If you relocated here from the East Coast or California, you've probably heard horror stories about termites — and you might assume buying a home in the Phoenix metro means signing up for a constant battle with destructive bugs. The reality in our desert is different.

Yes, we have termites. But the risk, behavior, and impact here are not the same as in wetter parts of the country. Let me walk you through what you actually need to know — whether you're buying, selling, or just trying to be a smart homeowner.

Meet the local culprit: desert subterranean termites

In the Phoenix metro, the primary problem species is the desert subterranean termite — a type of subterranean termite adapted to arid climates. These termites live in colonies underground and travel through small mud tubes to reach wood or cellulose above ground.

A few things to know about them: they prefer moist soil pockets and tend to appear where irrigation or water is present — think landscaping, foundations with poor drainage, or areas around leaky pipes. They typically attack the softer interior wood, leaving a "honeycomb" pattern inside while the exterior still looks fine. And their activity is generally slower and more localized than what you'd see in high-moisture environments along the coast or Southeast.

One important note: we do not commonly deal with Formosan termites here — the highly aggressive, fast-moving species that causes serious structural damage in Gulf Coast states. That's a key distinction.

How our termites compare to other regions

Region	Main termites	Behavior
Phoenix metro	Desert subterranean	Soil-based; travel through mud tubes to reach wood
Coastal California	Subterranean & drywood	Soil and directly in dry wood (attics, framing)
East Coast / Southeast	Subterranean (incl. Formosan in some areas)	Highly aggressive, moisture-loving; large fast-moving colonies

Drywood termites — more common in coastal California and some southeastern states — can infest dry wood directly, like rafters, furniture, and trim, without needing soil contact at all. In those markets, whole-house fumigation is more common and infestations can be much harder to catch early.

Our desert subterranean termites, by contrast, need soil moisture and shelter to thrive, and they often reveal themselves with visible mud tubes on foundations, stem walls, or interior walls. That visibility actually works in our favor.

Why this isn't the crisis it might be elsewhere

Even though termites are present valley-wide, several desert factors keep them from being the structural threat they are in wetter climates:

Low year-round moisture. Termites thrive in warm, humid conditions. Our heat is ideal for them, but the persistent dryness limits how large and aggressive colonies can get — unless there's a man-made water source like a leaky irrigation system or poor drainage near the foundation.

Fewer high-destruction species. The most aggressive subterranean termites are concentrated in warm, humid coastal and Gulf states where they can build massive colonies and damage structures quickly. That's simply not our environment.

Slab foundations work in our favor. Most Phoenix-area homes are built on concrete slabs, which creates a defined perimeter where treatment and monitoring are highly effective. On the East Coast, the mix of basements, crawl spaces, older wood framing close to soil, and higher moisture creates more entry points and hiding places.

Inspections are standard practice here. Termite inspections are routine in Arizona real estate transactions, and localized soil treatments along foundations are common and effective when done by a licensed professional. Catching problems early — before they become structural — is exactly what the system is designed to do.

Practical tips for Phoenix homeowners

• 1Keep soil and landscaping a few inches below the top of your foundation to eliminate hidden access points.
• 2Don't stack firewood or lumber directly against the house — especially right on the soil.
• 3Fix irrigation leaks, condensation issues, and drainage problems. Moisture near the foundation is an open invitation.
• 4Schedule regular termite inspections, and consider a professional treatment or warranty plan — especially for older homes or heavily irrigated lots.

Think of it like any other desert-specific maintenance item: A/C servicing, roof inspections, irrigation checks. Important to stay on top of — and absolutely manageable when you do.

If you have questions about a home you're buying or selling and want to know what to expect from the inspection process, I'm always happy to walk you through it.
