- Look for mud tubes, shed wings and hollow-sounding wood.
- Swarms usually show up from July through September.

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.

- 2Doors and windows that suddenly stick.
- 3Tiny pinholes in drywall rimmed with mud.
- 4Small kick-out holes in exposed wood.
- 5Live pale insects inside a broken mud tube.
- 6Layered, honeycombed wood packed with soil.
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.

- 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 Gilbert home the following season, so follow-up inspections still matter.

- Best for
- Widespread drywood termites throughout a structure
Localized Wood, Foam, and Borate Treatment
$250–$1,500
Foam termiticide is injected into wall voids liquid cannot reach. In Gilbert this pairs well with a soil barrier around tricky slab construction.

A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.Which termites live around Gilbert.
In Gilbert'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 Gilbert 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.
Local termites conditions in Gilbert.
Knowing Gilbert'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 Gilbert 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. Gilbert 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. In Gilbert, the area is mostly suburban, 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 Gilbert usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first.
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.
Swarm season is when termites show themselves. In Gilbert, 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 Gilbert 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 Gilbert out to Chandler and Mesa.
A year of termites in Gilbert.
- Summer: with highs around 106°F in Gilbert, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 9 inches of rain a year in Gilbert, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Gilbert, before swarm season starts. - Summer: swarm season in Gilbert, usually after monsoon storms. Watch porch lights at dusk.
What happens at an inspection.
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. 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.
Termites or ants?
- 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. - Waist: termites are thick through the middle. Ants are pinched.
Getting ready for treatment day.
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. Soil treatments and bait stations need little prep.
Mulch and termites.
Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes.
Questions to ask before you sign.
- 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 product or system will you use?
What affects the price
- Warranty type: retreatment only or damage repair.
- Wells, drains, or water features limiting chemical use.
- Time of year and how booked up local companies are.
- Attached garages, decks, and additions.
- Local labor rates and licensing requirements.
- Species: subterranean, drywood, or Formosan.

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
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
- Keep mulch at least a foot from the foundation.
- Address wood-to-soil contact at steps, fences, and trellises.
- Trim shrubs so foundation walls stay visible and dry.
- Screen attic and foundation vents with fine mesh.
- Inspect used furniture for drywood pellets before bringing indoors.
- Extend downspouts so water drains away from walls.

Questions people ask
Can termites damage a house on a concrete slab?
They come up through expansion joints, plumbing gaps and small cracks. Most homes around Gilbert sit on slabs, so inspectors check those spots first. Yes.
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.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
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 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.
What is a termite renewal contract?
In Gilbert, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In 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.
