Subterranean termites most often damage the parts of a home you rarely see: crawl spaces and basements, wall voids, and attic framing that stays damp from roof or gutter leaks. Their soft, unsclerotized bodies lose moisture quickly in open air, and subterranean termites require moist environments, so these wood-destroying insects stay in soil, inside wood and in the mud tubes they build. That is why they seek out covered, damp and secluded areas, and why termite damage often goes unnoticed until it is advanced.
Saela Pest Control is a residential and commercial pest control company, based in Orem, Utah, that began as Edge Pest Control in 2008 and has completed more than 4 million services since then. Below are the main termite hotspots in a home, why termites target hidden structural wood first, and what you can check to lower the risk.
Crawl Spaces and Basements
Crawl spaces and basements are usually the first areas subterranean termites reach. These termites nest in the soil and reach wood that touches the ground or travel to it through earthen shelter tubes. Crawl spaces and unfinished basements combine the conditions they need: darkness, moisture and wood close to the ground. The 50+ point property inspection included in every Saela plan covers structural gaps, attics and basements.
In many homes, these lower levels are where wood is most likely to touch soil or stay damp, such as support beams resting on a foundation that wicks moisture from the ground, or floor joists a few inches above damp dirt. Because homeowners rarely go into these spaces, an infestation can grow undisturbed for years. Older homes deserve extra attention here; see what to check before buying an older home.
Wall Voids
Termites rarely stop at the foundation. They build mud tubes to travel into the upper structure of a house, including wall voids. Wall voids are insulated against temperature swings, protected from predators and shielded from sunlight, so a colony can feed there for long periods without being seen.
Termites eat studs, sill plates and load-bearing framing from the inside out while leaving the surface intact, so a wall can look normal while the wood inside it is damaged. Knowing the early signs of termite damage most homeowners miss helps you catch activity before it reaches this stage.
Attics and Roof Lines
Termites don’t only attack the lower levels of a home. Subterranean termites can travel up to an attic if they find a reliable moisture source, such as a leaky roof, a poorly sealed chimney or an overflowing gutter that soaks trusses and joists. Attics and tight crawl spaces are also hard places to search, with nails, dust or standing water, which is why University of California IPM guidance recommends having a licensed professional do the inspection. If you hire someone, check their credentials first: Saela is a member of the National Pest Management Association and is listed in QualityPro’s directory of accredited pest-control companies.
Why Hidden Structural Components Are Targeted First
Termites stay hidden instead of eating exposed wood on the outside of your home because of their biology. Subterranean termites dry out quickly in open air and sunlight, so they need a humid, enclosed environment to survive. Hidden wood gives them moisture, shelter and food in the same place.
Framing behind drywall and joists under floors provide that protection. By eating wood from the inside and leaving a thin layer of wood or paint on the surface, termites stay shielded from dry air and predators while they feed. That is why significant structural damage often happens before a homeowner sees any warning signs, and why finding it depends on knowing where termites live rather than waiting for visible damage. At Saela, pest-control protocols are developed by Dennis Weiss, BCE, Saela’s board-certified entomologist, who also trains its technicians and audits service quality.
Inspection Priorities to Reduce Termite Risk
Because termites are hard to spot, prevention and regular inspection are the best defense. University of Kentucky extension guidance on protecting your home from termites centers on the same basics: remove wood-to-soil contact, control moisture and watch for mud tubes. Saela’s integrated pest management approach starts in the same place, by identifying the pest and the conditions that support it, then monitoring activity, treating where needed and adjusting based on the results. Prioritize these checks:
- Check for wood-to-soil contact: Walk the perimeter of your home and make sure no wooden siding, deck posts or structural supports touch the soil. Wood siding and door and window frames should sit at least six inches above ground level.
- Manage excess moisture: Divert water away from your foundation with working gutters, downspouts and splash blocks. Ventilate your crawl space, cover exposed soil with a vapor barrier, and repair plumbing leaks and foundation cracks promptly.
- Inspect vulnerable areas routinely: With a flashlight, check basements, crawl spaces and attics. Look for pencil-wide mud tubes along foundations, piers, sills and joists, sagging floors, or wood that sounds hollow when tapped.
- Clear debris: Keep firewood, lumber, cardboard and other wood debris away from your foundation, and keep mulch from touching wood siding or framing.
How Saela Inspects and Treats Termites
If an inspection finds termite activity, Saela’s termite control packages use Trelona bait stations, and the upgraded package adds a Termidor perimeter treatment, with inspection schedules and re-treatment coverage set by the plan you choose. Because a termite plan involves scheduled visits over time, it helps to know how a company shows up: in a February 2024 Google review, Mark Lovgren wrote, “They showed up when they said they would.” On Google, Saela’s American Fork, Utah location is rated 4.9 out of 5 from 118 reviews as of October 2026.
If you’ve found mud tubes, hollow-sounding wood or persistent moisture in any of these areas, book a call to schedule a termite inspection. As of October 2026, Saela’s Orem, Utah headquarters is accredited by the Better Business Bureau with an A+ rating.
