Drywood termite fumigation typically costs $1,200-$8,000 for a U.S. home, with many average-sized houses priced around $2,500-$5,000. The final quote depends mainly on the structure’s size, regional labor rates, tenting access, infestation scope, and required preparation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Whole-home fumigation | $1,200 | $3,500 | $8,000 | Often priced by treated floor area and building volume |
| Price per square foot | $1.00 | $2.25 | $4.00 | Access, location, and house shape affect the rate |
| Small detached structure | $500 | $1,200 | $2,500 | Garage or outbuilding pricing varies by size and access |
| Preparation and related charges | $0 | $250 | $800 | May include food preparation, special access, or added work |
What drywood termite fumigation costs for a typical home
Whole-structure fumigation generally runs about $1-$4 per square foot of treated floor area. A 1,000-square-foot home may cost $1,200-$3,500, while a 2,000-square-foot home often falls around $2,500-$6,000. Large, complex, or difficult-to-tent properties can exceed those ranges.
A practical planning estimate is $2,500-$5,000 for a typical house, before any repairs to termite-damaged wood. That estimate assumes a licensed pest-control company, standard tent access, a moderate infestation, and no major structural repairs. The square-foot figure is a comparison tool rather than a guaranteed quote: companies may also account for building volume, roofline, attached structures, and fumigant requirements.
Prices are usually quoted for treating the structure, not repairing damage. Replacing fascia, framing, trim, or flooring after treatment can add hundreds or thousands of dollars, depending on the amount and location of damaged wood. Ask whether the estimate includes a post-treatment inspection or warranty, and have repairs itemized separately.
Assumptions: U.S. home with ordinary access, standard tenting, and no major carpentry work.
How tenting, fumigant, and crew labor shape the quote
A fumigation estimate combines site preparation, tent installation, gas treatment, monitoring, and tent removal. Companies may not disclose each internal expense, but an itemized quote should show what is included and identify charges that could change after inspection.
| Quote component | Typical range | What it covers | Pricing note |
|---|---|---|---|
| Tenting and labor | $600-$2,000 | Cover placement, sealing, and removal | Roof height and access can raise labor time |
| Fumigant and monitoring | $400-$1,500 | Gas charge, exposure, and safety checks | Building volume and treatment plan matter |
| Inspection and setup | $100-$500 | Assessment, scheduling, and site planning | May be included in the total quote |
| Food and item preparation | $0-$500 | Preparation supplies or specialized handling | Customer preparation can reduce paid services |
| Delivery, disposal, and overhead | $100-$800 | Transport, equipment, insurance, and business costs | Often rolled into the contract price |
Labor rates vary by market, but pest-control or fumigation labor may equate to roughly $75-$150 per worker-hour when considered as a quote component. Customers generally pay a project price rather than an hourly bill. A rough labor calculation is ; it is useful for comparing explanations, not for predicting the final contract amount.
Confirm that the quoted price covers the complete treatment cycle, including monitoring and tent removal. A low base price may exclude preparation services, difficult access, or treatment of a detached garage. Ask for the total due, exclusions, and any conditions that could trigger an added charge.
Why square footage, roof shape, and access change the price
Floor area is an important starting point, but fumigation is planned around the entire enclosed structure. A two-story house with a complicated roof can require more tenting and labor than a single-story home with the same square footage. Attached garages, enclosed porches, and additions may also need to be included in the treatment plan.
Size can push a project into a higher budget tier. A home under 1,000 square feet may be near $1,200-$3,500, while a 2,500- to 3,500-square-foot home may run $4,000-$8,000 or more in a higher-cost market. The estimate should state which structures and enclosed areas are included rather than relying on the home’s listing square footage alone.
Roof pitch, narrow side yards, landscaping, and neighboring buildings can limit how crews place and secure a tent. A steep or obstructed roof, for example, may add $200-$1,000 when it requires extra labor or equipment. Detached garages and outbuildings can add roughly $300-$1,500 each, depending on size and whether they can be treated with the house.
Infestation scope also matters. Fumigation treats the enclosed structure, so the price is not necessarily proportional to the number of visible termite holes. If activity is limited to a small, accessible wood component, a professional may quote a localized treatment instead; widespread activity or inaccessible infestation may make whole-structure fumigation more suitable.
Ask the contractor to measure and price the actual treatment envelope, not just the home’s advertised living area. Provide details about additions, attached spaces, roof access, and detached buildings before comparing estimates.
How many days the crew needs and when residents can return
Most tent fumigation projects require residents to leave for about two to three days, although scheduling and site conditions can extend the disruption. The work typically includes tent installation, fumigant exposure, ventilation, and air-safety testing before the company authorizes re-entry. The pest-control contractor sets the required schedule and confirms when the home is safe to occupy.
The crew may be on site for several hours during tenting and again during removal, but treatment time is not the same as hands-on labor time. A compact, accessible home may be tented and sealed in a few hours; a large or complex property can take longer. Do not plan a return based on a general estimate or the time a tent comes down.
Some companies charge a rescheduling or cancellation fee, commonly $100-$500 when a crew has been dispatched or a treatment slot has been reserved. Weather, access problems, or incomplete preparation can disrupt the schedule. Ask about these conditions in writing, along with the company’s instructions for food, medicines, plants, pets, and re-entry.
Build lodging, meals, and missed work into the household budget even when they are not part of the fumigation invoice. The cost depends on the household and location, so request the expected start and release times before booking.
How California, Florida, and other markets compare
Regional labor costs, licensing requirements, demand, and travel distance can shift a quote substantially. As a broad comparison, prices in high-cost coastal metro areas may be 15%-35% above the national midpoint. Rural markets may be 5%-20% below it, but a long service trip or limited contractor availability can offset that difference.
| Market type | Typical 1,500-square-foot quote | Compared with national midpoint | Common pricing pressure |
|---|---|---|---|
| High-cost coastal metro | $3,500-$6,500 | 15%-35% higher | Labor, access, and dense housing |
| Mid-cost metro or suburb | $2,500-$4,800 | Near the midpoint | Roof complexity and local demand |
| Rural or lower-cost market | $2,000-$4,200 | 5%-20% lower in some areas | Travel fees and fewer providers |
California and parts of Florida have established markets for drywood termite control, but prices still differ between cities and even between properties in the same area. A coastal address, tight lot, or multi-story design may cost more than a similarly sized home with clear access. These regional bands are planning ranges, not state price guarantees.
Compare at least two local, licensed providers using the same scope and treatment assumptions. Check that each quote includes the same buildings, preparation instructions, monitoring, and re-entry clearance so that a lower regional price is a fair comparison.
What three realistic fumigation quotes may include
These examples illustrate how size and access can change a total. They assume professional whole-structure treatment and exclude repairs to damaged wood. Actual quotes depend on inspection and local rates.
| Property and scope | Estimated labor | Rate basis | Illustrative total |
|---|---|---|---|
| 900-square-foot single-story home, clear access | 8-12 crew-hours | $1.50-$2.60 per sq ft | $1,350-$2,340 |
| 1,600-square-foot two-story home, moderate roof complexity | 14-20 crew-hours | $1.70-$3.00 per sq ft | $2,720-$4,800 |
| 2,800-square-foot home with attached garage and restricted side access | 22-32 crew-hours | $2.00-$3.60 per sq ft | $5,600-$10,080 |
In the first example, the compact footprint and clear access keep tenting and setup relatively straightforward. In the second, added roof work and larger building volume raise the labor and material needs. The third combines greater size with a garage and restricted access; the top end may apply in an expensive metro or when the contractor must use additional crew or equipment.
Use examples to test whether a quote is plausible, not to substitute for a site inspection. If a proposal is far below or above a comparable range, ask which scope, access, treatment, or included service accounts for the difference.
Fumigation versus localized treatment for drywood termites
Localized options can cost less when evidence points to a small, reachable infestation. Spot treatment may run about $200-$800 per treated area, while localized heat, microwave, or other specialized treatments can cost roughly $500-$2,500 depending on the method and size of the affected wood. These approaches do not automatically cover hidden colonies elsewhere in a structure.
Whole-home fumigation often makes more sense when activity is widespread, multiple areas are affected, or termites are suspected in inaccessible framing. It treats the enclosed structure but generally does not leave a lasting protective barrier against future infestation. New termite activity can occur later, and damage repairs remain a separate expense.
Ask the inspector to identify the evidence, explain what each treatment can reach, and describe the limitations of a spot treatment. If the scope is uncertain, compare a fumigation estimate with a clearly defined localized-treatment quote. A cheaper treatment is not a savings if it leaves known active areas untreated.
Compare the treatment coverage and likelihood of missed colonies, not only the initial invoice. The right price comparison depends on the verified infestation and what the contractor promises to treat.
How to lower a fumigation bill without cutting coverage
Start by controlling scope. Confirm whether a detached shed, garage, or enclosed addition has evidence of termites and whether it must be treated at the same time. Removing an outbuilding from the quote may lower the bill, but only if the inspector agrees that it can safely remain untreated and the customer understands the risk.
Complete customer preparation carefully if the company permits it. Following instructions for bagging or removing food, clearing access, and securing personal items can avoid paid preparation services or a delayed appointment. Do not skip required steps or improvise around fumigation instructions; the contractor’s safety protocol takes priority over a small potential saving.
Compare written bids with matching square footage, buildings, treatment dates, monitoring, and exclusions. Ask whether the inspection or travel charge is credited toward the job, whether preparation supplies are included, and whether payment terms change the total. Bundling a detached structure with the home may reduce a separate mobilization charge, though not every property can be treated together.
Choose the least expensive quote only when it provides the same coverage, safety steps, and re-entry clearance. Avoid paying for optional upgrades unless the contractor explains a specific benefit, and keep wood repairs separate so you can compare those bids independently.
