Let's talk about the question almost every homeowner has but sometimes feels awkward asking: how much is this actually going to cost?
It's a fair question, and you deserve a straight answer. Termite treatment costs in the Bay Area vary quite a bit depending on the type of termite, the extent of the infestation, and the treatment method involved. We're going to break it all down here — no vague ranges, no bait-and-switch — so you know what to expect before you ever pick up the phone.
Why Termite Treatment Costs Vary So Much
If you've searched online for termite treatment costs, you've probably seen ranges so wide they're almost useless ("$200 to $10,000!"). The reason for that range is real: termite treatment isn't a one-size-fits-all service. The cost depends on several factors:
Type of termite (drywood vs. subterranean require completely different treatments)
Extent of the infestation (localized vs. whole-home activity)
Treatment method (spot treatment, fumigation, soil treatment, bait systems)
Size of the home
Accessibility (crawl space height, attic access, construction type)
With that context, here's a realistic breakdown of what treatment typically costs in the San Jose and Bay Area market.
Drywood Termite Treatment Costs
Drywood termites are typically treated one of two ways: localized spot treatments or whole-structure fumigation (tenting).
Spot / Local Treatment
If the infestation is caught early and confined to a specific area — say, one section of attic framing or a window frame — a localized treatment may be appropriate. This involves drilling and injecting termiticide directly into the infested wood.
Typical cost range: $900 – $1,800 depending on the number of treatment areas and accessibility.
Whole-Structure Fumigation (Tenting)
When drywood termite activity is widespread throughout a home — multiple locations in the attic, walls, or framing — fumigation is the most thorough and reliable option. Your home is sealed under a tent and filled with a gas (sulfuryl fluoride) that penetrates all wood throughout the structure.
Typical cost range: $1,500 – $4,000+ for most Bay Area homes, based on the cubic footage of the structure. Larger homes, multi-story buildings, or homes with complex rooflines will be on the higher end.
Note: Fumigation requires you to vacate your home (and any pets) for approximately 24–72 hours, which is an additional logistical consideration.
Subterranean Termite Treatment Costs
Subterranean termites require a different approach entirely — treating the soil around and beneath your home to eliminate the underground colony.
Liquid Soil Treatment
A termiticide is applied to the soil along the foundation perimeter and, where applicable, beneath the slab or in the crawl space. This creates a treated barrier that kills termites as they travel.
Typical cost range: $800 – $2,500 for most San Jose area homes, depending on linear footage of the foundation and crawl space conditions.
Bait Systems
Bait stations are installed around the perimeter of the home and monitored over time. Termites find the bait, carry it back to the colony, and the colony is eliminated over weeks to months. Bait systems require ongoing monitoring visits.
Typical cost range: $1,000 – $2,500 for initial installation, plus annual monitoring fees.
What About Repairs?
Treatment addresses the live termites — but it doesn't repair damage that's already been done. If termites have compromised structural wood (floor joists, sill plates, framing), repairs may be needed after treatment. Repair costs are highly variable and depend on the extent of the damage, but it's worth asking your inspector to flag any areas of concern during the inspection so you have a full picture.
This is one more reason why catching termite activity early matters so much — the treatment cost stays manageable, and you avoid the much steeper cost of structural repairs.
Does Homeowners Insurance Cover Termite Treatment?
In most cases, no. Standard homeowners insurance policies in California exclude termite damage and treatment, classifying it as a maintenance issue rather than a sudden or accidental loss. A few specialty policies exist, but they're not common. This is why preventative inspections and early detection are so important — treatment is significantly less expensive when an infestation is caught before it causes major damage.

Frequently Asked Questions: Termite Treatment Costs in the Bay Area
Q: Is a termite inspection free?
A: At Good Sense Termite, yes — inspections (if not for escrow purposes) are free. We'll assess your entire home and give you a full written report of our findings with no obligation to proceed with treatment.
Q: How do I know if I need fumigation or just a spot treatment?
A: That determination is made during the inspection. The key factors are the species of termite, how widespread the activity is, and whether it's accessible enough for localized treatment. We'll give you an honest recommendation based on what we find — not the most expensive option by default.
Q: Does termite treatment cost more for larger homes?
A: Yes, in most cases. Fumigation is priced by cubic footage, and soil treatments are priced by linear footage of the foundation. Larger or multi-story homes will generally cost more to treat.
Q: How long does termite treatment last?
A: This depends on the treatment type. Fumigation eliminates all drywood termites present at the time of treatment but does not prevent future infestations. Soil treatments for subterranean termites typically carry a warranty of one year or more with the option to renew. Good Sense Termite provides warranty coverage on all completed treatments — ask us about the specifics for your situation.
Q: Can I get multiple quotes before deciding?
A: Absolutely. We encourage it. Getting two or three quotes is a smart move for any significant home service. Just make sure each company is doing a real inspection before quoting — any company that gives you a price over the phone without seeing your home is guessing.
Q: What payment options are available?
A: Contact us directly at (408) 418-9152 to discuss payment options. We work with homeowners to make treatment as accessible as possible.
