When you spot termite damage, it can feel like a shock. Homeowners often ask how much it costs to get rid of termites. In my 100+ termite cases, acting fast usually costs less than months of hidden damage.

Termites feed on wood 24/7 and cause more harm each year than fires or floods. According to the National Pest Management Association, termite damage exceeds $5 billion annually. That makes knowing termite treatment cost critical.

Getting rid of termites quickly can save thousands in repairs. This guide shows treatment options, average cost, and why a timely termite inspection matters.

What Determines Termite Treatment Cost? (Factors That Affect Termite Treatment Cost)

Several factors affect termite treatment cost. Each home and infestation is unique. Understanding what drives costs helps you plan a fitting treatment plan.

  • Severity of infestation, from mud tubes to large termite colonies
  • Type of termite causing damage (subterranean termite or drywood termite)
  • Home size and layout, including crawl spaces or slab foundations
  • Soil conditions and moisture issues near the structure
  • Construction type and material, such as wood frame vs. brick

Termite Inspection: Identifying Active Termite Activity Early

A termite inspection pinpoints where termites may be active in your home. Licensed technicians probe key areas to catch infestations early. Regular checks can cut total cost by spotting problems before they spread.

  • Mud tubes lining foundation walls or joists
  • Hollow wood when tapping door and window trim
  • Winged swarmers near lights in spring
  • Live termites in soil or probe holes

Termite Inspection Cost: How Much It Costs to Get a Report

The average termite inspection cost ranges from $75 to $200, depending on home size. Some pest control companies charge by the linear foot of foundation. Getting a detailed report can guide your next steps.

Many providers include a free termite inspection when you request service. Scheduling a professional check ensures you know if termites are active in your home.

Type of Termite: Drywood vs. Subterranean vs. Formosan & Treatment Implications

Knowing your termite species shapes the best treatment plan. In our region, the two common types of termite are the subterranean termite and drywood termite. Formosan termites rarely show up here but pose a rapid threat if they do.

  • Subterranean termite: nests underground, needs soil moisture
  • Drywood termite: lives inside wood above ground
  • Formosan termites: invasive, very aggressive if introduced

According to the University of Georgia, subterranean termites are found in every state except Alaska. Subterranean termite infestations often need soil treatment or baiting, while drywood termite issues may call for fumigation or heat treatment.

Signs of Termites: When to Treat for Termites Based on Mud Tubes, Hollow Wood & Swarmers

Early signs of termite infestation help you treat for termites before serious damage. Spotting problems when they start lowers overall treatment costs and repair bills.

  • Pencil-width mud tubes on foundation or crawl space walls
  • Hollow sounds when tapping wood trim or flooring
  • Discarded wings near window sills during swarm season
  • Soft spots or blistering in wood surfaces

Treatment Options for Termites: Overview of Liquid, Bait & Fumigation

You have three main termite treatments: liquid barriers, bait systems, and whole-structure fumigation. Each method has a different average cost to get rid of termites and a unique way of stopping colonies.

  • Liquid barrier treatments create a chemical trench around your home
  • Termite bait stations lure and eliminate colonies over time
  • Fumigation (tenting) uses gas to clear drywood termite infestations

Liquid Barrier Treatments: Cost Per Linear Foot & Cost to Get Rid of Termites

Liquid treatments involve trenching and drilling around the foundation to apply termiticide. Non-repellent liquids let termites contact the barrier then carry poison back to the colony.

Most liquid treatments cost $3–$16 per linear foot of foundation. For an average home with 200 ft of perimeter, expect $1,000–$3,200 for the initial treatment. Annual renewal fees often run $100–$300.

Termite Bait Systems (Sentricon): Average Cost, Termite Bond & Warranty

Bait systems like Sentricon use stations placed every 10–20 ft around a home. Termites feed on bait, carry slow-acting poison to the colony, and cause collapse over months.

Initial baiting costs range $1,500–$3,000, often $8–$12 per linear foot. Annual maintenance can run $300–$500. Many programs include a termite bond that covers damage repair if termites break through while you stay under contract.

Tent vs No Tent Termite Treatment: When to Choose Fumigation

Whole-structure fumigation (tenting) kills drywood termites inside all wood members. It requires vacating the home for about 2–3 days and does not prevent subterranean termite reinfestation unless you also apply a barrier treatment.

Choose tenting when:

  • Drywood termite activity is widespread inside walls
  • Structures have multiple hidden galleries you can’t reach
  • You want quick, one-time knockdown of interior termites

Tent Termite Treatment Cost: Cost By Severity of Infestation & Structure Size

Fumigation costs based on home size, typically $1–$4 per square foot. A 1,200 sq ft house may cost $1,200–$2,500, while a 2,500 sq ft home can run $2,200–$3,800. Severe infestations or complex rooflines may push costs higher.

Even after tenting, you’ll need a soil treatment or bait system to guard against subterranean termite reinfestation.

DIY Termite Treatments: Risks, DIY Termite Products & When to DIY

Over-the-counter termite baits and sprays exist, but they often fail to reach full colony size or seal all entry points. Improper DIY termite work can leave gaps in a barrier and let termites thrive.

Professionals use calibrated injection tools, EPA approved termiticides, and follow safety standards you can’t replicate with consumer products.

Termite Treatment Cost by Severity: From Spot Treatments to Full Structure

Treatment costs rise with infestation size:

  • Spot treatment for localized activity: $200–$600
  • Barrier treatment for moderate infestations: $1,000–$3,000
  • Full structure treatment (liquid + bait or tenting): $2,500–$5,000+

The severity of damage to framing, multiple termite colonies, and the need for drilling under slabs can push costs higher.

Average Cost of Termite Treatment vs. Cost of Untreated Termite Infestation

The national average for termite treatment is about $1,500. By comparison, the average repair bill for termite damage is $1,800, often rising to $5,000–$10,000 if left unchecked. One homeowner faced over $15,000 in repairs versus a $1,500 preventive plan.

Investing in a termite inspection and treatment can cost less than repairing termite damage later. In fact, research shows termite prevention being cheaper than repairs.

Comparing Treatment Costs: Liquid vs Bait vs Tent vs No Tent Termite Treatments

Treatment options vary in price, speed, and warranty:

  • Liquid barrier: $3–$16/linear ft, quick protection, no damage warranty
  • Termite bait: $8–$12/linear ft, colony elimination, includes damage repair
  • Fumigation: $1–$4/sq ft, one-time purge, no residual barrier
  • Combo plans: Moderate cost, tailored coverage, extended warranties

Preventive Termite Plans & Warranties: Termite Bond, Termite Contract & Programs

Preventive plans and termite bonds can help keep your home protected year-round. Many programs include:

  • Annual termite inspection by registered technicians
  • Unlimited callbacks for retreatment if termites return
  • No long-term contracts—cancel anytime with notice
  • Coverage for initial treatment materials and labor

Our SeasonGuard+ bundle even adds pest and rodent control under one monthly bill.

How to Choose a Termite Control Company: Termite Exterminator Selection Tips

Pick a termite control company based on these criteria:

  • Licensed technicians and clear treatment plans
  • 5-star reviews and referrals from neighbors
  • Transparent pricing and a termite bond option
  • Use of products we’d trust in our own home (EPA approved)

Check local experts like Northern Virginia Termite Control or Alexandria Termite Control.

Termite Conducive Conditions: Impact on Treatment Cost

Certain conditions can raise termite treatment cost and risk:

  • Earth-to-wood contact on decks or siding
  • Mulch piled against the foundation
  • Stumps or firewood stored near the house
  • Poor drainage or HVAC units trapping moisture
  • Inaccessible crawl spaces filled with stored items

Addressing these issues can lower termite activity and cut treatment needs.

Repairing Termite Damage: Cost of Treatment vs. Cost of Repairing Termite Damage

Repairing termite damage can include:

  • Replacing hollow support beams or joists
  • Fixing subfloor and wall studs
  • Cosmetic work like drywall, trim, and paint
  • Potential temporary housing if major work is needed

Each repair adds to the total cost, making early termite removal far more cost-effective.

Internal Research & Expert Recommendations: Sentricon vs. Liquid Treatments

In my experience, proactive bait systems like Sentricon often cost less and cause less stress when caught early. Severe subterranean termite infestations sometimes need targeted liquid treatment with products like Premise® or Termidor® for a faster cure.

Our internal research team vetted every product we use. Each is EPA approved and one we’d use in our own homes.
