Anyone in Gilbert who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
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. Average winter lows near 41°F slow termites near the surface around Gilbert, but they move deeper and keep feeding under heated homes.

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
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 Gilbert 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 Gilbert 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
Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A liquid barrier treatment around a Gilbert home means trenching and rodding termiticide into the soil along the foundation. Non-repellent products let termites pass through and carry the chemical home to the colony under Gilbert.
- Time
- Half a day to a full day
- Best for
- Active subterranean termites; fast knockdown around the foundation

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 Gilbert home.
They're spaced every 10 to 20 feet. Bait stations are the other main option. Treatment goes in through the holes, which get patched afterward. Under patios and garage floors, they drill small holes. Around Gilbert, on a slab, the crew treats the soil along the outside walls. The stations are checked on a schedule, often every few months. Termites carry the bait back to the colony.
Which termites live around Gilbert.
Look for tiny piles of hard, sand-like pellets. Drywood termites turn up now and then, mostly in older wood. It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Gilbert is the desert subterranean termite. They'll eat fences, door frames, anything wooden. In Gilbert's dry heat, desert subterranean termites can build tubes that hang free from ceilings.
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.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Drywood termites swarm on spring and summer evenings, often near lights. Around Gilbert, desert subterranean termites usually swarm from July through September, around dusk after monsoon storms. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from Gilbert out to Chandler and Mesa. Keep soil and mulch below the slab edge. Outside, watch for mud tubes behind shrubs. Look where pipes come through the floor. Check the garage edges and behind baseboards. Many homes in Gilbert sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Gilbert.
- Summer: swarm season in Gilbert, usually after monsoon storms. Watch porch lights at dusk. - Winter: a good time to book an inspection in Gilbert, before swarm season starts. - Fall: with about 9 inches of rain a year in Gilbert, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 106°F in Gilbert, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
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. - Wings: termite wings are all the same length. Ant wings aren’t. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations. Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the Gilbert 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. Flag sprinkler heads and buried lines.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Gilbert's dry climate the risk is irrigation and leaky hose bibs rather than rain. Pull mulch back from the foundation and keep the layer thin. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What product or system will you use? - Which termites did you find, and where? - What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot?
What affects the price
- Wells, drains, or water features limiting chemical use.
- Time of year and how booked up local companies are.
- Extent of existing damage needing repair.
- Amount of drilling through concrete and patios.
- Annual renewal and monitoring fees.
- Cubic footage under the tent for fumigation.

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
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.

Questions people ask
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
Can I treat termites myself?
The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see. Prevention, yes. An active colony is harder.
How do I know if I have termites or flying ants?
Ants have a pinched waist; termites don't. Save one in a bag for the inspector. Check the wings and the waist. Termite wings are all the same length.
When is termite swarming season?
Around Gilbert, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Gilbert, 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 Gilbert, the usual culprit is the desert subterranean termite.
