Think Termites Just Wander Into Homes? Think Again.
If you’ve ever wondered, “How did termites find my house out of all the homes on the block?”—the answer is simple: they’re following a very specific formula. These aren’t random pests. They’re biologically programmed to seek out the exact conditions that your home might be providing—whether you know it or not.
At Good Sense Termite, we’ve spent over 14 years inspecting homes across the Bay Area. We’ve seen termites target million-dollar remodels and modest cottages alike. It’s not about the age of the house—it’s about what it offers to termites: food, moisture, and access.
Let’s break down the science of how termites operate—and how we intercept them before they settle in.
How Termites Detect Their Ideal Environment
1. Chemical Detection Through Soil and Air
Subterranean termites (the most common in Northern California) rely on pheromones to find their way to food sources. These are chemical signals they lay in the soil as trails for other termites to follow. Once a worker termite locates damp wood, it sends the message back to the colony—“We’ve got a target.”
Drywood termites, which don’t need soil contact, use flight to seek out exposed wood. During swarming season, they’re drawn to homes by subtle cues like:
Sunlit, warm areas (especially windows and vents)
Cracks in siding or rooflines
Unsealed attic vents or soffit gaps
They don’t just stumble onto your property. They’re actively sensing and selecting.
2. Moisture: The #1 Attraction
Termites need moisture to survive—especially subterranean species. Damp areas around your home create perfect breeding grounds. Common triggers include:
Overwatered planters near siding
Leaky hose bibs or irrigation
Poor drainage near the foundation
Unventilated crawlspaces
Gutters overflowing onto the soil
A good rule of thumb: if it would attract a snail, it’ll probably attract termites.
3. Soil-to-Wood Contact = Fast Pass Entry
Any direct connection between wood and soil is a major risk factor. Termites don’t have to climb walls or squeeze through rooflines when there’s a shortcut from the ground. Examples include:
Fence posts and deck joists embedded in soil
Raised planter beds attached to siding
Old latticework buried in dirt
Wood formboards left in place after construction
These are stealth highways for termites to enter your home with zero resistance.
What Makes Bay Area Homes So Attractive?
Homes in the Bay Area are especially vulnerable because of:
Microclimates: Foggy coastal zones and damp foothill areas create consistent humidity and soil moisture.
Aging Housing Stock: Many homes were built before modern moisture barriers or flashing standards.
Landscaping Trends: Wood mulch, garden boxes, and drip irrigation make great termite habitats if placed too close to structures.
Crawlspaces and Stem Walls: Common construction types that offer hidden paths under the home, especially if left unsealed or poorly ventilated.
We’ve seen homes with extensive termite activity just a few years after brand-new siding or renovations—because the root problem wasn’t addressed.
How Good Sense Termite Stops the Process Cold
Our approach isn’t guesswork. It’s science-backed and field-tested.
✅ We Identify Attraction Points
Our licensed inspectors know exactly where and how termites choose a structure. During every inspection, we evaluate:
Moisture levels at the foundation
Drainage issues, standing water, or improper grading
Landscaping against the home
Cracks, vents, and other hidden entry points
Even if there’s no activity, we’ll flag every condition that might put your home at risk.
✅ We Treat the Right Species the Right Way
Termite control isn’t one-size-fits-all. Drywood and Subterranean termites behave differently, and we tailor your treatment accordingly:
Localized foam or injection for isolated Drywood colonies
Trenching and soil treatments for active Subterranean entry points
Spot treatments under decks, behind walls, or in attics—wherever signs or risks are found
We don’t overtreat—but we don’t cut corners either.
✅ We Offer Long-Term Protection Plans
Termite pressure doesn’t go away overnight. That’s why we offer custom warranty plans that fit the way your home is built and how termites might return.
And if they do? We’re already set up to handle it—no guessing, no panic.
FAQ: Termite Science for the Rest of Us
Why my house? The neighbors don’t have termites.
They might—they just don’t know yet. Termites are often invisible until damage is severe. Also, your home might have something they don’t: moisture, mulch, or access.
Are termites active year-round?
Yes. Swarmers fly in spring and summer, but colonies feed 24/7 all year—especially in crawlspaces and wall voids where it stays warm and damp.
Is fumigation always required?
Nope. Fumigation is only for certain Drywood infestations. Most termite issues can be addressed with localized or trenching methods, especially if caught early.
Final Thoughts: Termites Are Scientists, Too (Sort Of)
They might not wear lab coats, but termites are expert problem solvers. Their instincts, biology, and behavior patterns are shockingly efficient. That’s what makes them so good at finding homes—and what makes our job so important.
At Good Sense Termite, we stop termite science with termite common sense—and 14+ years of inspection experience to back it up.
