The short version
Most termite problems in Scottsdale are desert subterranean termites, and the usual fix is a liquid soil treatment or bait stations, placed where the soil stays damp. Drywood termites need fumigation or wood treatment instead. Start with an inspection; $75–$250 is typical.
- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up from July through September.

- Insurance usually doesn’t cover termite damage.
Homeowners, landlords and anyone buying or selling a house in Scottsdale, 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 Scottsdale stay mild, with average lows near 43°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.
- 1Crumbling baseboards behind furniture.
- 2Mud in cracks of subfloor or joists.
- 3Screwdriver sinks easily into sills or trim.
- 4Wood that sounds hollow when tapped.
- 5Discarded wings caught in spider webs.
- 6Dry hexagonal pellets under window frames or eaves.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.
📅
Termite activity through the year in Scottsdale
Spring
swarm season in Scottsdale, usually after monsoon storms. Watch porch lights at dusk.
Summer
with highs around 105°F in Scottsdale, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
Fall

Winter
a good time to book an inspection in Scottsdale, before swarm season starts.
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
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 Scottsdale 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
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Spot treatment works when the Scottsdale 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
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Baiting is slower than a liquid barrier but reaches deeper colonies. For a Scottsdale home on a well or with a finished slab, it is often the cleaner option.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Prices are typical published ranges. Ask what’s included before you compare quotes.
Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.How treatment works on a typical Scottsdale home.
Bait stations are the other main option. They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. For Scottsdale homes, on a slab, the crew treats the soil along the outside walls. Under patios and garage floors, they drill small holes. Treatment goes in through the holes, which get patched afterward.
Which termites live around Scottsdale.
Drywood termites turn up now and then, mostly in older wood. Look for tiny piles of hard, sand-like pellets. In Scottsdale'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 Scottsdale is the desert subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.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 Scottsdale 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 Scottsdale out to Tempe and Mesa. Many homes in Scottsdale 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 Scottsdale.
- Summer: with highs around 105°F in Scottsdale, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 10 inches of rain a year in Scottsdale, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Scottsdale, before swarm season starts. - Summer: swarm season in Scottsdale, usually after monsoon storms. Watch porch lights at dusk.
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
- Extent of existing damage needing repair.
- Linear feet of foundation to be treated.
- Wells, drains, or water features limiting chemical use.
- Warranty type: retreatment only or damage repair.
- Cubic footage under the tent for fumigation.
- Liquid barrier versus bait station system.

What's your biggest concern about termites?
When to call for help
Termites leave mud. Carpenter ants leave clean tunnels and sawdust. It's also the cheapest termite service. Lenders often ask for one. Get a wood-destroying insect (WDI) report either way. Buying or selling? Hollow-sounding wood is another clue. Call if you see mud tubes, pellets or an indoor swarm.
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 Scottsdale
Scottsdale only sees about 10 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 105°F, Scottsdale's hot desert climate decides when local termites are busiest. A typical home in Scottsdale is worth around $780k, which puts a few hundred dollars for an inspection and prevention in perspective.

Simple ways to keep termites away
- Address wood-to-soil contact at steps, fences, and trellises.
- Ventilate crawl spaces and control humidity.
- Install a vapor barrier over crawl space soil.
- Keep gutters clean so water does not pool.
- Grade soil to slope away from the foundation.
A damp cabinet under a leaky sink is worth reporting to your landlord early. Fixing the leak removes what draws termites in.Did you know?

Questions people ask
What does a WDI report include?
It lists any termites or damage found. It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach.
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.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Most homes around Scottsdale sit on slabs, so inspectors check those spots first.
Do I need a termite inspection when buying a house?
Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report. Either way, it's cheap peace of mind. Ask your agent when it's due.
When is termite swarming season?
For Scottsdale homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Scottsdale 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 termite baits or liquid treatments more common?
Most professionals use both. A homeowner comparing quotes should expect to see both baits and a liquid barrier proposed: 48% of professionals in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) primarily used the two together.
Are termites common in Arizona?
Around Scottsdale, the usual culprit is the desert subterranean termite.
