Home/Termite Control

Professional Termite Control

Finding termites is one of the few pest problems where the bug is boring and the bill is not. Homeowners spend roughly $2 billion a year on subterranean termite treatment and prevention, a figure the University of Georgia Extension cites, and that leaves out most repair work. This page walks through the questions that decide what your job looks like: which termite you have, what your foundation lets them do, when they swarm in your zone, and whether a liquid barrier or bait system fits. The state guides linked from here get more specific.

Quick answer

Effective termite control starts by confirming the termite type and activity locations, then matching the structure to a documented treatment and monitoring plan. Soil treatments, bait systems, localized wood treatments and fumigation solve different problems; no single method is automatically right for every property. In PCT's 2025 termite market report (a survey of about 145 companies about 2024 operations), the average post-construction treatment price was $1,100 and 83% of company locations offered annual renewals, so ask what a renewal covers.

Key Takeaways

  • Confirm evidence and termite type before choosing treatment.
  • Fix moisture and wood-to-soil contact without assuming prevention removes an active colony.
  • Compare written scope, monitoring, exclusions, and warranty terms—not price alone.
  • Use only products labeled for the proposed structural application.
  • Research: In Pest Control Technology (PCT) magazine's 2025 termite market report (a Readex Research survey of roughly 145 pest-control professionals about 2024 operations), fumigation was among the least common termite services, offered by 16% of responding locations, a company-offering figure rather than an infestation rate.

Who This Is For

This guide is for anyone who has seen winged insects, mud tubes, or soft wood and wants to understand termite control before hiring someone. Homeowners get the most out of it, but landlords, buyers in escrow, and renters trying to figure out who pays will find the sections on regional rules and quotes useful too.

The Problem

The termite doing the damage in most American homes is the eastern subterranean termite, Reticulitermes flavipes, with the invasive Formosan termite added along the Gulf and southern coasts. Both live in soil colonies and reach wood through mud tubes over foundations or cracks in slabs and mortar you cannot see. UF/IFAS notes there can be 25 native subterranean colonies per acre, so the yard already has termites almost everywhere; the house's job is to not offer a path. Drywood termites are the exception. They fly straight into wood, need no soil contact, and matter mainly in Florida, coastal California, and the desert Southwest. Dampwood termites show up in the wet Pacific Northwest. The species changes the treatment: subterranean gets soil treatment, drywood gets fumigation, heat, or spot treatment, dampwood gets dried out. A mature native colony can hold 250,000 workers, per Texas A&M AgriLife, so years of quiet feeding can do real harm.

Warning Signs

  • Mud tubes on foundation walls
  • Hollow-sounding wood
  • Blistered paint on wood surfaces
  • Discarded wings near windows
  • Fecal pellets (drywood frass)

Risks of Waiting

  • Daily accumulating damage
  • Repair costs far exceed treatment costs
  • Structural integrity compromise
  • Colonies grow larger over time

Start with evidence, not a treatment preference

Termite control decisions improve when the inspection begins with observable evidence. Mud shelter tubes, discarded equal-length wings, live insects, frass associated with some drywood termites, and wood that probes abnormally can each narrow the diagnosis. The inspector should record where evidence appears and whether it indicates current activity, historic damage, or merely a conducive condition. A photograph is useful, but concealed galleries can extend beyond what a camera sees. Ask how the identification was made and which areas were inaccessible. The answer should distinguish subterranean termites that usually connect to soil from drywood termites that can live in wood without ground contact. That distinction changes the treatment map. A proposal written before anyone has looked at the foundation, crawl space, attic, additions, plumbing penetrations, and moisture conditions deserves skepticism. The goal is not to buy a famous treatment name. The goal is to connect a verified termite pathway to a method that can reach it and a monitoring plan that can show whether activity changes.

Match the method to the structure

Liquid soil treatments are intended to create treated zones that subterranean termites encounter as they move between soil and a building. Bait systems intercept foraging termites and require continued monitoring rather than a single placement visit. Localized wood or void treatments can be appropriate when activity is accessible and defined. Whole-structure fumigation addresses certain drywood termite situations but does not leave continuing protection after the building is cleared for reentry. Construction details complicate every option: attached slabs, wells, drainage systems, crawl spaces, additions, inaccessible voids, and nearby water can alter the plan. Ask the provider to draw or describe the proposed treatment zone, list areas that will not be treated, and explain how those gaps are handled. Product labels control legal application rates, locations, preparation, and reentry instructions. A useful recommendation explains why the selected approach fits the identified termite, the building, and the homeowner’s tolerance for monitoring, disruption, and recurring service.

Separate treatment, repairs, and prevention

Three different questions often get bundled into one sales conversation. First: is there active termite activity and how will it be controlled? Second: what wood or finishes have been damaged and who is qualified to evaluate repairs? Third: which moisture, drainage, landscaping, or construction conditions make future activity more likely? Pest-control technicians can document insect evidence, but structural engineering or appropriately licensed construction expertise may be needed when load-bearing damage is suspected. Correcting a leak or removing buried scrap wood is valuable prevention; it does not demonstrate that a hidden colony has been eliminated. Conversely, applying a termiticide without correcting chronic water problems leaves avoidable pressure around the structure. Request separate written findings for activity, damage, and conducive conditions. This keeps treatment claims from being confused with repair guarantees and gives the homeowner a usable maintenance list after service.

Compare providers and written protections

EPA consumer guidance recommends checking licensing and avoiding pressure tactics or claims of secret formulas and government endorsement. Obtain a written proposal that identifies the treatment, preparation, price, follow-up schedule, and safety instructions. For warranties, compare more than the number of years. Determine whether annual inspections or renewal fees are required, whether coverage is retreatment-only or includes defined repairs, which parts of the property are excluded, whether the agreement transfers to a buyer, and what renovations could void it. Ask how activity will be documented at later visits. A low opening price can become expensive if monitoring, renewal, or inaccessible areas are omitted. A higher proposal is not automatically better either. The defensible choice is the provider who connects evidence to a complete scope, answers label and safety questions clearly, and puts limitations in writing before work starts.

A practical homeowner decision worksheet

Before the inspection, write down every location where wings, tubes, pellets, damaged wood, moisture, or prior repairs were noticed. Add the dates of previous treatment, the provider, the method, and whether a warranty remains active. During the visit, ask the inspector to mark confirmed evidence, suspected routes, inaccessible areas, and conducive conditions separately. Afterward, compare the proposed treatment against that map. Each action should have a reason: a station belongs in a documented monitoring pattern; a soil treatment belongs along a defined route; a localized wood treatment belongs at accessible activity; fumigation belongs to a structure-wide drywood strategy rather than a generic fear response. Record preparation, reentry, follow-up, monitoring, and homeowner maintenance in the same worksheet. If a second bid recommends a different method, ask both providers to explain the difference using the property evidence. The worksheet is complete only when you can answer five questions without marketing language: What termite is suspected or confirmed? Where is the supporting evidence? Which parts of the structure are included or excluded? How will the treatment reach the problem? What observation or scheduled visit will show whether the plan is working? This discipline does not guarantee a particular outcome, but it makes proposals comparable and helps prevent an urgent concern from turning into an undefined recurring contract.

The research on termites in U.S. homes

Homeowners often ask whether a termite problem is unusual and whether a quoted price is normal. Public research cannot answer either question for one house, but it does set expectations. Here is what the sources report. In Pest Control Technology (PCT) magazine's 2025 termite market report, a Readex Research survey of roughly 145 pest-control professionals about 2024 operations, 57% of responding locations offered borate wood treatments, a company-offering share rather than a measure of household termite activity. A homeowner hoping to hire someone to physically block termite entry points may need to shop around: 19% of locations in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 professionals, 2024 operations) offered exclusion, a share of companies, not an infestation statistic. In the NPMA/Harris Poll findings released March 24, 2026, just one in five U.S. homeowners, 20%, thought termites were common where they lived; the figure captures beliefs, not inspection data or regional prevalence. termites rank near the top of homeowner worries, with 72% of respondents to HomeTeam Pest Defense's 2022 online survey of U.S. homeowners saying a discovery would concern them, a self-reported figure from a provider-sponsored poll rather than an infestation rate. For a property manager, the sobering number is that pests can end a tenancy: 7% of respondents in ConsumerAffairs' February 2024 survey of 2,000 U.S. respondents reported permanently leaving a home over pests, a self-reported finding from a mixed pest-and-mold survey, not an infestation rate. Use these numbers as context, not as a diagnosis. A provider's written inspection findings should drive the treatment plan, and any quote should spell out how many visits, which areas and what follow-up it covers.

Read the video transcript

Look for mud tubes, discarded wings, hollow-sounding wood, or blistered surfaces. One sign alone does not confirm the extent of activity. A professional inspection checks foundations, moisture conditions, accessible framing, and other likely entry points before recommending treatment. Bait stations are one treatment option. Placement, monitoring schedule, termite species, and building conditions determine whether they fit the property. Ask for written findings, the proposed treatment zone, follow-up schedule, warranty terms, and the limits of any repair recommendation.

What is your biggest termite-control question?

When to Call a Professional

Call when you find mud tubes, indoor swarmers, or damaged wood, because none of those go away on their own and the products that fix them are not sold to homeowners in useful form. An inspection matters even more when you are buying or selling in a state with wood-destroying insect report rules, when the house sits on a slab and you cannot see the sill plate, or when a neighbor was just treated. A few swarmers outside on a spring evening can wait a week; schedule an inspection before the season ends.

DIY vs Professional

DIY has a real place in termite control, just not in the treatment. You can fix the conditions that invite subterranean termites: pull mulch and soil back from siding, fix downspouts, get firewood off the ground, vent a damp crawlspace. Those changes cut pressure for every species. What you cannot do well is treat. A liquid barrier only works when it is continuous, which means trenching to the footing and drilling every slab that touches the foundation. Hardware-store bait stakes lack the monitoring that makes commercial systems work, and there is no consumer fumigation. Do the prevention yourself and let a licensed applicator handle the chemistry.

Local Context

Termite pressure in the United States tracks warmth, moisture, and how houses meet the ground. The Gulf and Southeast carry the heaviest load: year-round activity, Formosan termites along the coast, and slab and crawlspace housing, which is why Florida, Georgia, and North Carolina regulate termite reports in home sales. The Mid-Atlantic and Midwest deal with the eastern subterranean termite on a spring cycle, entering through basements and porches. The desert Southwest gets drywood and desert subterranean species that fly on monsoon evenings, and California adds coastal drywood pressure under a state licensing board. The Pacific Northwest sees dampwood termites in wet wood, and the northern Rockies and Alaska see little termite activity at all.

Prevention Tips

  • Keep six inches of visible foundation between soil or mulch and any wood siding or trim.
  • Route downspouts and sprinkler heads so water runs away from the foundation, not against it.
  • Store firewood and lumber on a rack at least 20 feet from the house.
  • Vent or encapsulate crawlspaces so wood moisture stays below the level subterranean termites need.
  • Replace wooden fence posts, deck supports, and lattice that touch soil with metal or treated bases.
  • Seal cracks where plumbing enters the slab, since termites follow pipes up into the wall.

💡 Did You Know?

  • Termite swarmers have wings that are roughly equal in length; flying ants have front wings longer than their hind wings. (U.S. EPA)
  • Products that kill only termites they directly contact have not necessarily demonstrated that they can protect an entire structure. (U.S. EPA)
  • State agencies regulate and license companies that perform structural termite work. (U.S. EPA)

Frequently Asked Questions

How do I know if I have termites?
Signs: mud tubes, hollow wood, discarded wings, blistered paint. Professional inspection provides definitive diagnosis.
Does insurance cover termite damage?
Almost never. Termite damage is considered preventable and is excluded from standard policies.
Can a photograph confirm the full termite problem?
A clear photograph can help distinguish a likely termite from an ant or show a mud tube, but it cannot map concealed activity or structural damage. An on-site inspection is needed to define treatment scope.
Should I break open a mud tube?
Avoid widespread disturbance. Photograph the tube and its location first. A professional may inspect a small section and check whether termites rebuild it, but breaking every tube can remove useful evidence without eliminating the colony.
Does every termite problem require tenting?
No. Whole-structure fumigation is associated mainly with certain drywood termite situations. Subterranean termite plans commonly use soil treatments, localized work, bait systems, or combinations selected after inspection.
What should a termite proposal include?
Look for the identified or suspected termite type, evidence locations, treatment areas, product or system, preparation, monitoring, follow-up, price, exclusions, and written warranty conditions.
Are termite warranties all the same?
No. Renewal fees, inspection frequency, retreatment, repair coverage, transferability, exclusions, and property-change requirements vary. Read the actual contract rather than relying on the word warranty.
Can moisture correction replace treatment?
Correcting leaks, drainage, and wood-to-soil contact reduces conditions that favor termites, but it does not prove an active colony is gone. Prevention and treatment address different parts of the risk.
Can I treat termites myself instead of hiring a professional?
Few homeowners want to. In research from the National Pest Management Association (NPMA) and Harris Poll released March 24, 2026, only 16% of U.S. homeowners said they preferred do-it-yourself termite control or prevention over professional help, a stated preference rather than a record of what they did. Termite treatment usually involves soil-applied termiticides or bait systems that require training and equipment, and many state regulations restrict the products available to consumers. Getting at least one professional inspection before deciding is the sensible baseline.
What is a termite renewal contract?
It is an annual agreement, sold after an initial treatment, that typically keeps a warranty and periodic inspections in force for a yearly fee. Renewals are standard: in Pest Control Technology magazine's 2025 State of the Termite Market report, a BASF-sponsored Readex survey of about 145 pest-control professionals on 2024 operations, 83% of responding company locations offered them. That describes what companies sell, not how many homeowners sign up. Before renewing, check whether the contract covers re-treatment only or also repairs.
