Much of Santa Ana was built before 1960, and a large share of its housing is wood-frame with stucco or wood siding. For drywood termites, these buildings are about as welcoming as it gets: seasoned timber, small gaps in old trim, and a climate that never gets cold enough to interrupt activity.
Why Santa Ana houses draw termites
In districts like Floral Park, French Park, Lacy and Willard, original framing lumber, plus decades of patch repairs, create plenty of hidden entry points. Older fascia boards, loose eave returns, vent screens that have rusted through, and cracked window sills all let in swarming reproductives. Detached garages and back units share the same issues. Drywood swarms in Orange County are often noticed in the warm days of late summer and fall.
Subterranean termites also live in Orange County soils. They tend to be found where wood touches ground, near leaks or where planter boxes press against walls, and are a particular concern in crawlspace homes and porches.
Evidence that termites are active
- Tiny, hard pellets resembling coarse sand or coffee grounds beneath wood trim, in window tracks or on garage shelves.
- Wings scattered on sills after a swarm.
- Pin-sized holes in wood surfaces, sometimes sealed with a speck of material.
- Mud tubes on stem walls or crawlspace piers, which signal subterranean species.
- Paint that bubbles over wood without any water source.
Treatment choices licensed providers discuss
An inspection covers the attic, eaves, garage, crawlspace and the exterior trim. For drywood termites spread through multiple areas, fumigation is a standard whole-structure approach. For limited activity, spot treatments with injected products, foam or heat can be an option. For subterranean termites, a perimeter soil treatment or bait stations are typical, and fixing the water source is essential.
Duplexes and fourplexes pose a special case. Because the units share one structure, a fumigation requires every household to prepare and leave on schedule. Owners should line up tenants, utilities and notices early.
Home sale inspections
Buyers of older Santa Ana homes commonly order a termite report. If it flags work, sellers and buyers negotiate who handles it, and the report often lists areas where wood is in contact with soil or moisture.
One practical point for Santa Ana owners: keep the paperwork. Termite reports, treatment certificates and any notes about repaired wood become valuable when you sell, refinance or compare quotes from different providers. If your property has an older addition or a back house, mention it when you schedule, so the inspector knows to examine every structure on the lot.
Protecting an older home
- Replace damaged fascia, trim and window sills, then paint all exposed wood.
- Screen attic and foundation vents with fine metal mesh.
- Keep soil, mulch and plants clear of the stucco weep line and siding.
- Do not store wood against walls or inside crawlspaces.
- Fix leaks in plumbing and roofs promptly.

Santa Ana termite FAQ
Can termites live in a house with a concrete foundation?
Yes. A concrete foundation does not stop drywood termites, which enter above ground, and subterranean termites use cracks.
Do I need to remove food for fumigation?
Items not in sealed original containers are typically bagged or removed. The provider supplies a list.
How can I tell if damage is old?
Only an inspector can say reliably, but fresh pellets or live insects indicate activity.
Are termites covered by homeowner insurance?
Generally no. Check your policy and talk to your insurer.
