Cost is usually the first practical question homeowners ask after a termite diagnosis, and it’s a fair one. Termite treatment isn’t a fixed-price service. The cost varies based on which treatment method is appropriate, the size of the home, the extent of the infestation, and the specific species involved. A localized spot treatment for a single window frame costs a fraction of what a whole-structure fumigation costs for a larger home with a widespread drywood infestation.
Understanding the general cost ranges for each treatment type, and more importantly understanding what drives those numbers up or down, helps you evaluate quotes accurately, ask the right questions, and avoid paying for a service that doesn’t match what your home actually needs.
Here’s an honest breakdown of termite treatment costs in Southern California in 2026, organized by method.
Before getting into specific numbers, it helps to understand the variables that determine where any individual job lands within a cost range. No two properties are identical, and the factors below explain why quotes from a professional can vary so significantly from one home to the next even for the same general treatment type.
This is the single biggest cost driver. Localized spot treatment, soil barrier, and whole-structure fumigation have very different labor, material, and equipment requirements. The method chosen determines the base cost range before any other factors are applied.
Larger homes cost more to treat across all methods. Fumigation pricing is typically calculated based on cubic footage, since the amount of gas required scales with the volume of the structure. Soil barrier pricing scales with the linear footage of the foundation perimeter. Spot treatment costs scale with the number of access points and the size of the infested area.
A small, contained infestation is less expensive to treat than one that has spread through multiple areas of the structure. For drywood termites, a colony confined to one section of the attic might be addressed with a targeted spot treatment, while the same species found in the attic, multiple wall sections, and the garage framing would require fumigation. The scope of the infestation directly determines which method is appropriate and therefore what the treatment costs.
Homes with crawl spaces, complex foundation layouts, extensive concrete flatwork, or limited access to certain structural areas may require additional labor for soil treatment drilling, scaffolding, or custom tent work during fumigation. These factors can add to the base treatment cost depending on what the specific property requires.

Before any treatment happens, an inspection needs to confirm what species are present, where the infestation is located, and how far it has spread. The inspection drives every treatment decision that follows, which makes it the most important step in the entire process.
At MEC Termite & Pest Control, termite inspections are free for residential homeowners in Garden Grove and Orange County. This covers a thorough assessment of the full structure, including the foundation, crawl space, attic, interior wall areas, and exterior perimeter.
The one exception to free inspections is real estate and escrow transactions, where a formal WDO (Wood-Destroying Organism) report is required for lenders and escrow companies. These inspections carry a nominal fee due to the specialized legal documentation and liability involved. For standard homeowner inspections, however, there’s no charge.
Spot treatment is the most affordable termite treatment option when the infestation genuinely supports it. For a single, contained drywood termite colony in an accessible section of wood, typical costs in the Southern California market in 2026 range from roughly $300 to $900 depending on the number of access points required and the size of the infested area.
Multiple localized infestations in different areas of the same home, each requiring separate injection points, will increase the total cost proportionally. A technician treating three isolated sections of attic framing is doing three times the labor and material of treating one.
Spot treatment is worth every dollar when it’s matched to a genuinely contained infestation. It’s not worth it when a company recommends it for a widespread infestation because it’s cheaper or easier to sell. A spot treatment applied to one visible frass accumulation point when the colony has already spread through three sections of wall framing won’t resolve the problem. You’ll spend money on treatment and still have active termites.
This is why the inspection matters so much. An honest assessment of whether the infestation is localized enough for spot treatment to work is worth more than the treatment itself.
Soil barrier treatment for subterranean termites is priced primarily based on the linear footage of the foundation perimeter that needs to be treated. In the Southern California market, expect costs in the range of $500 to $1,500 for a typical single-family residence, with larger homes or properties with complex foundation layouts at the higher end of that range or above it.
Homes with extensive concrete flatwork, attached garage slabs, or patios require drilling through the concrete to reach the soil below, which adds labor to the base treatment cost. The drilling is typically billed per linear foot or per hole depending on the company.
Quality soil barrier termiticides applied by a licensed technician at the correct concentration typically provide effective residual protection in the treated soil for five to ten years, depending on the product and local soil conditions. Some companies offer annual monitoring visits to verify the barrier integrity, which may be available as an add-on service.
Fumigation is the most significant investment among termite treatment options, and for good reason. It’s a multi-day process requiring specialized equipment, a full crew, and the expertise to calculate, apply, and safely clear a gas treatment for an entire structure.
In the Southern California market in 2026, fumigation for a standard single-family home typically ranges from $1,500 to $3,500 or more depending on the square footage and cubic footage of the structure. Larger homes, multi-story properties, and homes with complex rooflines or attached structures at the higher end of the range. Some companies price by the linear foot of the tent perimeter rather than by square footage, so it’s worth understanding how a quote is being calculated when comparing providers.
Homeowner preparation costs, including temporary accommodation for two to three nights and any food or consumables that need to be removed or replaced, are separate from the treatment cost. Budget for these as part of your total fumigation expense when comparing it to other treatment options.

Treatment stops the feeding. It doesn’t undo the structural damage that’s already occurred. For many homeowners, especially those dealing with infestations that went undetected for a year or more, the repair cost is as significant as or greater than the treatment cost.
Termite damage repair costs vary enormously depending on what’s been damaged and how extensively. Replacing a single window frame is a minor job. Replacing compromised floor joists across a crawl space, repairing structural studs in multiple wall sections, and refinishing the drywall, texture, and paint in affected rooms is a major restoration project.
MEC’s termite damage remodeling and restoration service covers the full scope of post-treatment repair work, from structural wood replacement through drywall patching, texture matching, and finish painting. Bundling the repair work with the pest control treatment under one company typically provides better coordination and more competitive pricing than hiring a pest company and a separate general contractor independently.
When you receive a treatment quote, the price alone doesn’t tell you whether it’s reasonable. These questions help you evaluate what you’re actually being offered:
MEC Termite & Pest Control has been providing transparent, honest termite treatment pricing to Garden Grove and Orange County homeowners for over 27 years. We don’t recommend treatments based on what’s most profitable to sell. We inspect first, identify what’s actually there, and recommend the method that genuinely fits the infestation.
Our inspections are free for residential homeowners, and our quotes are itemized and explained before any work begins. If a spot treatment will solve your problem, we won’t sell you fumigation. If fumigation is genuinely what you need, we’ll explain exactly why.Call us at 714-951-4015 or contact us online to schedule your free inspection and get an accurate, honest quote for your specific situation. No pressure, no upselling, just a clear answer about what your home needs and what it will cost.
