October is nearly over, and the Bay Area's wet season is underway. For homeowners, this is the natural moment to take stock of where things stand — before the holiday pace picks up, before December rain events test the drainage, and before another year of potential termite activity closes out without a record of what was done.
This checklist covers the key termite and moisture-related items worth confirming before winter sets in. It's not exhaustive — it's focused on the things that matter most for Bay Area homes specifically, and that are easiest to let slip through the end-of-year shuffle.
Work through it room by room, exterior first, then inside and below.
Exterior Checklist
Foundation Perimeter
Walk the full foundation perimeter and look for mud tubes. After the first significant rains, subterranean termite foraging picks up sharply. New mud tubes — thin, brown, pencil-width tunnels running up foundation concrete or wood — that weren't present before the rains indicate active foraging. Note any you find and call for an inspection.
Check soil grade around the foundation. Soil that slopes toward the foundation traps moisture against it. Look for areas where mulch, soil, or decomposed organic material has built up against the foundation or siding — clear it back to maintain at least a 6-inch gap between soil and any wood elements.
Confirm there's no wood-to-soil contact. Fence posts, deck supports, garden bed borders, and stored lumber in contact with the soil adjacent to the house are subterranean termite bridges. Address any direct contact you find.
Exterior Wood Surfaces
Inspect all painted and unpainted exterior wood. Eave boards, fascia, window frames, door frames, siding, and any decorative trim. Look for blistered or bubbled paint (can indicate drywood termite galleries beneath), soft spots when pressed, and frass accumulation in joints and ledges.
Check the deck or back porch. Test boards by pressing firmly with your heel — any that give more than expected may be compromised by termite damage or rot. Check posts at ground contact, the ledger where the deck attaches to the house, and any railings with wood-to-wood joints.
Look for drywood termite exit holes. Small, round holes (1/16 to 1/8 inch diameter) in exterior wood are where swarmers have emerged. Swarming season has ended but the holes remain — fresh holes from this year's swarmers indicate colonies that established or expanded over the summer.
Drainage and Moisture Points
Clear gutters and confirm downspout drainage moves water away from the foundation. Overflowing gutters deposit water directly against the foundation; downspouts that terminate too close to the house keep the soil saturated. Both create conditions that favor subterranean termite activity.
Check crawl space vents are clear and unobstructed. Fall leaf accumulation and debris can block foundation vents. Adequate ventilation is critical for managing crawl space humidity through the wet season.
Look for any plumbing drips or leaks on the exterior. A slow drip from an outdoor faucet or irrigation connection that's been running all summer has created a moisture zone in the adjacent soil. Repair and allow it to dry before winter rains compound the saturation.
Fencing
Check fence post bases with a screwdriver. Press firmly into each post at soil level — soft or easily penetrated wood indicates rot or termite damage. Look for mud tubes running up post surfaces.
Confirm no fence sections have settled to soil contact. Boards that now touch the ground are newly accessible to subterranean termites.
Crawl Space Checklist
The crawl space is where winter termite activity is most consequential — and least often checked. If you're able to safely access yours, or if your last professional inspection noted any conditions worth monitoring, this is the section that matters most.
Confirm the vapor barrier is intact and in place. A compromised vapor barrier allows ground moisture to evaporate directly into the crawl space, raising humidity and creating conditions that favor both termite activity and wood rot. Look for tears, gaps at foundation walls, or sections that have been moved and not replaced.
Check for standing water or significant moisture accumulation. After the first heavy rains, water can accumulate in crawl spaces with drainage issues. Standing water in the crawl space is an urgent condition — it needs to be addressed before the wet season continues.
Look for new mud tube construction on piers and joists. This is the most direct evidence of active subterranean termite activity. Any mud tubes that weren't present at your last inspection — or that have been rebuilt after being broken — indicate active foraging.
Note any wood that looks darker, softer, or differently textured than surrounding framing. Early-stage subterranean termite damage and moisture-related wood deterioration are both worth documenting and having assessed professionally if found.
Interior Checklist
Room by Room
Tap baseboards in rooms that don't see heavy daily use. Guest rooms, formal dining rooms, home offices in older parts of the house. Hollow-sounding baseboards can indicate drywood termite galleries in the wall framing behind them.
Check window and door operation throughout the house. Doors or windows that have started sticking or that no longer sit square in their frames — without a moisture or paint explanation — can indicate termite damage to the framing.
Look for frass accumulations on windowsills and below wall fixtures. Clean any frass you find and note the location — if it reappears, the colony is active.
Walk slowly through every room and listen to the floor. A spongy, springy, or hollow-sounding floor section that wasn't there before is worth having inspected, particularly in rooms above the crawl space.
Attic
If you can safely access your attic, look at the framing with a flashlight. Drywood termites in attic framing often show as frass accumulation on top of insulation or on the attic floor, visible galleries in exposed framing members, or damaged wood that looks lighter or more papery than sound framing.
Check that attic vents are clear. Blocked attic vents raise humidity, which creates conditions that favor drywood termite colony development.
Garage
Check the garage slab for new cracks and the gap at the wall framing base for mud tubes. Garage slabs are a common subterranean entry point.
Clear any wood stored directly on the concrete floor. Lumber, firewood, cardboard boxes, and wood furniture stored at slab level provide both food and a pathway for subterranean termites to access the structure.
Documentation Checklist
Confirm you have a current WDO report on file. If your last inspection was more than 12 months ago, schedule one before year-end. An annual inspection creates the documented maintenance record that matters for real estate transactions, insurance discussions, and your own peace of mind.
Locate and review your termite treatment warranty. Know your current warranty status, expiration date, and what's covered. Many warranties require annual inspection to remain valid.
Note anything you found during this checklist for your inspector. Specific observations — a frass location, a suspicious floor section, a new mud tube — are genuinely useful for an inspector and can direct their attention to findings they might spend additional time reaching on their own.
If Your Checklist Turns Up Concerns
This checklist isn't designed to replace a professional inspection — it's designed to help you get to that inspection with specific, useful observations rather than a vague sense that something might be wrong.
If you've worked through this list and found one or more items that concern you, or if it's simply been more than a year since your last inspection, now is the right time to call. October and early November are practical scheduling windows — before holiday commitments fill the calendar and before winter rains drive up demand for crawl space assessments.
Good Sense Termite offers free inspections throughout Santa Clara County, year-round. Call or text us at (408) 418-9152 or request your free inspection online. We'll work through what you've found and give you a clear, honest picture of your home's status going into winter.
It's just good sense.
Frequently Asked Questions: Year-End Home Maintenance and Termites
Why is fall a good time to do a termite-focused home inspection?
Fall is the convergence of two important seasonal moments: drywood swarming season has just ended, meaning any new colonies established over summer are now active and detectable, and the first winter rains are beginning, which drives increased subterranean termite foraging near foundations and in crawl spaces. An inspection in October or November captures both species at peak detectability and gives you time to act before the holidays and before winter damage accumulates.
How long does a thorough termite-focused home walkthrough take?
The exterior and interior walkthrough described in this checklist typically takes 20 to 30 minutes for a single-family home if you work through it methodically. The crawl space, if accessible and in reasonable condition, adds another 15 minutes. This is a homeowner-level check — it's not a substitute for a professional inspection, but it gives you specific observations to bring to one.
What should I do with firewood stored near the house over winter?
Move it. Firewood stacked against or very close to the house creates both a moisture zone and direct wood-to-soil-to-house contact that subterranean termites can exploit. Store firewood at least 20 feet from the house, elevated off the ground on a rack, and away from any soil that's in contact with the foundation. Bring in only what you'll burn within a few days rather than storing a full supply indoors.
Is a vapor barrier in the crawl space really necessary?
Yes, for most Bay Area homes with conventional crawl spaces. The ground beneath a home releases moisture continuously, and without a vapor barrier, that moisture evaporates into the crawl space air, raising humidity and creating conditions that favor both subterranean termite activity and wood rot in the framing above. A well-maintained vapor barrier covering the ground is one of the most effective single measures for protecting a Bay Area home's crawl space framing through the wet season.
What does my termite warranty actually cover, and what do I need to do to keep it valid?
Warranty terms vary by company and treatment type, but most termite treatment warranties cover re-treatment at no additional cost if the treated species reappears within the warranty period, provided certain maintenance conditions are met. Most warranties require annual inspection to remain valid. Read your specific warranty document to understand the coverage period, what's required to keep it active, and whether it covers repair costs or only re-treatment. If you've lost your warranty documentation, call the company that performed the treatment.
Should I get a termite inspection even if I haven't noticed any signs?
Yes — particularly in a pre-1980 Bay Area home. Both drywood and subterranean termites can maintain active colonies for extended periods without producing obvious signs visible to homeowners. Annual professional inspection is the only reliable way to catch activity before it reaches the point where signs become apparent on their own — and catching it early is almost always significantly less expensive than addressing it after it's obvious.
