Anyone in Glendale who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
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 46°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.

- 3Wood that sounds hollow when tapped.
- 4Winged swarmers indoors, especially in spring.
- 5Blistered or bubbling paint on wood surfaces.
- 6Doors and windows that suddenly stick.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.

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.

- 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)
This is the workhorse treatment for subterranean termites in Glendale. Applicators trench, drill through slabs where needed, and saturate the soil.

- Active subterranean termites; fast knockdown around the foundation
Bait Station System with Monitoring
$1,500–$3,500 install, plus $300–$500 per year

- 2–4 hours to install; checked quarterly
- Best for
- Colony elimination, wells and slabs, homes near water
Annual Renewal and Monitoring
$150–$400 per year
Some Glendale homeowners drop the renewal after a quiet year or two. That usually voids the warranty and leaves the barrier untested.

Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.How treatment works on a typical Glendale home.
The stations are checked on a schedule, often every few months. Termites carry the bait back to the colony. 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 Glendale, on a slab, the crew treats the soil along the outside walls.
Which termites live around Glendale.
Look for tiny piles of pellets that look like coarse sand. Drywood termites are common around Glendale as well, flying straight into attic framing, eaves and furniture without any soil contact. It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Glendale is the western subterranean termite.
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 around Glendale tend to swarm in late summer and fall. Around Glendale, western subterranean termites usually swarm in spring, and again in fall after the first good rain. Swarm season is when termites show themselves.
Where to look around your house.
The same advice applies across the area, from Glendale out to Los Angeles and Long Beach. 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 Glendale sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Glendale.
- Spring and fall: swarm seasons. Around Glendale, swarms often follow the first warm days and the first fall rain. - Summer: with highs around 88°F in Glendale, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 21 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?
- 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. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Prep is light for liquid treatments and bait stations. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Glendale crew applies the product, and ask how long to stay off treated soil. In California, Reticulitermes swarm in the afternoon in spring or fall on clear days after a soaking rain; drywood swarmers fly in daytime during summer and fall; Heterotermes aureus flies late afternoon/early evening in July–September (UC IPM). Drill holes in slabs or patios get patched afterward.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Glendale that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- 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 product or system will you use? - Which termites did you find, and where?
What affects the price
- Slab, crawl space, or basement construction.
- Amount of drilling through concrete and patios.
- Warranty type: retreatment only or damage repair.
- Local labor rates and licensing requirements.
- Cubic footage under the tent for fumigation.
- Attached garages, decks, and additions.

What's your biggest concern about termites?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. 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.
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.

Simple ways to keep termites away
- Remove tree stumps and buried wood near the house.
- Inspect used furniture for drywood pellets before bringing indoors.
- Trim shrubs so foundation walls stay visible and dry.
- Keep the termite renewal contract current after treatment.
- Seal cracks in the foundation and slab.
- Address wood-to-soil contact at steps, fences, and trellises.

Questions people ask
How do I choose a termite company?
Compare the proposals, not just the totals. Ask what the warranty covers. Ask which termites they found and what product they'll use. Make sure they're licensed in California.
How long do termite bait stations take to work?
Then the bait spreads through the colony. Termites have to find the stations first. Usually several weeks to a few months.
Do I have to leave my house during termite treatment?
Everyone leaves for two to three days, pets and houseplants included. Fumigation is different. Not for a soil treatment or bait stations.
Will termites come back after treatment?
That's what yearly inspections and renewal plans are for. Treatments wear down and new colonies move in. They can.
Are mud tubes always a sign of active termites?
If it's rebuilt, they're active. Break off a piece and check back in a week. Old tubes can stay on a wall for years. Not always.
How much does a pre-construction termite treatment cost?
Professionals reported an average of $883. Anyone building a house can use $883 as a rough yardstick for pre-construction termite treatment, the professional-reported average in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents, 2024 pricing), while remembering that actual quotes depend on slab size, region and product.
How do I know if I have termites or ants?
Around Glendale, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around 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 California?
Around Glendale, the usual culprit is the western subterranean termite.
