THE COMPLETE GUIDE TO TERMITE TREATMENT IN THE BAY AREA (2025 EDITION)

UNDERSTANDING THE TERMITE PROBLEM IN THE BAY AREA

Termites are among the most destructive pests facing Bay Area homeowners. The region’s mild coastal climate, consistent humidity, and abundance of wood-framed homes create the ideal environment for termite activity. Left untreated, termites can compromise structural integrity, reduce property value, and lead to costly repairs.

​

In California, termites cause hundreds of millions of dollars in damage every year. Bay Area homeowners are particularly vulnerable because both Drywood and Subterranean termite species thrive here.

 

That’s why choosing a licensed, local expert like Proven Termite Solutions is critical. With over 30 years of experience specializing in fumigation, we provide thorough, long-term protection for homes across the South Bay, Peninsula, and East Bay.

COMMON TERMITE SPECIES IN THE BAY AREA

DRYWOOD TERMITES​


Drywood termites live directly inside wood structures such as framing, rafters, furniture, and hardwood floors. They do not require soil contact or high moisture, making them common in attics and upper floors. Because they stay hidden within wood, infestations often go unnoticed until damage is advanced.

Drywood termites are best treated with fumigation, which penetrates deep into wood and eliminates colonies throughout the structure.
 

Key Signs:
 

  • Small piles of pellets (frass) near windows or baseboards

  • Hollow-sounding wood

  • Buckled paint or blistered surfaces

Drywood Termites

SUBTERRANEAN TERMITES

​

These termites live underground and travel through mud tubes to access wood, often entering homes through tiny cracks in the foundation or expansion joints. They are highly destructive, forming massive colonies that can silently consume the structural wood of a home, damaging beams, flooring, and even interior walls before visible signs appear. Because their colonies can number in the millions, damage can progress quickly once they gain access. Subterranean infestations are often treated with soil injection, creating a long-lasting chemical barrier around the foundation that not only eliminates active colonies but also prevents future infestations from returning.

 

Key Signs:

 

  • Mud tubes along walls or foundations

  • Damaged wood with layered patterns

  • Excess moisture or leaks near entry points

Subterranean Termites

DAMPWOOD TERMITES (LESS COMMON)

​

Dampwood termites infest wet, decayed wood and are often found in areas with excess moisture or poor ventilation. They thrive around leaky plumbing, water-damaged floors, or wooden structures exposed to constant humidity. Unlike Drywood or Subterranean termites, Dampwood termites do not need contact with soil but rely heavily on moisture to survive. They feed on softened, decaying wood, gradually hollowing it out and weakening the structure over time. While less common in most Bay Area homes, they can still cause significant damage if leaks, poor drainage, or ventilation problems are ignored. The most effective prevention is moisture control through leak repair, proper ventilation, and maintaining dry conditions around wooden areas of the home.

 

Key Signs:

 

  • Soft, decaying, or water-damaged wood with smooth interior galleries

  • Presence of large winged termites near moisture-prone areas

  • Wood that feels damp or emits a musty odor when disturbed

RECOGNIZING THE SIGNS OF TERMITE INFESTATION

Early detection is key to minimizing damage.

 

Look for:

 

  • Hollow-sounding wood or sagging floors

  • Tiny holes or grooves in walls and trim

  • Frass resembling sawdust

  • Discarded wings near windows

  • Mud tubes on foundations

  • Stuck doors or windows from warped frames

 

If you notice any of these, schedule an inspection right away. See our What to Expect from a Termite Inspection article for details on how we identify and assess infestations.

TREATMENT OPTIONS FOR BAY AREA HOMES

At Proven Termite Solutions, we provide tailored treatments based on infestation type and severity.

BEST TERMITE TREATMENT OPTIONS FOR BAY AREA HOMES

The best termite treatment for a Bay Area home depends on the type of termite, the size of the infestation, and the construction of the structure. Drywood termites often require whole structure fumigation because the gas reaches hidden colonies inside walls, attics, and wood framing. This provides full coverage and is the most reliable option for advanced or widespread infestations. Subterranean termites usually call for soil injection treatments, which create a long lasting barrier around the foundation and stop termites from entering the home. Some localized infestations can be treated with targeted spot applications, including products like Termidor or orange oil for limited Drywood activity. A licensed inspector can determine the right approach by evaluating species, damage, and risk factors for your property. Choosing the correct treatment ensures faster elimination, long term protection, and fewer retreatments over time.

FUMIGATION: THE GOLD STANDARD

 

Fumigation is the most effective solution for widespread Drywood termite infestations. The process encloses the entire structure and introduces Vikane gas, which penetrates walls, floors, and inaccessible areas to eliminate all termites.

 

Benefits:
 

  • Reaches all areas of the home

  • Complete colony elimination Ideal for severe infestations

  • Fast, typically 3 days from start to finish

LOCALIZED TERMITE CONTROL

​

For smaller, isolated infestations, localized treatments can target specific problem areas. We use professional products like Termidor® and Orange Oil, depending on the location and severity.
 

Advantages:

 

  • Lower cost for limited infestations

  • Minimal disruption

  • Targeted application

SOIL INJECTION TREATMENT

​

Designed for Subterranean termites, this treatment involves applying a liquid termiticide deep into the soil surrounding the home’s foundation, slabs, and entry points where termites are likely to travel. The product penetrates the soil to form a continuous chemical barrier that not only kills termites on contact but also prevents new colonies from invading. This method is especially effective for long-term protection because it targets the source of the problem underground, where termite colonies originate and thrive. When properly applied by a licensed technician, soil injection treatment provides a durable defense that safeguards your property’s structure and foundation from future infestations.

Soil Injection Application

ORANGE OIL TREATMENT

​

Orange Oil treatment is a popular alternative for homeowners seeking a more natural or eco-friendly termite solution. Derived from the rinds of oranges, this essential oil contains d-limonene, a compound proven to kill Drywood termites and their eggs on contact. Unlike traditional fumigation, Orange Oil treatments target specific localized infestations without requiring homeowners to vacate the property or remove food and plants. It is an excellent choice for environmentally sensitive situations, historic homes, or spaces where full-structure tenting isn’t practical. While it is best suited for smaller infestations, Orange Oil can be an effective part of an integrated termite management plan when combined with professional inspection and prevention methods.

TERMITE TREATMENT COSTS IN THE BAY AREA

Termite treatment costs in the Bay Area can vary widely depending on several key factors. The size and type of structure play a major role, as larger homes or multi-unit buildings require more time, labor, and materials. The extent of infestation is equally important since localized issues can often be treated more affordably than widespread or severe infestations that require full-structure fumigation. The treatment method selected, such as fumigation, localized control, soil injection, or orange oil, also affects pricing based on the scope and equipment involved.

Other factors include accessibility, such as whether areas of infestation are easy to reach or hidden within walls, attics, or crawl spaces, and any preparation needed before treatment. The inclusion of a warranty and follow-up service can also influence the total cost but provides long-term value by ensuring continued protection and peace of mind.

At Proven Termite Solutions, we provide free inspections and clear, upfront quotes before beginning any work. Our goal is to help homeowners understand their options and choose the most effective and affordable solution for lasting results.

PREVENTING FUTURE INFESTATIONS

Treatment is only part of the solution. Long-term protection comes from ongoing prevention and maintenance. Once termites have been removed, it is essential to address the conditions that allowed them to thrive in the first place. Preventive measures not only keep your home termite-free but also reduce the likelihood of future structural damage and costly repairs.

Key Steps:
 

  • Eliminate moisture sources: Termites are attracted to damp environments. Fix leaky pipes, faulty sprinklers, or drainage issues that create excess moisture near your home’s foundation.

  • Repair leaks and improve ventilation: Proper airflow in crawl spaces, attics, and basements helps keep wood dry and unappealing to termites. Installing vents or dehumidifiers can be effective for long-term prevention.

  • Avoid direct wood-to-soil contact: Keep wooden siding, decks, and fencing raised above ground level to prevent easy access points for Subterranean termites.

  • Schedule regular professional inspections: Periodic inspections by a licensed termite specialist ensure that early signs of activity are detected before major damage occurs.

  • Trim vegetation away from exterior walls: Keep bushes, trees, and mulch a safe distance from your foundation to improve airflow and limit hidden entry paths.

Consistent monitoring and maintenance are key to protecting your home’s structure and value. For additional guidance and practical homeowner tips, see our Termite Prevention for Homeowners article.
