The short version
Termite treatment typically costs $1,200 to $3,000 for liquid or bait systems, with fumigation ranging $500–$8,000. Most homeowners insurance does not cover damage, so early detection and professional treatment are critical.
- Termites cause $5 billion in property damage annually in the US.
- Spring (March–May) is peak swarm season; year-round risk in the Gulf Coast and Southeast.
- Professional treatment averages $1,200–$3,000; fumigation can reach $8,000.
- Most homeowner policies exclude termite damage.
For homeowners, real estate agents, property managers, and landlords who need clear, accurate information about termite control. If you're buying or selling a home, managing rental properties, or suspect an infestation, understanding treatment costs, prevention, and regulations (like WDO/WDI reports) will help you make informed decisions.
What to look for
Because termites often work unseen, damage may only be discovered during renovations or real estate inspections. In many states, a termite inspection (Wood Destroying Organism / Wood Destroying Insect report) is required for real estate transactions. Waiting to address an infestation can lead to costly repairs — the average cost to repair termite damage is several thousand dollars, and in severe cases, can exceed $10,000. Termites are wood-destroying insects that can compromise the structural integrity of a building. Subterranean termites, the most common type in the US, live in underground colonies and build mud tubes to reach above-ground wood. The Formosan subterranean termite, found primarily along the Gulf Coast, is especially aggressive and can cause severe damage in a short time.
- 1Mud tubes on foundation walls, floor joists, or crawl spaces (subterranean termites).
- 2Hollow-sounding wood when tapped — a sign of internal damage.
- 3Discarded wings near windows, doors, or light sources (swarmers).
- 4Frass: small, pellet-like droppings from drywood termites near wood surfaces.
- 5Blistered or buckling wood floors, ceilings, or walls.
- 6Tight-fitting doors or windows due to wood swelling from moisture or damage.
- 7Visible wood damage with a honeycomb pattern inside.
Why it’s worth acting soon
- Structural weakening: Load-bearing beams and joists can be compromised, leading to sagging floors or roof collapse.
- Increased repair costs: Delaying treatment can multiply repair expenses by 10x or more.
- Spread to adjacent properties: In multi-unit buildings or neighborhoods, untreated colonies can expand.
- Health hazards: Though rare, termites can trigger allergies or asthma from droppings and mold growth.

Treatment options and typical costs
Liquid Soil Treatment
$1,200–$2,500
A chemical barrier is applied to the soil around the foundation to kill and repel termites. Commonly uses termiticides like fipronil or imidacloprid.
- Time
- 5–10 years with proper application
- Best for
- Subterranean termite infestations; new construction or existing homes with accessible foundation.
Bait Station System
$1,500–$3,000
In-ground stations containing a slow-acting bait are placed around the property. Termites carry the bait back to the colony, eliminating it over weeks to months.
- Time
- Ongoing monitoring required; bait replenished as needed
- Best for
- Property owners seeking a low-chemical, ongoing protection plan; large or multiple colonies.
Fumigation (Tenting)
$2,000–$8,000
The entire structure is sealed and filled with a gas (typically sulfuryl fluoride) to eliminate all termites inside, including drywood termites.
- Time
- 24–72 hours of treatment; occupants must vacate for 2–3 days
- Best for
- Severe, widespread drywood termite infestations; whole-structure treatment.
Wood Treatment / Spot Treatment
$300–$1,000
Direct application of liquid or foam termiticide to infested wood or void areas. Often used as a supplementary or localized treatment.
- Time
- Variable; may need reapplication
- Best for
- Small, localized infestations; drywood termites in accessible areas.

Termite treatment costs vary widely based on the method, property size, and region. For a typical single-family home, liquid soil treatments range from $1,200 to $2,500, while bait systems run $1,500–$3,000. Fumigation for drywood termites can cost $2,000–$8,000 for a whole-house tent. These prices usually include a one-year warranty and can be renewed annually for a fee (often $200–$500). Be wary of unusually low bids — they may indicate inadequate treatment or lack of warranty. Factors that influence pricing include the severity of the infestation, accessibility of the affected areas, and your region's termite pressure. For example, treatment in the Southeast or Gulf Coast may be more expensive due to higher termite activity and the presence of Formosan termites.
Regional Termite Risks Across the US.
Termite risk is not uniform across the country. The highest risk zone is the Gulf Coast and Southeast, where warm, humid conditions allow subterranean and Formosan termites to thrive year-round. In these areas, swarm season begins as early as February, and homes require vigilant monitoring. The Formosan termite, in particular, is known for its aggressive colony size — up to several million — and ability to infest structures quickly. In the Midwest and Northeast, subterranean termites are common but less aggressive. Swarm season runs from March to May. Homes with basements or crawl spaces are at higher risk. In the West, drywood termites are prevalent in coastal California and the Southwest, requiring different treatment approaches like fumigation or spot treatments. Understanding your local termite species and activity patterns helps in choosing the right prevention and treatment strategy. A local pest control expert can provide tailored advice.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.Real Estate Transactions and Termite Inspections.
In many states, a termite inspection (Wood Destroying Organism or Wood Destroying Insect report) is required as part of a real estate transaction. Lenders often mandate a clear report before approving a mortgage. The inspection looks for visible signs of infestation, damage, and conditions conducive to termites. If an infestation is found, the seller is typically responsible for treatment and repairs. A treatment warranty can be transferred to the new owner, adding value. For buyers, a professional inspection before purchase can prevent unexpected costs. For real estate agents and property managers, understanding these regulations ensures smooth transactions and protects clients.
What affects the price
- Type and extent of infestation (subterranean vs. drywood; localized vs. widespread).
- Size of the property (square footage and number of stories).
- Construction type (crawlspace, slab-on-grade, basement) affecting treatment access.
- Location and regional termite pressure (e.g., Gulf Coast vs. Midwest).
- Treatment method chosen (liquid, bait, fumigation).
- Need for structural repairs or wood replacement after treatment.

What is your biggest concern about termites?
When to call for help
Call a professional immediately if you notice any signs of termite activity — mud tubes, swarming insects, hollow wood, or frass. For real estate transactions, a WDO/WDI report from a licensed inspector is often required. Early intervention can save thousands in repairs.
What you can do yourself
DIY termite control is rarely effective for eliminating an entire colony. Over-the-counter sprays and foams may kill visible termites but miss the colony underground or inside walls. Professional treatments use specialized equipment and termiticides that are not available to the public. Bait stations require proper placement and monitoring to work. For prevention, you can reduce moisture and remove wood-to-soil contact yourself. But if you suspect an active infestation, a licensed professional is the only reliable solution. The cost of professional treatment is far less than the cost of repairing structural damage.
Where you live matters
Swarms occur in spring, and treatment is often needed only when an infestation is detected. However, prevention is still key: maintaining proper drainage and avoiding wood-to-soil contact can reduce risk. In the West, drywood termites are prevalent in coastal regions. These termites do not require soil contact and can infest attic beams, furniture, and framing. Fumigation is the most effective treatment for widespread drywood infestations. Local building codes may require termite-resistant materials in new construction. Termite risk varies significantly by region. In the Southeast and Gulf Coast, the Formosan subterranean termite is a major threat, with colonies that can number in the millions. These termites are more aggressive than native species and can cause severe damage in as little as six months. Homeowners in these areas should consider continuous protection plans, such as bait stations or annual liquid treatments. In the Midwest and Northeast, native subterranean termites are common, but activity is more seasonal.
Simple ways to keep termites away
- Eliminate moisture: Fix leaky pipes, ensure proper drainage, and use dehumidifiers in crawl spaces.
- Remove wood-to-soil contact: Keep firewood, lumber, and debris away from the foundation.
- Seal cracks: Fill gaps in foundation, walls, and around utility lines with silicone caulk.
- Inspect regularly: Check for mud tubes, damaged wood, and swarmers annually, especially in spring.
- Use termite-resistant materials: Pressure-treated wood or concrete barriers for new construction.
- Maintain landscaping: Keep mulch at least 6 inches from the foundation and trim vegetation away from the house.
- Schedule professional inspections: Yearly inspections can catch problems early, especially in high-risk regions.
