The short version
Most termite problems in Tempe 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.
- Drywood termites need wood treatment or fumigation instead.
- An inspection typically costs $75–$250.
- Insurance usually doesn’t cover termite damage.
Anyone in Tempe who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winters around Tempe 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.
- 1Tiny pinholes in drywall rimmed with mud.
- 2Winged swarmers indoors, especially in spring.
- 3Mud in cracks of subfloor or joists.
- 4Blistered or bubbling paint on wood surfaces.
- 5Sagging or spongy floors near exterior walls.
- 6Damage found during a remodel or repair.
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.
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 Tempe 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 Tempe 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
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 Tempe 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

In a basement, the wooden sill plate on top of the block wall is the first piece of wood termites reach.Which termites live around Tempe.
Drywood termites turn up now and then, mostly in older wood. Look for tiny piles of hard, sand-like pellets. In Tempe'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 Tempe is the desert subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
Local termites conditions in Tempe.
An inspection in Tempe usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Tempe'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 Tempe 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. Tempe 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 Tempe 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.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.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 Tempe 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 Tempe out to Scottsdale and Mesa. Many homes in Tempe 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 Tempe.
- Fall: with about 9 inches of rain a year in Tempe, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 106°F in Tempe, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Summer: swarm season in Tempe, usually after monsoon storms. Watch porch lights at dusk. - Winter: a good time to book an inspection in Tempe, before swarm season starts.
What happens at an inspection.
Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two. Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. 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.
Mark sprinkler heads and any buried lines. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep. Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation. Wood chips right against siding hold moisture termites like.
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
- Liquid barrier versus bait station system.
- Attached garages, decks, and additions.
- Amount of drilling through concrete and patios.
- Wells, drains, or water features limiting chemical use.
- Warranty type: retreatment only or damage repair.
- Slab, crawl space, or basement construction.

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
- Ventilate crawl spaces and control humidity.
- Trim shrubs so foundation walls stay visible and dry.
- Paint or seal exposed exterior wood.
- Inspect used furniture for drywood pellets before bringing indoors.
- Install a vapor barrier over crawl space soil.
- Check the foundation for mud tubes every spring.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
For Tempe homes, soldier termites can't feed themselves, so the workers feed them mouth to mouth.
Questions people ask
How do I choose a termite company?
Compare the proposals, not just the totals. Ask what the warranty covers. Ask which termites they found and what product they'll use. Make sure they're licensed in Arizona.
How do I know if I have termites or flying ants?
Save one in a bag for the inspector. Ants have a pinched waist; termites don't. Termite wings are all the same length. Check the wings and the waist.
What is the difference between subterranean and drywood termites?
Around Tempe, the subterranean kind causes most problems. Drywood termites live inside the wood and leave tiny pellets. Subterranean termites live in soil and build mud tubes.
Are mud tubes always a sign of active termites?
If it's rebuilt, they're active. Break off a piece and check back in a week. Old tubes can stay on a wall for years. Not always.
Do I need a termite inspection when buying a house?
Ask your agent when it's due. Either way, it's cheap peace of mind. Many lenders ask for a wood-destroying insect (WDI) report. Usually, yes.
When is termite swarming season?
For Tempe homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Tempe 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 Tempe, the usual culprit is the desert subterranean termite.
