Homeowners, landlords and anyone buying or selling a house in Peoria, 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 Peoria 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.
- 1Small kick-out holes in exposed wood.
- 2Mud in cracks of subfloor or joists.
- 3Crumbling baseboards behind furniture.
- 4Dry hexagonal pellets under window frames or eaves.
- 5Mud tubes running up foundation walls or piers.
- 6Piles of identical shed wings on windowsills.
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
Localized Wood, Foam, and Borate Treatment
$250–$1,500
A local treatment is cheaper than fumigation but only covers what the Peoria technician can find. Hidden drywood galleries elsewhere in the house are not touched.
- 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
Instead of a chemical barrier, baiting in Peoria removes the colony itself. Stations are checked on a schedule, commonly quarterly, and refilled.
- Time
- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
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 Peoria 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
Prices are typical published ranges. Ask what’s included before you compare quotes.
A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.How treatment works on a typical Peoria home.
In Peoria, 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 Peoria.
The termite you're most likely to meet in Peoria 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 Peoria'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 Peoria, 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 Peoria 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 Peoria out to Glendale and Surprise.

Watch porch lights at dusk.
What happens at an inspection.
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. 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.
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.
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. 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.
Mulch and termites.
Wood chips right against siding hold moisture termites like. A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation.
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
- Wells, drains, or water features limiting chemical use.
- Warranty type: retreatment only or damage repair.
- Attached garages, decks, and additions.
- Liquid barrier versus bait station system.
- Cubic footage under the tent for fumigation.
- Whole-house fumigation versus spot treatment.

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
Store-bought sprays usually kill only the termites you see. It also needs even coverage around the entire foundation. The product has to reach the whole colony. Treating an active colony is harder. Keep firewood away from the house. Fix leaks and clear gutters. Pull mulch back from the foundation. Some of the work is yours.
Termites in Peoria
A local provider who knows Peoria and Arizona can point out the specific conditions that matter most here before you commit to a plan. In Peoria, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. In Peoria, most of the housing is suburban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Peoria has a hot desert climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. A typical home in Peoria is worth around $415k, which puts a few hundred dollars for an inspection and prevention in perspective. With summer highs around 106°F, Peoria's hot desert climate decides when local termites are busiest. Most houses will see termites at some point. Termite activity in Arizona is above average. Peoria only sees about 9 inches of rain a year, so local termites gather wherever water collects, like sprinkler zones, hose bibs and AC drain lines.

Is termite treatment safe for kids and pets?
Ask for the label and follow any re-entry times. Bait stations are locked and buried. Soil treatments stay in the ground. Used according to the label, yes.
How do I know if I have termites or flying ants?
