As we head into 2026, Arizona homeowners are already seeing increased termite activity—especially in the West Valley. Recent late-season rainfall has created ideal moisture conditions for subterranean termites, making this the perfect time to strengthen your home’s termite protection.
If you’re a homeowner looking for reliable termite control or long-lasting termite treatment in Surprise, AZ, this updated 2026 guide explains what to look for, how to stay protected, and why Termidor® HE continues to outperform other solutions for Arizona’s desert environment.
What Makes Subterranean Termites a Major Risk in Arizona?
Subterranean termites are the most destructive termite species in Arizona. They nest deep underground and build protected mud tubes to reach your home’s wooden structure. Once active, a colony can cause significant structural damage long before visible signs appear.
Key characteristics include:
- Colonies ranging from 50,000 to over 500,000 termites
- Mud tubes used to safely travel from soil to wood
- Queens capable of laying hundreds of eggs per day
- Strong attraction to moisture—especially after rain, irrigation, and leaks
Because they operate silently behind walls, slabs, and foundations, early detection typically requires a professional inspection.
Why Recent Rainfall Has Increased Termite Activity
The West Valley—including Surprise, El Mirage, Peoria, and Sun City—received notable rainfall over the past few weeks. Moisture softens the soil and triggers foraging, making termites more active and more likely to enter homes.
If you’ve recently noticed mud tubes, discarded wings, or bubbling paint, this weather is likely the reason. Increased moisture is one of the strongest predictors of winter and early-spring termite activity.
Arizona’s Termite Swarming Season in 2026
Arizona typically experiences two major swarming seasons:
- Spring Swarm: March – May
- Monsoon Swarm: July – September
Because winter storms left behind elevated moisture levels, homeowners in 2026 may see swarmers earlier and in larger numbers. Finding wings on windowsills or floors is a clear sign to schedule a professional termite inspection.
Common Signs You Need a Termite Treatment
Termites often remain hidden until damage becomes severe. Call a professional immediately if you notice:
- Pencil-thin mud tubes along exterior walls, slabs, or the stem wall
- Wood that sounds hollow when tapped
- Walls with bubbling, blistering, or peeling paint
- Discarded wings near entry points such as doors or windows
- Small piles of “coffee-ground-like” droppings (frass)
These signs indicate active tunneling, feeding, or recent swarming—and require immediate termite treatment to prevent spreading.

You can lower your risk of future infestations by following these prevention strategies:
- Repair irrigation leaks, A/C condensation lines, and plumbing issues quickly
- Ensure soil and mulch are kept below stucco and wood contact points
- Improve drainage so water flows away from your home’s foundation

Moisture control is especially important in early 2026 due to the recent rain spikes across the West Valley.
