite activity.
  • Landscaping: Keep plants and mulch away from the foundation to prevent termites from gaining easy access to your home.


Subterranean termites are a year-round threat in the Phoenix area, but their activity becomes more pronounced during the fall months when conditions are favorable for their foraging and swarming behaviors. To protect your home from the silent destruction of these pests, it’s essential to remain vigilant, schedule regular termite inspections with a company such as Arizona Wild, and implement preventive measures. By staying proactive, you can ensure that your property remains termite-free and secure during the beautiful autumn season in Phoenix.
