What to look for
Termites work quietly. A colony can feed inside a wall for years. Winters around Avondale stay mild, with average lows near 42°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.

Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)
A liquid barrier treatment around an Avondale 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 Avondale.

Cardboard boxes stacked on a garage slab are termite food sitting right on their doorstep. Keep storage on shelves.How treatment works on a typical Avondale home.
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. For Avondale homes, 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.
Which termites live around Avondale.
Drywood termites turn up now and then, mostly in older wood. Look for tiny piles of hard, sand-like pellets. In Avondale'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 Avondale is the desert subterranean termite. It nests in soil and builds mud tubes to reach wood. It needs steady moisture.
Sealing the gap where pipes enter the house takes away one of the easiest routes in. It won't replace treatment, but it helps.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 Avondale 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 Avondale out to Goodyear and Peoria. Many homes in Avondale 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.

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?
- 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. 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. Clear a path along the outside walls. Move stored boxes away from garage walls.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
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
- Attached garages, decks, and additions.
- Local labor rates and licensing requirements.
- Linear feet of foundation to be treated.
- Number of bait stations required.
- Slab, crawl space, or basement construction.
- 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
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.

Is termite treatment safe for kids and pets?
Used according to the label, yes. Soil treatments stay in the ground. Bait stations are locked and buried. Ask for the label and follow any re-entry times.
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
Will termites come back after treatment?
They can. Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for.
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 Avondale, the subterranean kind causes most problems.
How much does termite treatment cost?
For Avondale homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along.
