How Much Does Termite Treatment Cost? 2026 Proven Guide

The Real Cost of Termite Treatment in 2024

I've crawled through more damp, spider-filled crawlspaces than I care to admit. In my 12 years assessing property damage and coordinating home repairs, termite damage is always the most expensive surprise. Homeowners usually call me after finding a mud tube on their foundation or noticing hollow-sounding baseboards. The first question is always about the price.

Figuring out how much does termite treatment cost isn't straightforward. It depends entirely on the species, the infestation size, and the method your exterminator chooses. I'll break down the exact numbers I see on invoices every week. Termites don't sleep. They eat constantly. If you ignore the small pile of frass near your baseboards, you'll end up paying thousands in structural repairs down the line.

Average Termite Treatment Costs

The national average for a standard termite treatment sits right around $565. However, that number can be misleading. A minor localized spot treatment might only cost $230, while a full-house fumigation for drywood termites can easily exceed $2,500. Here is a breakdown of what you can expect to pay based on the severity and type of service.

Treatment Type	Average Cost	Cost Per Unit
Termite Inspection	$50 - $150	Flat fee
Liquid Soil Treatment	$400 - $1,500	$3 - $16 per linear foot
Bait Station System	$1,200 - $3,000	$5 - $12 per linear foot
Fumigation (Tenting)	$1,200 - $2,500+	$10 - $20 per linear foot
Wood Treatment	$300 - $800	$3 - $5 per square foot

Cost Breakdown by Treatment Type

Exterminators don't just guess a price. They measure your home's perimeter, check the foundation type, and identify the specific termite species. Let's look at the exact methods they use and what you'll actually pay for each one.

Liquid Soil Treatments

This is the most common defense against subterranean termites. The technician digs a 6-inch wide by 6-inch deep trench around your entire foundation. They mix a non-repellent termiticide, usually Termidor SC (fipronil 9.1%), at a ratio of 0.8 fluid ounces per gallon of water. The standard application rate is 4 gallons of mixed solution per 10 linear feet of trench.

I always recommend Termidor SC because of the transfer effect. Termites don't know it's there. They walk through the treated soil, pick up the chemical on their bodies, and carry it back to the colony. The entire colony dies within 60 to 90 days. For an average 1,500-square-foot home with 160 linear feet of foundation, expect to pay between $600 and $1,200. This isn't the cheapest option, but it's the most reliable long-term barrier.

Bait Station Systems

If you have a well, a pond, or a concrete slab that prevents trenching, bait stations are your best bet. The Sentricon Always Active system is the industry gold standard here. Technicians install plastic stations every 10 feet around the perimeter of your house. Inside each station is a Recruit HD bait matrix containing noviflumuron, an insect growth regulator.

Worker termites find the bait, eat it, and feed it to the queen. The queen can't molt, and the colony collapses. Installation for a standard home runs $1,500 to $2,500. You'll also pay an annual monitoring fee of $150 to $300. I'll be honest, this method takes longer to work than liquid treatments. It can take up to six months to eliminate a massive colony.

Fumigation and Tenting

Drywood termites don't live in the soil. They live entirely inside the wood framing of your house. When an infestation is widespread, spot treatments won't cut it. The exterminator will cover your entire house in a massive vinyl tent and pump in Vikane gas (sulfuryl fluoride). The gas penetrates every piece of timber, killing every termite and egg inside.

Tenting is expensive and highly disruptive. You must vacate the home for 24 to 72 hours. You also need to bag all food, medicines, and remove your pets and houseplants. For a 2,000-square-foot home, fumigation costs between $1,800 and $3,000. I'll be honest, tenting your house is a massive headache. It also leaves zero residual protection, meaning a new swarm can fly in the very next day.

Wood Treatments

Borate-based products like Bora-Care or Tim-bor Professional are fantastic for preventative treatments or localized drywood termite issues. These products use disodium octaborate tetrahydrate to poison the wood itself. Technicians spray it directly onto bare, unpainted wood in attics, crawlspaces, and basements.

The wood absorbs the borate salts. Any termite that tries to eat that wood will ingest a lethal dose. This treatment costs $3 to $5 per square foot. It's highly effective for new construction or during a major renovation when the drywall is stripped away. It won't work on painted or sealed wood because the liquid can't penetrate the finish.

Real-World Scenarios and What I Recommend

Pricing sheets only tell half the story. Let's look at how these costs play out in real life when you're actually dealing with an infestation.

Scenario 1: The Home Inspection Surprise

If you're buying a 1980s ranch home and the inspector finds active subterranean mud tubes on the slab, you need a liquid treatment. The seller should ideally pay for this. I recommend a full perimeter trench using Termidor SC. It will cost around $900 for an average-sized ranch. Don't let the seller just spray a cheap repellent inside the walls. That just pushes the termites to a different part of the foundation.

Scenario 2: The Attic Infestation

When your landlord inspects next week and you spot drywood termite kick-out holes in the attic rafters, don't panic. If the damage is limited to one small section, a localized wood treatment with Bora-Care will cost about $300 to $500. The exterminator will drill small holes into the infested beams and inject the borate solution under pressure. It's a quick fix that saves you from tenting the whole house.

Scenario 3: The Deck Swarmers

After hosting a dinner party on your wooden deck, you notice swarmers flying out of the support posts. Subterranean termites love the moisture where wood meets soil. In this case, I recommend installing an Advance Termite Bait System around the deck footings and the adjacent house perimeter. It will cost about $1,200. You'll also need to replace the rotted support posts, which is a separate carpentry bill.

Factors That Change Your Final Bill

Your neighbor might have paid $600 for their treatment, but your quote could be $1,500. Several physical variables dictate the final price.

• Foundation Type: Slab foundations require the technician to drill through the concrete every 12 inches and inject termiticide underneath. This rodding process adds significant labor time. Crawlspaces are cheaper to treat because the soil is exposed.
• House Size and Perimeter: Exterminators charge by the linear foot of the foundation, not the square footage of the living space. A sprawling single-story home costs much more to treat than a compact two-story house with the same square footage.
• Termite Species: Subterranean termites require soil treatments. Drywood termites require wood injections or fumigation. Formosan termites are highly aggressive and often require a combination of both liquid and bait systems, driving the price up by 30% to 50%.
• Obstacles and Landscaping: If you have concrete patios, AC units, or dense shrubbery hugging the foundation, the technician has to work around them. Removing obstacles or trenching through decorative concrete pavers will add $200 to $500 to the labor cost.

DIY vs Professional Treatment

I get asked all the time if you can just buy the chemicals yourself. You can. Products like Taurus SC (the generic equivalent to Termidor) are available to homeowners in many states. A 20-ounce bottle costs about $65 and treats 60 linear feet. If you have a small shed or a detached garage, DIY makes financial sense.

However, treating a main residence is a different story. Trenching around a slab foundation will wreck your back if you do it yourself. You also need a specialized sub-slab injector to treat under concrete patios and driveways. Most homeowners just spray the surface and wonder why the termites keep coming back. For your primary residence, hire a licensed pro. They carry the commercial-grade equipment and offer a warranty that covers structural damage if the termites return.

Frequently Asked Questions

How long does a termite treatment last?

Liquid soil treatments like Termidor SC typically last 5 to 10 years in the soil. Bait stations require annual monitoring and last as long as you maintain the service contract. Fumigation kills existing colonies but offers zero residual protection, meaning termites can return the very next day.

Is termite treatment covered by homeowners insurance?

Standard homeowners insurance policies almost never cover termite damage or treatment costs. Insurers classify termite infestations as a preventable home maintenance issue. You will have to pay out of pocket unless the damage causes a sudden, covered collapse of the structure.

Can I treat my house for termites myself?

You can apply DIY liquid treatments using products like Taurus SC, but it requires digging a 6-inch trench around your entire foundation. Most homeowners lack the specialized rodding equipment needed to inject termiticide under concrete slabs. I highly recommend hiring a licensed professional for structural infestations.

How do I know if the termite treatment worked?

You should see a complete cessation of termite activity within 60 to 90 days after a professional liquid or bait treatment. The exterminator will schedule a follow-up inspection to check for fresh mud tubes or new frass piles. If you still see live swarmers after three months, the company must re-treat the area for free.
