Fumigation Cost: 2026 Tenting Prices by Home Size
Last updated: March 1, 2026
Home fumigation costs $4,000 to $8,000 on average, or roughly $4 to $8 per square foot. Fumigation (also called tenting) is a whole-structure treatment that eliminates pests throughout the entire home. It is most commonly used for drywood termites and severe bed bug infestations.
This guide breaks down fumigation costs by home size, pest type, and what to expect during the process. For a broader view of treatment options, see our pest control cost guide.
Average Fumigation Cost in 2026
Fumigation pricing is typically calculated per square foot. The exact rate depends on the pest being treated, your location, and the fumigation company.
| Pricing Method | Average Cost | Typical Range |
|---|---|---|
| Per square foot | $6/sq ft | $4 – $8/sq ft |
| Flat rate (small home) | $3,500 | $2,500 – $4,500 |
| Flat rate (average home) | $5,500 | $4,000 – $7,000 |
| Flat rate (large home) | $8,500 | $6,500 – $12,000+ |
Most fumigation companies provide a flat-rate quote after inspecting the property rather than strictly calculating by square footage. The per-square-foot rate is useful as a rough estimate, but your actual quote will factor in the home's layout, accessibility, and the pest being treated.
Fumigation Cost by Home Size
Larger homes require more fumigant gas, larger tarps, and more labor. The table below shows estimated costs by home square footage.
| Home Size | Estimated Cost |
|---|---|
| 1,000 sq ft | $2,500 – $4,500 |
| 1,500 sq ft | $3,500 – $6,000 |
| 2,000 sq ft | $4,000 – $8,000 |
| 2,500 sq ft | $5,000 – $10,000 |
| 3,000 sq ft | $6,000 – $12,000 |
| 4,000+ sq ft | $8,000 – $16,000+ |
Fumigation Cost by Pest Type
While the fumigation process is similar regardless of the pest, the required concentration and exposure time vary, which can affect pricing.
| Pest Type | Typical Fumigation Cost | Notes |
|---|---|---|
| Drywood termites | $4,000 – $8,000 | Most common reason for fumigation |
| Bed bugs | $4,000 – $8,000 | Used for severe, whole-home infestations |
| Powderpost beetles | $3,500 – $7,000 | Wood-boring beetle treatment |
| Stored product pests | $3,000 – $5,000 | Grain beetles, pantry moths |
Drywood termites are by far the most common reason for residential fumigation. In states like Florida, California, and Hawaii where drywood termites are prevalent, fumigation is a routine treatment. For subterranean termites, liquid barrier or baiting treatments are used instead of fumigation.
What Is Included in Fumigation Cost?
A standard fumigation quote typically includes the following:
- Pre-inspection: a thorough assessment of the home to determine the pest, extent of infestation, and treatment plan
- Tarp setup and removal: the labor and materials to seal your home with fumigation tarps
- Fumigant gas: the chemical treatment itself (typically sulfuryl fluoride / Vikane)
- Monitoring: gas concentration monitoring throughout the treatment period
- Aeration: ventilating the home and testing air quality to ensure it is safe for re-entry
- Clearance certificate: written confirmation that the home is safe to occupy
What is typically not included: temporary housing costs during fumigation (2 to 3 nights at a hotel), food and medicine removal/replacement, and landscaping repair if plants near the house are affected.
Fumigation vs. Alternative Treatments
Fumigation is the most expensive pest treatment option. Understanding when it is necessary versus when alternatives will work can save you thousands.
| Treatment | Cost | When to Use |
|---|---|---|
| Fumigation (tenting) | $4,000 – $8,000 | Severe drywood termite infestations, whole-home bed bug infestations |
| Heat treatment | $2,000 – $4,500 | Bed bugs (1-day treatment), localized termite infestations |
| Spot / localized chemical | $250 – $1,000 | Small, contained infestations in accessible areas |
| Liquid barrier (termites) | $1,200 – $3,500 | Subterranean termites (fumigation not appropriate) |
| Baiting system (termites) | $1,500 – $3,500 | Subterranean termites with ongoing monitoring |
Fumigation is generally recommended only when the infestation is too widespread for localized treatment, or when the pests are inaccessible inside walls and structural wood. If your pest control company recommends fumigation, ask whether spot treatment or heat treatment is a viable alternative for your situation.
What Factors Affect Fumigation Cost?
Home size
Square footage is the primary cost driver. More space requires more gas, larger tarps, and more labor. Multi-story homes cost more than single-story homes of the same square footage due to the additional height of tenting required.
Pest type and severity
Different pests require different gas concentrations and exposure times. Severe infestations may require higher concentrations or longer treatment periods, which increases cost.
Location
Fumigation costs more in regions where it is less common. In states with high drywood termite pressure (Florida, California, Hawaii), competitive pricing keeps rates lower. In areas where fumigation is rare, fewer companies offer the service, which can drive prices up.
Roof type and accessibility
Homes with complex rooflines, tile roofs, or multiple levels are harder to tent. Tile roofs require special clamps and precautions to prevent damage. Homes with attached structures, gazebos, or extensive landscaping close to the foundation can also increase setup costs.
Time of year
Fumigation demand peaks during warmer months when termite swarms are most active. Scheduling during the off-season (late fall or winter) may result in lower pricing in some markets.
What to Expect During Fumigation
The fumigation process follows a standard timeline. Knowing what to expect helps you prepare and plan.
- Pre-treatment preparation (1 to 2 days before): Remove all food, medicine, pets, and plants. Double-bag consumables in special bags provided by the company. Arrange temporary housing.
- Tenting (day 1 morning): The crew covers your home with sealed tarps and posts warning signs. Gas is introduced.
- Treatment period (24 to 48 hours): The fumigant circulates throughout the structure, penetrating walls, attics, and wood framing.
- Aeration (day 2 or 3): Tarps are removed and the home is ventilated with fans. Air quality is monitored.
- Clearance (same day as aeration): Once gas levels reach safe thresholds, you receive a clearance certificate and can return home.
Plan for 2 to 3 nights away from home. The total timeline from tenting to re-entry is typically 48 to 72 hours.
How to Save on Fumigation
- Get multiple quotes. Fumigation is a high-cost service with significant price variation. Compare at least three estimates.
- Ask about spot treatment first. If the infestation is localized, a spot treatment ($250 to $1,000) may resolve the issue without full fumigation.
- Schedule in the off-season. Fall and winter may offer lower rates when demand is lower.
- Bundle with other services. Some companies offer discounts if you combine fumigation with an ongoing pest prevention plan.
- Check for financing options. Many fumigation companies offer payment plans to spread the cost over 6 to 12 months.
- Negotiate warranty terms. Ensure your quote includes a warranty period (typically 1 to 2 years) that covers reinfestation at no additional cost.
