Homeowners, landlords and anyone buying or selling a house in Phoenix, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winters around Phoenix stay mild, with average lows near 45°F, so colonies keep feeding all year. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.

Treatment options and typical costs
Termite Inspection and WDI Report
$75–$250
The inspector checks the foundation, garage, attic and damp spots. Bring up anything you’ve noticed.
- Time
- 60–120 minutes
- Best for
- Every job, real estate closings, and yearly peace of mind
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Spot treatment works when the Phoenix inspector can see and reach the whole infestation. Small drywood galleries, porch posts, and exposed sills are typical targets.
- Time
- 1–3 hours
- Best for
- Small drywood spots, wall voids, and exposed framing
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A soil barrier stops termites from reaching wood through the ground. For most Phoenix homes with active subterranean termites, this is the fastest way to end feeding.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Annual Renewal and Monitoring
$150–$400 per year
Some Phoenix homeowners drop the renewal after a quiet year or two. That usually voids the warranty and leaves the barrier untested.
- Time
- 30–60 minutes per visit
- Best for
- Keeping a treated home protected after the initial job

On the slab homes common around Phoenix, drilling through patios, porches and garage floors adds labor.
Local termites conditions in Phoenix.
An inspection in Phoenix usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Phoenix's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Phoenix and Arizona every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Phoenix sits in a hot desert climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. For Phoenix homes, the area is mostly urban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Which termites live around Phoenix.
Drywood termites turn up now and then, mostly in older wood. Look for tiny piles of hard, sand-like pellets. In Phoenix's dry heat, desert subterranean termites can build tubes that hang free from ceilings. They'll eat fences, door frames, anything wooden. The termite you're most likely to meet in Phoenix is the desert subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
When termites swarm here.
A swarm outside means a colony is nearby. A swarm inside usually means it's in the house. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. For Phoenix homes, desert subterranean termites usually swarm from July through September, around dusk after monsoon storms. Drywood termites swarm on spring and summer evenings, often near lights.
Where to look around your house.
Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge. The same advice applies across the area, from Phoenix out to Tempe and Glendale. Many homes in Phoenix sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks. Check the garage edges and behind baseboards. Look where pipes come through the floor.
A year of termites in Phoenix.
- Summer: with highs around 106°F in Phoenix, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 8 inches of rain a year in Phoenix, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Phoenix, before swarm season starts. - Summer: swarm season in Phoenix, usually after monsoon storms. Watch porch lights at dusk.
Ways to keep the cost down.
- Fix leaks and drainage first. Moisture brings termites back. - Ask about both bait and liquid options for your house. - If you already have a warranty, keep the renewal current. - Book before swarm season, when schedules fill up. - Get two or three quotes, and compare what each one covers.
What happens at an inspection.
On a slab, they focus on joints, cracks and pipe gaps. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. Most inspections take an hour or two. The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Mark sprinkler heads and any buried lines. Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched. Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
Questions to ask before you sign.
- What product or system will you use? - Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost? - What do I need to do before and after treatment? - Which termites did you find, and where?
What affects the price
- Local labor rates and licensing requirements.
- Amount of drilling through concrete and patios.
- Annual renewal and monitoring fees.
- Liquid barrier versus bait station system.
- Warranty type: retreatment only or damage repair.
- Access to crawl spaces and attics.
- Number of bait stations required.
- Linear feet of foundation to be treated.

What's your biggest concern about termite control costs?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way.
What you can do yourself
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see.
Termites in Phoenix
Phoenix only sees about 8 inches of rain a year, so local termites gather wherever water collects, like sprinkler zones, hose bibs and AC drain lines. Termite activity in Arizona is above average. Most houses will see termites at some point. With summer highs around 106°F, Phoenix's hot desert climate decides when local termites are busiest. A typical home in Phoenix is worth around $418k, which puts a few hundred dollars for an inspection and prevention in perspective.

Simple ways to keep termites away
- Fix leaking hose bibs, faucets, and pipes promptly.
- Store firewood well away from the house, off the ground.
- Keep mulch at least a foot from the foundation.
- Trim shrubs so foundation walls stay visible and dry.
- Screen attic and foundation vents with fine mesh.
- Address wood-to-soil contact at steps, fences, and trellises.
Keep the inspection diagram, treatment record and warranty together. Buyers and inspectors will ask for them later.Did you know?
For Phoenix homes, termites have been chewing wood for well over 100 million years, since the age of the dinosaurs.
Questions people ask
How much does a termite inspection cost?
Usually $75–$250. Some companies credit it toward treatment if you go ahead. It's worth asking.
How much does annual termite renewal cost?
Usually $150–$400 a year. It keeps the warranty active and includes a yearly check. Letting it lapse usually ends the warranty.
How much does termite fumigation cost?
Usually $1,200–$4,000, often $1–$4 per square foot. It's mainly for drywood termites. Most homes around Phoenix never need it.
Why do termite quotes vary so much?
Companies measure differently and use different products. Some include a warranty or yearly checks. Drilling through concrete adds labor. Compare what's included, line by line.
Is termite treatment safe for kids and pets?
Used according to the label, yes. Soil treatments stay in the ground. Bait stations are locked and buried. Ask for the label and follow any re-entry times.
How long does termite treatment take?
A liquid barrier takes half a day to a day. Bait stations take a few hours to install. Fumigation takes two to three days.
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
When is termite swarming season?
For Phoenix homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Phoenix homes, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in Arizona?
Around Phoenix, the usual culprit is the desert subterranean termite.
