Homeowners, landlords and anyone buying or selling a house in Santa Clarita, 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. Average winter lows near 40°F slow termites near the surface around Santa Clarita, but they move deeper and keep feeding under heated homes. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Dry hexagonal pellets under window frames or eaves.
- 2Piles of identical shed wings on windowsills.
- 3Sagging or spongy floors near exterior walls.
- 4Discarded wings caught in spider webs.
- 5Screwdriver sinks easily into sills or trim.
- 6Doors and windows that suddenly stick.
Why it’s worth acting soon

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 Santa Clarita 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 Santa Clarita, on a slab, the crew treats the soil along the outside walls.
Which termites live around Santa Clarita.
They'll eat fences, door frames, anything wooden. In Santa Clarita's dry heat, desert subterranean termites can build tubes that hang free from ceilings. Look for tiny piles of pellets that look like coarse sand. Drywood termites are common around Santa Clarita 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 Santa Clarita is the desert subterranean termite.
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.
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 Santa Clarita tend to swarm in late summer and fall. Around Santa Clarita, 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 Santa Clarita out to Glendale and Los Angeles. 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 Santa Clarita sit on concrete slabs, so termites come up through expansion joints, plumbing gaps and settlement cracks.
A year of termites in Santa Clarita.
- Summer: swarm season in Santa Clarita, usually after monsoon storms. Watch porch lights at dusk. - Summer: with highs around 95°F in Santa Clarita, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 18 inches of rain a year in Santa Clarita, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Santa Clarita, 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 Santa Clarita 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 Santa Clarita's dry climate the risk is irrigation and leaky hose bibs rather than rain. 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.
- Extent of existing damage needing repair.
- Time of year and how booked up local companies are.
- Annual renewal and monitoring fees.
- Whole-house fumigation versus spot treatment.
- 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
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. 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.
