Homeowners, landlords and anyone buying or selling a house in Glendale, 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 Glendale 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.

- 3Termite tubes hanging down from ceilings or joists.
- 4Discarded wings caught in spider webs.
- 5Doors and windows that suddenly stick.
- 6Live pale insects inside a broken mud tube.
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)
The label on the termiticide is federal law, so a licensed Glendale applicator follows it exactly. Ask which active ingredient is used and how long it lasts.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation
Fumigation for Drywood Termites
$1,200–$4,000 (often $1–$4 per square foot)
Tenting is thorough but leaves no residual protection behind. New drywood swarmers can land on a Glendale home the following season, so follow-up inspections still matter.
- Time
- 2–3 days including tenting and aeration
- Best for
- Widespread drywood termites throughout a structure
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year
Each station holds cellulose bait laced with a chitin synthesis inhibitor. Workers around a Glendale home share it, cannot molt, and the colony dies over weeks to months.
- 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.
Check under the kitchen sink for dampness and soft cabinet wood. Plumbing walls are a common path for termites coming up from a slab.How treatment works on a typical Glendale home.
In Glendale, 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. 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.
Which termites live around Glendale.
The termite you're most likely to meet in Glendale 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 Glendale's dry heat, desert subterranean termites can build tubes that hang free from ceilings. They'll eat fences, door frames, anything wooden.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
Swarm season is when termites show themselves. In Glendale, 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.
Where to look around your house.
Many homes in Glendale 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. Outside, watch for mud tubes behind shrubs. Keep soil and mulch below the slab edge. The same advice applies across the area, from Glendale out to Peoria and Phoenix.

- Summer: swarm season in Glendale, usually after monsoon storms. Watch porch lights at dusk. - Summer: with highs around 106°F in Glendale, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 9 inches of rain a year in Glendale, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Glendale, before swarm season starts.
What happens at an inspection.
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. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help.
Termites or ants?
- Wings: termite wings are all the same length. Ant wings aren’t. - 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.
Getting ready for treatment day.
Soil treatments and bait stations need little prep. Clear a path along the outside walls. Move stored boxes away from garage walls. 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.
Mulch and termites.
Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- Which termites did you find, and where? - 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?
What affects the price
- Cubic footage under the tent for fumigation.
- Whole-house fumigation versus spot treatment.
- Warranty type: retreatment only or damage repair.
- Extent of existing damage needing repair.
- Access to crawl spaces and attics.
- Linear feet of foundation to be treated.

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
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.

Simple ways to keep termites away
- Caulk gaps around plumbing and utility penetrations.
- Trim shrubs so foundation walls stay visible and dry.
- Install a vapor barrier over crawl space soil.
- Extend downspouts so water drains away from walls.
- Keep six inches between soil and siding or wood.
- Use borate-treated or pressure-treated lumber for repairs.

Questions people ask
What is the difference between subterranean and drywood termites?
Subterranean termites live in soil and build mud tubes. Drywood termites live inside the wood and leave tiny pellets. Around Glendale, the subterranean kind causes most problems.
Are mud tubes always a sign of active termites?
Not always. Old tubes can stay on a wall for years. Break off a piece and check back in a week. If it's rebuilt, they're active.
How do I know if I have termites or flying ants?
Check the wings and the waist. Termite wings are all the same length. Ants have a pinched waist; termites don't. Save one in a bag for the inspector.
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.
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.
When is termite swarming season?
In Glendale, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Glendale, 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 Glendale, the usual culprit is the desert subterranean termite.
