What termites cost to remove usually lands between $260 and $1,000, according to HomeAdvisor’s 2025 cost survey, and the total has less to do with how many insects are in the wall than with the shape of the foundation under it.
Termites are the rare household pest that converts a maintenance habit into a budget line, because a homeowners policy almost never covers the damage they leave.
A removal quote prices a measurement, not an animal. It covers the length of the foundation perimeter, the depth of soil treated, and the amount of concrete standing in the way, which is how two companies can price the same home hundreds of dollars apart and both be right.
Why Termites Cost to Remove More on Some Houses
Termites cost to remove tracks the length of the foundation perimeter, the depth of soil treated, and how much concrete has to be drilled. Interior square footage barely registers in the calculation.
Pricing by perimeter surprises people who think in floor area. A 1,200-square-foot one-story ranch and a 2,400-square-foot two-story colonial can share a footprint, which means the same number of linear feet to trench. The colonial costs twice as much to heat and the same to protect.
Shape moves the number further than size does. An L-shaped plan with a garage bump-out, a screened porch on a slab, and an interior load-bearing pier line can push the perimeter well past what the square footage suggests, because every jog adds corners, and corners are the slowest soil to reach.
How a Quote Turns Perimeter Feet Into Gallons
Termiticide labels, not companies, set the volume: 4 gallons of dilution per 10 linear feet of trench, for every foot of depth. A 176-foot perimeter treated four feet deep needs about 70 gallons of finished solution.
The Florida Department of Agriculture and Consumer Services states that total solution volume is identical across all termiticide labels. Only the concentration of active ingredient varies by product. A bid that comes in far under its competitors is therefore treating less soil, or using less product than the label allows.
That second possibility has a regulatory history. EPA’s 1994 termiticide labeling notice ended the practice of applying below-label rates, because under-application produced failed barriers, expensive retreatments, and property damage.
Run the arithmetic the way a training workbook does. Mississippi State University Extension’s termite math example takes 280 linear feet, multiplies by 0.4 gallons per foot of depth, and lands at 112 gallons. A Virginia pretreat brochure works 176 linear feet the same way and gets 70.4 gallons.
Depth supplies much of the five-fold spread in per-foot pricing. A label directs the applicator to treat from grade to the top of the footing, and where the footing sits deeper than four feet, to reach a minimum of four feet. Treatment never goes below the footing, which is also the rule that stops a crew from charging you for soil that should never be touched.
Soil type changes the volume again. Clay takes water slowly and may require a higher concentration rather than more liquid. Coarse or gravel fill under a slab calls for 1.5 gallons per 10 square feet where sand fill takes 1 gallon. Hollow block foundation voids take 2 gallons per 10 linear feet, and expansion joints and cracks take 4 gallons per 10 linear feet on top of the perimeter trench.
Published method bands stay wide for the same reason. HomeGuide’s 2026 cost guide quotes liquid soil barriers at $3 to $16 per linear foot of perimeter, bait systems at $7 to $12 per linear foot, and fumigation at $1 to $4 per square foot. On a 200-foot perimeter, that band runs from about $600 to $3,200 for a liquid job before any repair is priced in.
Foundation Type Decides How Much Drilling the Work Needs
A crawl space is usually the cheaper foundation to treat, because the soil is reachable. A slab requires boring through concrete at intervals of 12 inches or less along the perimeter, treating the voids and expansion joints, then plugging every hole.
The trench carries dimensions of its own: at least 6 inches deep, or down to the bottom of the footing where that is shallower, and no wider than 6 inches. On sloping ground it has to be stepped so the emulsion does not run off before it soaks in.
Rod hole spacing is capped at 12 inches for the same reason a fence needs posts, since the point is a continuous barrier instead of a dotted line. Pier lines, plumbing penetrations, and block voids each take a separate application at their own rate, and a home with a well or cistern inside the foundation footprint needs treated backfill, a slower method that shows up as labor.
Labels forbid treating frozen or saturated soil, and they require anti-backflow equipment that keeps termiticide out of wells and surface water. Those two sentences are why a bid scheduled for the week after heavy rain sometimes gets pushed, with no change in price attached to the delay.
Access shows up as labor hours.
A three-foot hatch under a deck, ductwork choking the center run, or a vapor barrier stapled down across the soil all add hours to the same visit.
What Has to Happen Before Treatment Day
Clear the soil line before the crew arrives. Move firewood, stumps, and stacked lumber away from the foundation, cut plants back off the siding, repair the downspout dumping water against the wall, and open a path into the crawl space.
Mulch beds, an old stump, and a woodpile against the wall hold moisture and create the temperature gradient termites follow. Removing them is not prevention marketing. It decides whether one crew can reach the entire perimeter in a single visit.
Indoors, the prep is furniture and flooring. Technicians drill through a garage slab or porch floor at fixed intervals, and a rug, a treadmill, or a shelf of paint cans sitting over the drilling line adds handling time to the visit.
Fumigation asks for more. Residents and pets leave for the duration of the aeration sequence, food and medications are either removed or sealed according to the company’s written instructions, and nobody goes back in until the certified applicator confirms the structure is clear.
Flying termites at an interior light, mud tubes climbing a foundation wall, or frass pellets under a window sill are the signals that move a home from prevention planning into active treatment.
None of that preparation substitutes for treatment. Clearing debris changes the conditions termites prefer; it does not remove a colony already feeding on a sill plate.
Where the Cheap Quote Hides Its Extra Lines
Scope answers what termites cost to remove; the headline figure usually does not. The lowest bid is often the shortest scope, and wood repair, a post-tenting soil barrier, annual re-inspection, and repair-backed warranties tend to arrive later as separate invoices.
Carpentry is a different trade, and it is where household budgets break. Killing a colony stops new damage. It does not restore a joist, a rim board, or a door frame that has already been hollowed out, and load-bearing lumber needs its own contractor and, often, its own engineering opinion. A tent job leaves the yard untouched as well, since sulfuryl fluoride kills what lives in wood while subterranean colonies live in soil, so most fumigation proposals are followed by a barrier or bait program that a first-time buyer never budgeted for. Nothing in a pest control contract obligates a company to rebuild what a colony already ate. The National Pest Management Association puts U.S. termite damage at $6.8 billion a year, and that repair share lands on the owner, because a standard policy reads gradual insect damage as a maintenance failure.
Inspection paperwork is not a damage report either. The NPMA-33 form that lenders and the VA accept records visible evidence on the date of the inspection and carries no warranty unless an attachment is noted in Section V. VA and FHA transactions treat the report as valid for 90 days. Nothing in it estimates what the framing will cost to fix.
Warranty language decides the recurring half of the price, and the distinction is formal enough that states regulate it. Florida’s consumer guidance for post-construction termite contracts requires the agreement to state whether it is retreatment-only or retreatment-and-repair and to name the maximum repair amount, because both products can carry similar first-year prices and very different obligations. A retreatment-only contract leaves every repair bill with the owner.
Renewals and lapses close the loop. Annual renewal on a liquid barrier commonly runs a few hundred dollars. Let the contract expire and reinstatement usually requires a fresh inspection and a new initial treatment rather than a back-dated payment. On a bait program, protection ends the day the monitoring stops, because the stations hold the active ingredient.
Who Is Allowed to Do the Work, and What a Homeowner Can Legally Do
Termiticide labels typically restrict use to individuals or firms licensed or registered by the state, and structural fumigants are restricted-use pesticides. The barrier itself sits out of reach for a homeowner, while preparation, drainage, and repair stay with you.
EPA’s guidance on “for use only by” label statements describes an awkward gap. These products can be sold online to anyone, because the agency cannot restrict distribution without classifying a product as restricted-use, yet only state-licensed or registered people may lawfully store or apply them. Buying a jug and having the legal right to apply it are two different things.
States layer their own requirements on top of federal label language. Rhode Island requires a certified applicator physically present during subsurface termiticide application. New York requires direct on-site supervision for sub-slab and void work, and two employees present for certain exterior basement wall or under-slab treatments, with one stationed indoors to watch for intrusion. New Jersey requires occupant notification and evacuation for the duration of application and for 24 hours afterward.
What stays genuinely useful for a homeowner is the perimeter work: drainage correction, soil contact removal, moisture control, and the carpentry that follows treatment. Retail products marketed for swarming termites address a visible surface problem and cannot build a soil barrier. When the immediate question shifts from budgeting to execution, the termites how to get rid of them a realistic guide walks the treatment sequence itself.
Hand the work to a licensed professional, and to a structural contractor as well, when swarmers emerge indoors, when trim sounds hollow under a tap, when a floor has started to sag, or when activity turns up near wiring and gas appliances. Those signals put the problem past pest control and into structural and electrical safety.
Fumigation Costs What It Costs Because of a Safety Sequence
A tent job carries an aeration and clearance sequence: at least 12 hours before re-entry at ordinary residential doses, up to 24 hours at the highest doses or in cold weather, and a room-by-room reading of 1 ppm or less before anyone goes back inside.
EPA tightened residential fumigation labels after at least 11 deaths and two serious injuries in California and Florida since 2002, every one of them in homes that had already been cleared for re-entry. The amended labels took effect in July 2024 and added site-specific fumigation logs, longer aeration periods, and a change in how clearance devices are chosen.
Sulfuryl fluoride has no odor, so chloropicrin is released as a warning agent at least five minutes before the fumigant. Warning signs stay posted at every entrance for the whole process, and only a certified applicator can take them down and declare the building safe.
That sequence is why the crew asks for two or three days instead of an afternoon. The structure has to sit open and be tested room by room, in the zones where people stand, sit, and sleep.
Comparing Two Quotes Without Comparing Prices
Ask both companies for the perimeter length, the treated depth, whether slab drilling and void treatment are included, what the warranty obligates them to do, and the annual fee after year one. Bids that answer those questions differently are not competing bids.
Two proposals become comparable only when each one states what termites cost to remove and what that price leaves out. Require these lines in writing:
- Linear feet of foundation perimeter, and the depth proposed for each run of trench.
- Whether interior piers, expansion joints, and block voids are treated, and whether drilled holes get plugged and patched.
- The termiticide’s EPA registration number and the concentration to be mixed.
- Whether a post-tenting soil treatment is included when the colony is a drywood species.
- Warranty type, any repair cap, and the conditions that void coverage.
- Annual renewal amount, re-inspection frequency, and the charge to reinstate a lapsed contract.
Two numbers that differ by several hundred dollars read differently once the scope lines match up. Where one bid lists 180 linear feet at four feet of depth and the other never mentions depth, the higher price may be the more complete proposal, priced honestly.
Can Termites Ever Be Fully Removed?
For subterranean species, treatment installs a barrier or a monitoring grid rather than clearing every colony from the soil. Fumigation empties wood, not soil, so most tent jobs are paired with a soil program.
A liquid barrier keeps working years after the last renewal payment, since treated soil does not expire with an invoice. A bait program’s protection ends when the monitoring stops, and the value it buys is early detection rather than residual protection in the soil.
A five-year view beats the first invoice. First treatment, renewals, whatever repair the warranty leaves out, and the carpentry that follows all land on the same household budget.
Frequently Asked Questions
Is it expensive to get rid of termites?
Termite removal is usually a mid-hundreds to low-thousands expense while the damage is still hidden. HomeAdvisor’s 2025 cost data puts the typical job near $620, with the middle of the market running from about $263 to $1,032. The expensive version of the same problem is the repair bill that arrives after a colony has been feeding for years.
What do termites cost to remove when the activity is confined to one area?
A localized treatment is the cheapest version of the work, because the full perimeter trench is skipped. Published cost guides put spot treatment in the low hundreds of dollars. The catch is proof, since a single-room infestation still needs an inspection covering the whole structure. A visible patch of damage is often the colony nearest the surface rather than the only one present.
Will homeowners insurance pay for termite treatment?
Standard homeowners policies exclude it. Insurers classify gradual insect damage as a maintenance failure instead of a sudden peril, and most policies name insects and vermin as exclusions. A narrow exception applies when termite damage triggers a covered event, such as chewed wiring starting a fire, and even then the pest damage itself stays excluded.
How much does Terminix charge to get rid of termites?
National pest control brands do not publish price lists. Terminix and its competitors sell programs, either recurring bait monitoring or a one-time soil treatment, and both get priced after a local inspection of the perimeter and foundation type. A written proposal for your own address is the only figure that means anything.
How long does a termite treatment last?
EPA expects soil termiticides to hold for at least five years, and a correctly installed barrier often keeps working longer, which is why renewal payments and residual protection are separate things. Bait monitoring lasts as long as the service continues. Fumigation leaves no residue, so a drywood tent job protects the wood it treated and nothing in the soil.
