The short version
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.
- 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.
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.
What to look for
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.

Prices are typical published ranges. Ask what’s included before you compare quotes.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.Start with evidence, not a treatment preference.
Ask how the identification was made and which areas were inaccessible. A photograph is useful, but concealed galleries can extend beyond what a camera sees. The inspector should record where evidence appears and whether it indicates current activity, historic damage, or merely a conducive condition. 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. Termite control decisions improve when the inspection begins with observable evidence. 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. The goal is not to buy a famous treatment name. A proposal written before anyone has looked at the foundation, crawl space, attic, additions, plumbing penetrations, and moisture conditions deserves skepticism. That distinction changes the treatment map. The answer should distinguish subterranean termites that usually connect to soil from drywood termites that can live in wood without ground contact.
termites activity by season.
In Termite Control, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure usually turns up the conditions that are letting them in. The most useful first step in Termite Control is to note where you have seen termites and when they appear, because that timeline is what lets a provider focus on the right area instead of treating the whole property. Scheduling before the busy stretch, rather than after it, tends to mean faster service and a more accurate quote, and a local provider can point out the conditions that matter most in Termite Control.
A slow leak under a sink keeps the wood damp, and damp wood is exactly what termites are looking for.Match the method to the structure.
Whole-structure fumigation addresses certain drywood termite situations but does not leave continuing protection after the building is cleared for reentry. Localized wood or void treatments can be appropriate when activity is accessible and defined. Bait systems intercept foraging termites and require continued monitoring rather than a single placement visit. Liquid soil treatments are intended to create treated zones that subterranean termites encounter as they move between soil and a building. 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. Product labels control legal application rates, locations, preparation, and reentry instructions. Ask the pro to draw or describe the proposed treatment zone, list areas that will not be treated, and explain how those gaps are handled. Construction details complicate every option: attached slabs, wells, drainage systems, crawl spaces, additions, inaccessible voids, and nearby water can alter the plan.
Separate treatment, repairs, and prevention.
Third: which moisture, drainage, landscaping, or construction conditions make future activity more likely? Second: what wood or finishes have been damaged and who is qualified to evaluate repairs? First: is there active termite activity and how will it be controlled? Three different questions often get bundled into one sales conversation. Request separate findings for activity, damage, and things that attract termites. Conversely, applying a termiticide without correcting chronic water problems leaves avoidable pressure around the structure. Correcting a leak or removing buried scrap wood is valuable prevention; it does not demonstrate that a hidden colony has been eliminated. Pest-control technicians can document insect evidence, but structural engineering or appropriately licensed construction expertise may be needed when load-bearing damage is suspected.
Compare pros and written protections.
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. For warranties, compare more than the number of years. Obtain a written proposal that identifies the treatment, preparation, price, follow-up schedule, and safety instructions. EPA consumer guidance recommends checking licensing and avoiding pressure tactics or claims of secret formulas and government endorsement. The defensible choice is the pro who connects evidence to a complete scope, answers label and safety questions clearly, and puts limitations on paper before work starts. A higher proposal is not automatically better either. A low opening price can become expensive if monitoring, renewal, or inaccessible areas are omitted. Ask how activity will be documented at later visits.
A practical homeowner decision worksheet.
Record preparation, reentry, follow-up, monitoring, and homeowner maintenance in the same worksheet. 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. Afterward, compare the proposed treatment against that map. During the visit, ask the inspector to mark confirmed evidence, suspected routes, inaccessible areas, and things that attract termites separately. Add the dates of previous treatment, the pro, the method, and whether a warranty remains active. Before the inspection, write down every location where wings, tubes, pellets, damaged wood, moisture, or prior repairs were noticed. What observation or scheduled visit will show whether the plan is working? How will the treatment reach the problem? Which parts of the structure are included or excluded? Where is the supporting evidence? The worksheet is complete only when you can answer five questions without marketing language: What termite is suspected or confirmed? If a second bid recommends a different method, ask both pros to explain the difference using the property evidence.

What is your biggest termite-control question?
When to call for help
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.
What you can do yourself
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. 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.
Where you live matters
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. Termite pressure in the United States tracks warmth, moisture, and how houses meet the ground. The Pacific Northwest sees dampwood termites in wet wood, and the northern Rockies and Alaska see little termite activity at all. 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 Mid-Atlantic and Midwest deal with the eastern subterranean termite on a spring cycle, entering through basements and porches.
Simple ways to keep termites away
- 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.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
Termite swarmers have four wings all about the same length. Flying ants have front wings longer than the back pair.
A spray that kills only the termites it touches hasn't shown it can protect a whole house.
Companies that do structural termite work have to be licensed by the state.
Questions people ask
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. Only an on-site inspection can show how much treatment is needed.
Should I break open a mud tube?
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. Photograph the tube and its location first. Avoid widespread disturbance.
Does every termite problem require tenting?
Subterranean termite plans commonly use soil treatments, localized work, bait systems, or combinations selected after inspection. Whole-structure fumigation is associated mainly with certain drywood termite situations. No.
What should a termite proposal include?
Look for the suspected termite type, where the evidence was found, the areas to be treated, the product or system, preparation, monitoring, follow-up, price, what's excluded, and the warranty terms.
Are termite warranties all the same?
Read the actual contract rather than relying on the word warranty. Renewal fees, how often they inspect, retreatment, repair coverage, whether it transfers to a buyer, what's excluded, and rules about property changes all vary. No.
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?
In Termite Control, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Termite Control, 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.
