Arizona homeowners face many pest challenges, but few are as destructive—and expensive—as termites. These silent invaders can cause significant damage before you even realize they’re there. With Arizona’s warm climate creating the perfect breeding ground, termite season is a serious concern.
In this guide, we’ll cover everything you need to know about termite season in Arizona—from spotting the early warning signs to taking action before it’s too late.
When Is Termite Season in Arizona?
Termites are active year-round in Arizona, but their peak swarming season occurs from March to late fall, with monsoon season (July–September) bringing an uptick in activity. The combination of moisture and warm temperatures creates the perfect environment for termites to expand their colonies.
Why Is Arizona a Hotspot for Termites?
Arizona’s dry climate might make it seem like termites wouldn’t be an issue, but these pests are highly adaptable. Several termite species thrive in the state, including:
- Subterranean Termites – The most destructive type, these termites build underground colonies and attack homes from below. According to the Environmental Protection Agency (EPA), subterranean termites are responsible for billions of dollars in damage annually.
- Drywood Termites – Unlike subterranean termites, these pests don’t need soil to survive. They infest dry, untreated wood, such as attic beams and furniture.
- Desert Dampwood Termites – Less common but still a threat, these termites prefer moist wood, often found in areas with leaky pipes or poor drainage.
How to Identify a Termite Infestation
Since termites work silently, it’s important to spot signs of an infestation before severe damage occurs. Look for:
1. Mud Tubes
Subterranean termites build mud tubes along walls, foundations, and crawl spaces to travel between their colony and their food source. These small, brown tunnels are a clear indicator of an infestation.
2. Hollow-Sounding Wood
Termites consume wood from the inside out, making surfaces sound hollow when tapped. If you notice this in your floors, walls, or furniture, termites could be inside.
3. Discarded Wings
During swarming season, termites shed their wings after finding a new nesting spot. Finding small, discarded wings near windowsills, doors, or lights is a sign that termites are nearby.
4. Frass (Termite Droppings)
Drywood termites leave behind tiny, pellet-like droppings (called frass) that resemble sawdust or coffee grounds. If you see small piles of this material, it’s time for an inspection.
5. Warped Doors and Windows
As termites tunnel through wood, they can cause structural warping, making doors and windows difficult to open or close. This is often mistaken for humidity issues, but termites could be the real culprit.

How to Prevent Termite Infestations
Prevention is key when it comes to termites. By taking proactive steps, you can reduce the risk of an infestation and protect your home from costly damage.
1. Eliminate Moisture Sources
Since termites thrive in humid environments, reducing moisture around your home is critical:
- Fix leaky pipes and faucets.
- Ensure proper drainage around the foundation.
- Keep gutters and downspouts clear to prevent water buildup.
2. Keep Wood Away from Your Home
Termites love untreated wood—so keep it far from your house:
- Store firewood at least 20 feet away from the home.
- Remove dead trees, stumps, and excess mulch.
- Use termite-resistant materials for decks and fencing.
3. Seal Entry Points
Termites can squeeze into the tiniest gaps. Regularly inspect and seal:
- Cracks in the foundation
- Gaps around windows and doors
- Utility line entry points
4. Schedule Regular Inspections
The best way to prevent termite damage is to catch infestations early. According to the National Pest Management Association, homeowners should schedule annual inspections to detect early signs of termite activity.
The Best Termite Treatment Options in Arizona
If termites have already invaded, don’t panic! There are effective treatment options to eliminate these destructive pests.
1. Liquid Termite Treatments
Professionals apply a liquid termiticide around the foundation to create a protective barrier. This method kills termites on contact and prevents new colonies from forming.
2. Bait Stations
Termite bait stations are placed around your home to attract and eliminate colonies before they reach your house. These eco-friendly traps are a long-term prevention strategy.
3. Fumigation (For Severe Infestations)
For widespread drywood termite infestations, fumigation may be required. This method involves sealing off the home and releasing a gas treatment to eliminate termites inside.
4. Wood Treatments
If termites have infested furniture or wooden structures, direct wood treatments using borate-based products can be applied to kill and prevent infestations.
