Why Arizona Is a Termite Hotspot
Arizona's climate and soil conditions create ideal termite habitat. Here's why the risk is so high:
Termite Risk Level in Arizona
Arizona is classified as a "very heavy" termite zone. An estimated 1 in 5 Valley homes will experience termite activity.
Subterranean termites are the primary threat; drywood termites are a secondary concern in older homes. Mild winters and irrigated landscaping create ideal conditions.
Termite Prevention Tips for Arizona Homeowners
- Manage moisture near the foundation. Fix irrigation overspray and grade soil away to prevent pooling.
- Keep at least 6 inches between soil and any wood component of your home.
- Store firewood at least 20 feet from the structure, elevated off the ground.
- Periodically inspect foundation and garage walls for pencil-width mud tubes.
- Ensure proper ventilation and vapor barriers in crawl spaces.
- Get annual professional inspections -- especially important before buying or selling a home.
