Spring is winding down and summer is right around the corner — and in the Bay Area, that seasonal shift brings more than just warmer weather. It's also when termites, ants, rodents, and other household pests ramp up their activity as conditions become ideal for them to thrive.
The good news: a little proactive attention now can save you a lot of headache later. Here's a practical, room-by-room checklist for pest-proofing your Bay Area home before summer arrives.
Start Outside: Your Home's Exterior
The exterior of your home is your first line of defense. Most pests — termites included — find their way in from the outside, so this is where prevention starts.
Inspect and seal any cracks or gaps in the foundation.
Even small cracks in your foundation or exterior walls are an open invitation. Walk the perimeter of your home and look for gaps around pipes, utility lines, and vents. Seal them with caulk or appropriate filler material.
Pull mulch and soil away from the foundation.
Keep at least a 12 to 18 inch gap between mulch beds and your foundation. Mulch retains moisture and provides cover — two things subterranean termites love.
Check wood-to-soil contact.
Any wood that's in direct contact with soil — fence posts, deck supports, wood siding, or exterior stairs — is a prime termite entry point. Have a professional assess any areas where wood meets ground.
Clear gutters and check drainage.
Clogged gutters cause water to pool near your foundation, creating the moisture conditions that attract subterranean termites and other pests. Clean gutters now and make sure downspouts direct water away from the structure.
Trim trees and shrubs away from the house.
Branches touching your roof or siding give rodents and insects a direct path inside. Trim back any vegetation that's in contact with the structure.
Move firewood away from the house.
Store it at least 20 feet from the structure and off the ground. Firewood piles are a common harborage site for termites, ants, and rodents.
The Crawl Space
For Bay Area homes with crawl space foundations, this is one of the highest-risk areas for termite activity — and one of the most overlooked.
Check for moisture or standing water.
After our wet winter and spring, crawl spaces can retain moisture well into summer. Standing water or excessive dampness creates ideal conditions for both subterranean termites and wood rot.
Inspect your vapor barrier.
A vapor barrier on the crawl space floor helps prevent ground moisture from rising into the wood framing above. If yours is damaged, torn, or missing, now is the time to address it.
Look for mud tubes.
Subterranean termites build mud tubes along foundation walls, piers, and floor joists to travel between the soil and your home. Pencil-thin brown tubes running along surfaces are a clear sign of activity.
Check for soft or damaged wood.
Press on floor joists and sill plates. Soft, spongy, or visibly damaged wood could indicate termite activity or wood rot — and often both.
The Attic
Drywood termites love attics — warm, dry, and full of unfinished wood. Summer heat makes attic conditions even more hospitable.
Check attic vents for damage or gaps.
Attic vents are one of the most common entry points for drywood termites during swarming season. Make sure screens are intact and there are no gaps around vent frames.
Look for frass.
Drywood termite frass looks like small piles of sand or sawdust near wood surfaces. Finding frass in your attic is a strong indicator of active drywood termite activity.
Tap exposed framing.
Just like the wall knock test — tap exposed attic framing. A hollow sound where solid wood is expected warrants a closer look.
Ensure adequate ventilation.
Poor attic ventilation traps heat and moisture, which accelerates wood deterioration and creates conditions that pests find attractive. Make sure vents are unobstructed.
Interior: Kitchen, Bathrooms, and Utility Areas
Check under sinks for leaks or moisture.
Leaky pipes under kitchen and bathroom sinks create moisture that attracts pests. Check for any signs of water damage or dripping and address promptly.
Seal gaps around pipes and utility penetrations.
Any opening where pipes or wires enter your home from outside is a potential pest entry point. Use caulk or foam sealant to close these gaps.
Check window and door frames.
Drywood termites frequently enter through gaps around window and door frames. Look for any soft spots, discoloration, or frass near frames, and make sure weatherstripping is intact.
The Garage
Garages are often overlooked in pest prevention — but they're frequently the first place termites gain a foothold, especially in homes where the garage has wood framing adjacent to living spaces.
Don't store cardboard boxes on the floor.
Cardboard retains moisture and is an attractive harborage material for pests. Store items off the floor in plastic bins where possible.
Check the garage door seal.
A damaged bottom seal on your garage door leaves a gap that rodents, insects, and moisture can exploit. Replace worn seals promptly.
Inspect any wood storage or shelving.
Wood shelving, workbenches, or stored lumber in the garage can harbor drywood termites. Tap and inspect periodically, especially after swarming season.
The Most Important Item on the Checklist: Schedule a Professional Inspection
All of the above steps are valuable — but none of them replace a trained eye. A licensed termite inspector can identify conditions and activity that aren't visible to the untrained eye, catch infestations before they become expensive problems, and give you a clear, honest picture of your home's condition going into summer.
At Good Sense Termite, our inspections are always free. We cover the attic, crawl space, exterior, interior, and garage — and we walk you through every finding in plain language with no pressure and no upselling.
Call or text us at (408) 418-9152 or request your free inspection online before summer hits.
It's just good sense.
Frequently Asked Questions: Pest-Proofing Your Bay Area Home
When is the best time to pest-proof your home in the Bay Area?
Spring — right before summer — is the ideal window. Termite swarming season is active in spring, and taking preventative steps before the heat of summer sets in gives you the best chance of catching any issues early and addressing conducive conditions before they worsen.
How do I know if my crawl space has a moisture problem?
Signs include a musty smell coming from floors or vents, soft spots in flooring above the crawl space, visible condensation on pipes or wood, and standing water or excessive dampness when you look inside. A professional inspection will assess crawl space moisture as part of a standard termite inspection.
Can I pest-proof my home myself or do I need a professional?
Many of the exterior prevention steps — sealing cracks, trimming vegetation, managing mulch and firewood — are things homeowners can do themselves. However, identifying active termite infestations, assessing crawl space conditions, and treating any activity that's found requires a licensed professional. Think of DIY prevention as a complement to professional inspections, not a replacement.
How often should Bay Area homeowners inspect their attic and crawl space?
At minimum once a year. These are the two areas of a home most vulnerable to termite activity and moisture damage, and they're also the areas most homeowners never look at. An annual professional inspection covers both thoroughly.
Does pest-proofing prevent all types of termites?
Preventative measures significantly reduce your risk, but no home can be made completely termite-proof — especially in a high-activity region like the Bay Area. The goal of pest-proofing is to eliminate the conditions that make your home attractive and catch any activity early, before it becomes a larger problem.
What should I do if I find signs of termites during my own home check?
Don't disturb the area and call a licensed termite inspector as soon as possible. Disturbing an active colony can cause termites to scatter, making it harder to assess the full extent of the infestation. A professional inspection will give you a clear picture of what's happening and what treatment is needed.
