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
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. 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.

- 2Buckling laminate or warped hardwood flooring.
- 3Screwdriver sinks easily into sills or trim.
- 4Sagging or spongy floors near exterior walls.
- 5Live pale insects inside a broken mud tube.
- 6Mud in cracks of subfloor or joists.
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.

A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.Which termites live around Scottsdale.
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. 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.
Local termites conditions in Scottsdale.
A provider who works Scottsdale 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. Scottsdale 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. Across Scottsdale, 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. An inspection in Scottsdale usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Scottsdale'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 downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.When termites swarm here.
Across Scottsdale, 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. 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.
Where to look around your house.
Check the garage edges and behind baseboards. Look where pipes come through the floor. 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.
A year of termites in Scottsdale.
- Summer: 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: 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.
What happens at an inspection.
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. On a slab, they focus on joints, cracks and pipe gaps.
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.
Keep kids and pets inside while the Scottsdale crew applies the product, and ask how long to stay off treated soil. In Arizona, heterotermes aureus flies in late afternoon or early evening in July, August and September (UC IPM), the summer monsoon months; drywood swarmers fly in daytime in summer and fall. Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Scottsdale's dry climate the risk is irrigation and leaky hose bibs rather than rain. Wood chips touching the siding trap the moisture termites are after.
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
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Local labor rates and licensing requirements.
- Whole-house fumigation versus spot treatment.
- Time of year and how booked up local companies are.
- Extent of existing damage needing repair.

What's your biggest concern about termites?
When to call for help
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. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
What you can do yourself
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. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.

Simple ways to keep termites away
- Repair rotting trim, fascia, and window frames.
- Address wood-to-soil contact at steps, fences, and trellises.
- Set deck and porch posts on concrete, not soil.
- Keep six inches between soil and siding or wood.
- Grade soil to slope away from the foundation.
- Use borate-treated or pressure-treated lumber for repairs.
A liquid soil treatment goes into a trench along the foundation so termites cross it on their way to the house.Did you know?
Across Scottsdale, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
Across Scottsdale, when danger shows up, soldier termites bang their heads against the tunnel walls to warn the colony.
Questions people ask
How long do termite bait stations take to work?
Termites have to find the stations first. Then the bait spreads through the colony. Usually several weeks to a few months.
Are mud tubes always a sign of active termites?
Break off a piece and check back in a week. If it's rebuilt, they're active. Not always. Old tubes can stay on a wall for years.
What does a WDI report include?
It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach. It lists any termites or damage found.
How do I choose a termite company?
Ask what the warranty covers. Compare the proposals, not just the totals. Make sure they're licensed in Arizona. Ask which termites they found and what product they'll use.
Do I need a termite inspection when buying a house?
Either way, it's cheap peace of mind. Ask your agent when it's due. Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report.
Are termite treatment prices going up?
Across Scottsdale, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Scottsdale, 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 Scottsdale, the usual culprit is the desert subterranean termite.
