Nobody invites termites in on purpose. But every year, Bay Area homeowners unknowingly make their homes more attractive to termites through a handful of common habits and oversights. The good news: most of these are easy to fix once you know about them.

Here are five of the most common things we see during inspections that give termites exactly what they're looking for.

1. Storing Firewood Against the House

We get it — keeping a woodpile next to the back door is convenient. But firewood stacked directly against your home is essentially a welcome mat for subterranean termites. Wood-to-structure contact gives termites a direct highway from an outdoor food source right into your home's framing, with no exposed ground to cross.

The fix is simple: store firewood at least 20 feet away from the house and elevated off the ground on a rack or pallet. Use your woodpile on a first-in, first-out basis so older wood at the bottom doesn't sit long enough to become a termite colony.

2. Letting Mulch Touch the Foundation

Mulch is great for gardens — it retains moisture, regulates soil temperature, and keeps weeds down. But when it's piled up against your foundation, it creates a moist, dark environment right next to your home that subterranean termites love. Many types of wood-based mulch are also a food source in their own right.

The fix: keep a 12 to 18 inch gap between mulch beds and your foundation. If you want extra protection, use rubber mulch or gravel in the zone directly adjacent to the house — materials termites have no interest in.

3. Ignoring Moisture Issues in the Crawl Space

Bay Area homes with crawl space foundations are particularly vulnerable to subterranean termites, and moisture is a big reason why. Subterranean termites need humidity to survive, and a damp crawl space is one of the most hospitable environments they can find. Standing water, condensation on pipes, and poor ventilation all contribute to the problem.

The fix: make sure your crawl space has adequate ventilation and that any plumbing leaks are addressed promptly. A vapor barrier installed on the crawl space floor significantly reduces ground moisture. If you haven't looked under your house in a while, now is a good time — or call us and we'll take a look for you.

4. Leaving Dead Wood on the Property

Tree stumps, old fence posts, scrap lumber left over from a renovation, a fallen branch that's been sitting in the yard since last winter — all of these are termite buffets. Subterranean termites will readily establish a colony in decaying wood on your property, and once a colony is established nearby, your home becomes the next logical target.

The fix: remove dead stumps and decaying wood from your property, especially anything within 20 to 30 feet of the house. If stump removal isn't feasible, a termite professional can treat the area. And after any home project, don't let scrap lumber linger — dispose of it promptly.

5. Skipping Annual Inspections

This one might be the most common — and the most costly. Termite infestations are silent by nature. You can have an active colony quietly destroying wood inside your walls for years with no visible signs until the damage is significant. Many Bay Area homeowners only call a termite company when something looks obviously wrong, by which point treatment is more extensive and repairs are more expensive.

The fix: schedule a termite inspection once a year, even if you haven't seen any signs of activity. An annual inspection takes an hour or two and costs nothing with Good Sense Termite — and it gives you the peace of mind of knowing what's actually happening inside your home's structure before it becomes a bigger problem.

The Bottom Line

Termites don't need an open door — they need opportunity. Firewood against the house, mulch at the foundation, a damp crawl space, dead wood in the yard, and skipping annual checkups are all opportunities you can take away from them with relatively simple changes.

If you're not sure whether your home has any of these conditions, we're happy to take a look. Call or text Good Sense Termite at (408) 418-9152 or request your free inspection online. We'll walk through your property and flag anything that could be putting your home at risk.

It's just good sense.

Frequently Asked Questions: What Attracts Termites to Your Home

What is the number one thing that attracts termites to a house?

Moisture is the single biggest attractant for subterranean termites, which are the most common species in the Bay Area. Damp crawl spaces, wood-to-soil contact, and poor drainage around the foundation all create ideal conditions. For drywood termites, exposed or unfinished wood on the exterior of the home is the primary entry point.

Does mulch attract termites?

Wood-based mulch can attract termites, particularly when it's piled against the foundation of a home. The combination of moisture retention and organic material creates a hospitable environment. Keeping mulch at least 12 to 18 inches away from the foundation significantly reduces the risk.

How far should firewood be stored from the house to prevent termites?

At least 20 feet away from the structure, and elevated off the ground. The further the better — the goal is to eliminate any direct path between the woodpile and your home's framing.

Can termites come from a neighbor's yard?

Yes. Subterranean termite colonies can spread underground across property lines, and drywood termites can swarm from a neighboring structure and infest yours. Living in a densely populated neighborhood — which much of San Jose is — means your termite risk is partially tied to what's happening on adjacent properties.

How often should I get a termite inspection in the Bay Area?

Once a year is a good standard for Bay Area homeowners, given our climate and the prevalence of both drywood and subterranean termites in the region. Homes with crawl space foundations, older construction, or a history of termite activity may benefit from more frequent checks.

Does landscaping affect termite risk?

Yes. Beyond mulch, other landscaping choices can affect termite risk — things like planting bushes or shrubs too close to the foundation (which traps moisture), having irrigation that sprays directly onto the house, or leaving tree limbs in contact with the roof or siding. A termite inspection will flag any landscaping conditions that are contributing to your risk.
