The short version
Termites cause $5 billion in damage annually in the US. For property managers, professional treatment (liquid or bait) costs $1,200-$3,000, with annual inspections essential.
- Termites cause $5 billion in property damage yearly; most insurance doesn't cover it.
- Spring swarm season (March-May) is peak activity; southern regions face year-round pressure.
- Professional treatments range from $1,200-$3,000; fumigation can reach $8,000.
- Many states require termite inspections (WDO/WDI) for real estate transactions.
- Ask any licensed pro what an inspection costs and what their warranty covers.
For homeowners, real estate agents, property managers, and landlords who need to understand termite control from a professional perspective. Whether you're buying, selling, or managing multiple units, you'll find actionable information on detection, treatment, and prevention—plus how to line up an inspection.
What to look for
The Formosan subterranean termite, particularly aggressive along the Gulf Coast, can destroy a home's structure in years. For property managers, an undetected infestation can lead to expensive repairs, tenant complaints, and even legal liability if not disclosed during sale. Termites are estimated to cause $5 billion in property damage annually in the United States. Most homeowners insurance policies do not cover termite damage, leaving property owners to foot the bill. Subterranean termites, the most common type, build mud tubes and require moisture, while drywood termites infest dry wood directly.
- 1Mud tubes on foundation walls, floor joists, or crawl spaces (subterranean termites).
- 2Wood that sounds hollow when tapped or blisters in floorboards.
- 3Discarded wings near windows or doors (swarmers shed wings after mating).
- 4Frass (termite droppings) that look like small pellets or sawdust.
- 5Tight-fitting doors or windows that become difficult to open due to warped frames.
- 6Buckling paint or crumbling drywall with faint, maze-like patterns.
Why it’s worth acting soon
- Structural damage can compromise load-bearing walls, leading to costly repairs.
- Damage may go unnoticed for years, escalating repair costs exponentially.
- Infestations can spread to adjacent units, increasing treatment plan and cost.
- Tenant dissatisfaction and potential legal issues if health hazards arise.

Liquid Soil Treatment
$1,200-$2,500
A liquid termiticide is applied to the soil around the foundation, creating a continuous barrier. It kills termites on contact and can last 5-10 years.
- Time
- Several hours to 1 day; protection lasts years.
- Best for
- Subterranean termites; new construction or existing homes with accessible perimeter.
Bait Stations
$1,500-$3,000 initial; annual monitoring $300-$500
Stations are placed in the ground around the property. Termites consume bait and share it with the colony, eliminating the queen. Requires monitoring.
- Time
- Ongoing; colony elimination may take months.
- Best for
- Properties with large colonies or where soil treatment is not feasible.
Wood Treatment (Borates)
$500-$1,500 per application
Borates are applied to exposed wood surfaces, penetrating to kill termites and prevent future infestations. Used during construction or renovations.
- Time
- Lasts indefinitely if wood remains dry.
- Best for
- New construction, attics, crawl spaces, or pre-treatment of wood.
Fumigation (Tenting)
$2,000-$8,000
The entire structure is sealed and filled with sulfuryl fluoride gas. Kills all termites inside, including drywood termites. Requires evacuation for 2-3 days.
- Time
- 24-72 hours; structure must be vacated.
- Best for
- Severe drywood termite infestations; whole-house treatment.
Prices are typical published ranges. Ask what’s included before you compare quotes.
Drywood termites can fly straight into attic framing through vents, so attics belong on the inspection list in warm climates.Understanding Termite Biology and Behavior.
The queen can lay thousands of eggs per day, and colonies can persist for decades, containing millions of individuals. They digest wood with the help of protozoa and bacteria in their guts—a symbiotic relationship. Subterranean termites build mud tubes to travel from soil to wood, protecting them from dry air. Drywood termites don't need soil contact and infest dry wood directly. Swarmers (alates) emerge in spring to mate and start new colonies. For property managers, understanding that termites are always looking for food (cellulose) means that any wood in contact with soil or moisture is at risk. Termites are social insects living in colonies with a queen, workers, soldiers, and reproductives.
Regional variations in Termite Pressure.
In the South (Gulf Coast, Southeast), the Formosan subterranean termite is especially destructive, with colonies that can eat through wood faster. The peak swarm season is March-May, but warmer climates see year-round pressure. In the Midwest and Northeast, native subterranean termites are common, with swarms in spring. Drywood termites are more common in coastal areas from the Carolinas to California. Property managers in high-risk zones should consider quarterly inspections and continuous baiting programs. In the West, the Western drywood termite is prevalent, requiring different treatment approaches. Termite activity varies by region.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.Regulatory Requirements for Property Managers.
Many states require a Wood Destroying Organism (WDO) inspection (also called a termite inspection) before a property can be sold or refinanced. This report must be completed by a licensed inspector, detailing any evidence of infestation or damage. Property managers should be aware that failure to disclose known termite issues can lead to legal liability. Additionally, some states have specific laws about pesticide application, requiring certified applicators for certain treatments. Always ensure your pest control pro is licensed and insured, and ask about warranties that cover re-treatment if termites return within a specified period.
What affects the price
- Size of property and extent of infestation.
- Type of termite (subterranean vs. drywood; Formosan more expensive).
- Treatment method (liquid, bait, wood treatment, fumigation).
- Accessibility (crawl spaces, slab vs. basement).
- Number of structures to treat (main house, garage, sheds).
- Local labor rates and regulatory requirements.
- Warranty terms (re-treatment costs).

What is the biggest challenge you face with termite control?
When to call for help
If you see any signs of termites—mud tubes, damaged wood, swarmers. a licensed pest control professional immediately. Property managers should also schedule annual inspections, especially in high-risk regions. Many states require a termite inspection (WDO/WDI report) before real estate transactions. Delaying can turn a $1,000 problem into a $10,000 repair.
What you can do yourself
Professionals have access to termiticides that last years, can identify the termite species, and offer warranties. However, prevention measures like reducing moisture and removing wood debris can be done by property owners. DIY termite control is rarely effective for active infestations. Over-the-counter sprays may kill visible termites but won't reach the colony. Bait stations and soil treatments require proper placement and monitoring to work.
Where you live matters
Termite pressure varies significantly across the US. In the Gulf Coast and Southeast, the Formosan subterranean termite is a major threat, often requiring specialized treatments like baiting systems. Spring swarm season starts as early as February in Florida, while in the Northeast, it peaks in April-May. Property managers in California must contend with drywood termites, which can infest attic wood and require fumigation. In the Midwest, subterranean termites are common, with soil treatments being the standard. The most useful first step in Property Managers is to note where you have seen termites activity and when it appears, so an inspection is faster and the quote more accurate. In Property Managers, checking the usual entry points, moisture spots, and sheltered areas near the structure usually turns up the conditions that are letting them in. A local provider who knows Property Managers can point out the specific things that matter most here before you commit to a plan.
Simple ways to keep termites away
- Eliminate moisture: fix leaky pipes, ensure gutters drain away from foundation.
- Keep wood, mulch, and debris at least 6 inches away from the foundation.
- Seal cracks in concrete and around utility lines entering the home.
- Replace any wood that contacts soil with pressure-treated lumber.
- Remove dead trees, stumps, and woodpiles from the property.
- Install termite barriers during new construction or renovations.
- Schedule annual professional inspections, especially in spring.

A single termite queen can lay up to 30,000 eggs in one day.
Termites have been around for well over 100 million years, long before humans.
Termites leave scent trails that guide the rest of the colony to a good piece of wood.
Questions people ask
How can I tell if I have termites or ants?
Termite swarmers have four equal-sized wings that break off easily, while ants have pinched waists and bent antennae. Termite wings are uniform in size; ant front wings are larger than back wings.
Does homeowners insurance cover termite damage?
Most policies consider termite damage preventable and exclude it. You must buy separate termite protection or cover repairs out of pocket. Almost never.
How long does termite treatment last?
Wood treatments (borates) last indefinitely if the wood stays dry. Fumigation kills all termites but offers no residual protection. Liquid soil treatments can last 5-10 years. Bait stations require ongoing monitoring.
What is a WDO inspection?
Many states require it for real estate transactions. The inspector issues a report detailing any evidence of infestation or damage. A Wood Destroying Organism (WDO) inspection is a visual check for termites, carpenter ants, and wood rot.
Can I treat termites myself?
You can buy sprays and foams, but they won't reach the colony. Professional treatments use termiticides that are not available to the public and include warranties. DIY treatments are rarely effective for active infestations.
How often should I have a termite inspection?
In high-risk areas (Gulf Coast, Southeast), consider every 6 months. After treatment, follow the pest control company's recommended schedule for re-inspections. At least once a year.
What are mud tubes?
They are a clear sign of infestation. Breaking a tube and seeing active termites confirms the problem. Mud tubes are pencil-sized tunnels built by subterranean termites to travel from soil to wood.
How much does termite damage cost to repair?
Minor damage might cost a few hundred dollars, but structural repairs can exceed $10,000. The average cost of termite treatment and repair is around $3,000, but fumigation can reach $8,000. Repair costs vary widely.
Is termite fumigation common?
In Property Managers, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Property Managers, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
