Learn when drywood fumigation is considered, what to ask about preparation and why reentry requires professional clearance.
What tenting does—and which termite problem it addresses
Tenting is the visible enclosure used in whole-structure fumigation. For homeowners, the important questions are why a whole-structure scope is proposed, which pest is being treated, what preparation is required and how reentry will be authorized. The tent is one part of a restricted-use treatment process, not a do-it-yourself control method.
Drywood colonies can live entirely inside wood, making concealed or widespread activity difficult to reach with localized work. Subterranean termites generally require a separate strategy directed at their access and colony biology. Seeing termites is not enough to decide whether the property needs tenting: identification and a documented inspection come first.
Termite treatment begins with identification, not the size of the insect or the room where it appeared. Drywood termites live within wood without a soil connection. Small, hard, six-sided fecal pellets beneath a kick-out opening can be a clue. Subterranean termites generally reach wood from soil, often through earthen shelter tubes. Flying ants can resemble termite swarmers: termites have a broad waist and two similarly sized pairs of wings, while ants have a pinched waist and unequal wing pairs. A qualified inspector should confirm the insect and the evidence.
Colonies contain feeding individuals, soldiers and reproductives. Seeing a swarmer does not reveal the location or extent of the feeding colony. One visible patch of damage may connect to concealed wood, and an insect near an open window may have arrived from outside. Photograph the location, note the date and explain what changed. Preserve accessible evidence for the inspector rather than spraying, painting over it or opening structural wood.
The distribution of drywood termites in Florida provides background; it cannot tell you the probability that one particular house is infested.
Knowing about drywood termite swarming in Florida helps interpret flying reproductives without treating a month or time of day as species identification.
Prepare occupants, food, medicines, plants and pets
Obtain the fumigator’s written product-specific preparation checklist before the job. Tell the provider about attached or connected structures, occupants’ access needs, pets, plants and belongings that may need special consideration. Arrange accommodation for the entire restricted period, with a plan for delays and medication access. Nobody may return to retrieve a forgotten item while entry is prohibited.
Ask exactly which food and medicines must be removed or packaged using approved materials. Do not improvise packaging based on ordinary plastic bags or assume every sealed container has the same requirement. Preparation for utilities, exterior access, vegetation and structural connections should be coordinated with the qualified parties named by the provider. Keep the emergency contact and reentry instructions available outside the home.
The written preparation checklist may require removing or using approved double bags for specified foods and medicines, unlocking and opening the designated cabinets, drawers, closets and interior doors for fumigator access, and leaving specified storage containers open. Confirm who must arrange that access or provide necessary keys under the actual product preparation checklist. Exterior preparation may include trimming shrubbery so tarps can fit and arranging separation from attached fences or decks. Ask which tasks the fumigator assigns to you, which require assistance, and what materials or access work are included in the quote. Follow the actual checklist and product instructions; qualified parties must handle utility work.
Include refrigerator and freezer contents in the food, feed and medicine checklist. For sulfuryl-fluoride structural fumigants, the UF manual distinguishes plastic, glass or metal bottles, cans and jars with their original manufacturer air-tight seal intact from items without that qualifying seal. The latter need removal or the operator-specified approved double-bagging procedure; an ordinary storage container or resealed package should not be assumed equivalent. Ask the fumigator to identify the approved bags and confirm the exact product instructions before preparing anything. The manual allows qualifying sealed food in closed refrigerators and freezers, so leaving food cold is a separate question from packaging protection. Product-specific medicine rules can differ; have the written checklist resolve the actual items instead of applying one rule to every fumigant.
Tell the fumigator specifically about aquariums and live fish. Before treatment, agree in writing whether the fish or tank will be removed or whether the operator will implement an approved tank-protection plan. The UF manual allows such a plan, so an aerator is not a reason to assume a tank can stay unchanged. Have the qualified operator resolve tank and fresh-air arrangements; do not improvise sealing or enter during the restricted period.
Ask the fumigator whether exterior foundation soil or the roots of plants that must be covered need watering, who will handle it and how it fits the product instructions. For sulfuryl-fluoride tarp fumigation, the UF manual explains that adequately moist exterior soil helps limit gas loss through the soil and root exposure; watering covered plants’ roots can reduce damage but does not guarantee protection. It specifically advises against watering the crawlspace subarea before fumigation because moisture can condense indoors. Follow the property’s written plan rather than applying one watering distance or schedule to every home.
Confirm with the fumigator that all flames, including gas-appliance pilot lights, will be extinguished and that any natural-gas or propane service will be shut off before treatment under the written product checklist. Agree who will coordinate each task with the local gas company or other appropriate authority and who is qualified to restore service afterward. The UF manual requires gas shutoff following local gas-company procedures and qualified restoration; do not disconnect, relight or restore a gas service yourself on the basis of this article.
Tell the fumigator about satellite dishes, antennas and their guidewires before tarping. Ask whether they need protection, temporary removal or another adjustment, and which qualified person should handle it. UF preparation guidance specifically calls for antenna guidewire removal when requested and lists roof attachments among tarping inspection concerns. The answer depends on the actual attachment and tarp plan; no universal dish-removal rule or roof access by the homeowner is implied.
During treatment: application, aeration and clearance
Whole-structure fumigation is an option for drywood colonies that are widespread, concealed or difficult to reach with localized work. A licensed fumigator encloses the structure and follows the product label and clearance requirements. This approach reaches a broader treatment scope than treating only a visible opening, but does not repair damaged lumber or leave a residual barrier against a later drywood infestation. It is also not a substitute for a subterranean-termite soil or bait program.
Residents, pets and plants must be out during the restricted period. Food, medication, connected structures and site access require the fumigator’s written preparation instructions. Return only after the certified applicator authorizes reentry and the required clearance is documented. A removed tarp, lack of odor or elapsed number of days is not clearance. Arrange accommodation and access around that process rather than assuming a standard two-day return.
Ask how the provider will document clearance and notify you of authorized reentry. EPA clearance guidance calls for instrument measurements in room breathing zones; sulfuryl fluoride cannot be judged by smell. The applicator must follow applicable current label requirements, including aeration and clearance procedures. A predicted completion day is a planning estimate, not permission to enter.
Do not enter when the tent has been taken down unless reentry has also been authorized. Do not use ventilation, cleaning or an absence of symptoms as substitutes for clearance. If you cannot confirm authorization, contact the fumigator and remain outside. The provider should explain who controls access and how a delay affects accommodation arrangements.
Scheduling separates application and exposure from aeration and instrument-based clearance. UC guidance relates the period away from a fumigated building to its volume and the amount of gas introduced. The fumigator determines those job-specific requirements under the applicable label; concealed scope, preparation and clearance also affect the plan. A size category, weather forecast or severity label cannot supply a universal return day. Confirm the expected schedule and contingency arrangements, then wait for professional authorization to reenter.
In structural fumigation, the licensed operator introduces fumigant gas into the enclosure and maintains the required concentration-and-time exposure before aerating and measuring clearance. Temperature and the pest life stage affect the label-based dose calculation; gas leakage, construction and access affect how the job is managed. Severe visible damage is not by itself a rule to increase dose, and structural complexity is not a fixed extra day. Separate how much enclosed volume must be dosed from exposure time and from the aeration/clearance period. Sulfuryl fluoride has different efficacy requirements for different pests and stages, so broader reach does not mean every egg in every crack is killed at a drywood-treatment dose.
Wind is a separate planning factor from temperature. The UF fumigation manual explains that increased wind can reduce gas confinement by increasing leakage; the professional must evaluate tarp sealing, construction and forecast conditions against the permitted job plan. Conditions can affect when a job can be performed as well as how exposure is maintained. That does not produce a fixed windy-day duration, a home-adjusted dose or permission to reenter before the required instrument-based clearance.
Cost and alternative methods: compare inspected scopes
Request a written quote based on the inspected property. It should identify the termite group, findings, affected areas, proposed method, inaccessible areas and follow-up responsibilities. Ask whether inspection, preparation assistance, any required access work and future visits are included. A lower total for one board is not directly comparable with a whole-structure scope; a broader method is not automatically appropriate simply because it costs more.
Keep damage repair separate from pest treatment. If framing, floors or other load-bearing components appear compromised, arrange an assessment by an appropriate building professional. Ask for separately stated treatment, repair and renewal amounts. For insurance questions, review the actual policy and contact the insurer; neither an article nor a pest-service agreement can establish a claim’s coverage. Financing, discounts and inspection fees require a current written offer.
Localized drywood treatment may involve removal or replacement of an infested item or labeled treatment of accessible galleries. A foam or liquid injection can affect the wood reached by that application; it cannot be assumed to reach every separate colony behind finished surfaces. Ask what evidence supports a localized scope, what could not be inspected and how nearby members will be assessed.
A useful localized-treatment proposal identifies the affected wood, treatment limits and follow-up plan. A single pellet pile does not necessarily mean the entire problem is limited to one board. Conversely, an isolated infested item does not automatically justify whole-house fumigation. The decision depends on confirmed infestation, access and confidence in the mapped extent. Structural replacement requires appropriate building expertise and does not resolve unnoticed colonies elsewhere.
Professional heat treatment is another drywood option in some situations. Its challenge is delivering the required exposure inside every infested piece of wood within the treatment scope. Room air temperature alone does not establish that a thick beam or a heat sink reached the necessary internal conditions. Sensitive materials, inaccessible areas and temperature monitoring must be considered before selection.
Heat does not leave a chemical residual against new infestation. It is not a reason to use a heat gun, household heater or sunlight as a substitute for a monitored treatment. Ask a provider whether it actually offers this method, which areas it can treat and how it verifies exposure. Availability of a method in an extension publication does not establish that On Demand Pest Control offers it.
For confirmed subterranean termites, compare liquid soil treatment with a maintained bait system rather than treating either as a drywood substitute. Labeled soil treatment addresses subterranean entry through treated areas; gaps or disturbed soil can change continuity. Baits use cellulose with a slow-acting insecticide and depend on termites finding and feeding on it, with system-specific monitoring and maintenance. A quote should distinguish initial treatment or station installation from continuing service, renewal and any follow-up work. Neither approach is a treatment of all drywood colonies concealed inside lumber.
Use fumigation cost considerations to organize questions about scope, preparation and temporary accommodation before comparing written offers.
The termite treatment cost discussion can help organize a quote comparison, but the property inspection determines the proposed scope.

After authorized reentry: monitor rather than assume immunity
Use evidence and records to decide what comes next. Keep the inspection report, identified species, treatment diagram, product information, preparation instructions and contract together. Establish what the provider will inspect at follow-up, which inaccessible areas remain and whom to contact if signs reappear. UF/IFAS recommends considering annual renewal inspections as part of home termite prevention; an inspection is different from automatically applying pesticide each year.
Photograph renewed pellets, wings, tubes or damaged wood with the location and date. Pellets can be dislodged from previously infested wood by vibration, so a new pile after treatment is a reason to ask for reassessment, not proof of failure on its own. New construction or disturbed soil also warrants review. A quiet period or a clean visible surface does not prove that every concealed colony is absent.
A termite bond is a service-contract term whose value depends on its written coverage. Under Florida section 482.227, the first page must clearly state whether the contract provides repair and retreatment, retreatment only, or no warranty or guarantee; limitations must also be disclosed. An inspection renewal, pesticide application and damage-repair obligation are different commitments.
Check covered termite groups, excluded conditions, renewal requirements, notice procedures, repair limits and transfer provisions. Do not assume drywood, Formosan and Asian subterranean termites are all included. Ask what happens after renovations, a lapse or sale of the property. A contract can define service and financial responsibilities, but it does not change a treatment’s biology or make future infestation impossible.
If you discover food, animal feed or medicine that was accidentally left without the required protection, keep it from use and contact the fumigator for the actual product’s label-based disposition. Give the item, packaging and exposure details rather than assuming it is usable because reentry has been authorized. Room-air clearance and the preparation requirements for consumable items are separate checks; do not apply a universal medicine-disposal rule.
After the fumigator has authorized reentry, ordinary housekeeping can include wiping countertops, tables and food-preparation surfaces with soap and water, following the provider’s written aftercare instructions. Keep that household task separate from instrument-based clearance: cleaning is not a way to authorize entry or establish that a restricted building is safe to enter.
After authorized reentry, ask the fumigator whether opening doors and windows is appropriate for your property and the actual product instructions. The UF fumigation manual describes this as optional post-return ventilation that may reduce the chance of encountering residual chloropicrin warning agent. Follow the written aftercare instructions and site conditions; household ventilation neither replaces professional aeration and instrument-based clearance nor authorizes entry into a restricted structure.
Document the location and date of possible signs of termites before disturbing evidence.
Plan after-fumigation follow-up around authorized reentry, the inspection record and any new evidence; a finished fumigation is not future-infestation immunity.
Read actual terms when evaluating termite bond coverage, including whether retreatment and damage repair are separate obligations.
Prevention after fumigation
Reduce conditions that favor access and make early signs easier to see. Repair plumbing and roof leaks, maintain drainage away from the foundation and avoid irrigation that repeatedly wets walls. Keep firewood, scrap lumber and other cellulose debris away from the structure. Avoid wood-to-soil contact and preserve a visible foundation inspection space rather than covering it with soil, thick mulch or stored materials.
For drywood risk, maintain screens, seal appropriate exterior gaps and keep exposed wood finishes in good repair. These steps can reduce opportunities for swarmers to enter but do not kill colonies already inside lumber. Borate treatments can protect accessible treated wood when the product is suitable and the wood is protected from weather; they do not make all surrounding untreated wood immune. Moisture repair and maintenance support treatment without replacing it.
Keep the documented pest and treatment scope in mind when later signs appear. A later swarmer may be an outside arrival or evidence requiring a new assessment; the calendar alone does not decide. Fumigation has no residual protection against a new drywood colony. Preventive repairs and a clear service plan therefore remain useful after the original infestation has been treated. A contract’s renewal or repair provisions need to be checked independently.

Frequently Asked Questions
-
How long do you have to stay out of your home during termite tenting?
Remain out for the full restricted period until the certified applicator authorizes reentry after required clearance. Preparation, application and aeration vary by the actual job and label. Arrange accommodation with flexibility rather than assuming a fixed two- or three-day absence.
-
Is termite tenting safe for my home's structure and belongings?
After proper aeration, the fumigant dissipates and leaves no residue; that differs from a guarantee that every item or part of the building cannot be affected. Follow the written instructions for foods, medicines and preparation-sensitive belongings. UC guidance notes possible roof damage from tarps or walking on a roof, so discuss material and access concerns before work begins. Only the required professional clearance authorizes reentry.
-
Does termite tenting kill all types of termites?
A drywood fumigation is not a complete subterranean-termite soil or bait program. Have the termite group and any coexisting infestation identified. The treatment proposal must explain the pest and scope it addresses instead of promising control of every termite type.
-
Can I do termite tenting myself or is a professional required?
Structural fumigation is restricted-use professional work. Florida requires a certified applicator to direct the process and authorize reentry. Do not attempt to enclose, fumigate or clear a home yourself. Ask a licensed provider for its inspection, preparation and clearance procedures.
-
How soon can termites return after tenting?
Fumigation leaves no preventive residual against new drywood infestation. There is no guaranteed termite-free period afterward. Maintain exclusion repairs, preserve records and request reassessment of renewed evidence; old pellets can also fall after wood is disturbed.
-
Will termite tenting get rid of other pests like roaches or bed bugs?
Sulfuryl fluoride has labeled structural-fumigation uses for pests including cockroaches and bed bugs, but a drywood-termite dose and preparation plan should not be assumed to control every other pest or life stage. Eggs and different target pests can require different exposures. Tell the licensed fumigator about the actual identified pests and have the treatment scope and label requirements confirmed; tenting does not provide a residual barrier against later arrivals.
