Heat treatment fails for one reason far more than any other: something in the room shielded the bugs from the heat.

What has to come out of the room
Every operator issues their own preparation instructions and theirs governs — this is the general shape of it so you know what you are agreeing to before the day arrives. Items in this list are either damaged by sustained heat or hazardous at those temperatures.
Pressurized containers
Aerosol cans, butane lighters, fire extinguishers, propane canisters, spray paint, and anything else under pressure. These are a genuine hazard at treatment temperatures and are non-negotiable removals.
Medication, cosmetics and consumables
Prescription and over-the-counter medication, vitamins, cosmetics, and anything with a storage temperature limit. Sustained heat can degrade active ingredients. Also remove alcohol, candles, wax items and chocolate.
Sensitive electronics and media
Vinyl records, cassettes and film, laptops and tablets, musical instruments — particularly anything with glued wood joints or gut and wound strings. Ask specifically about anything valuable rather than assuming.
Pets, plants and live animals
All pets, aquariums and houseplants leave the treatment area entirely, including fish tanks, reptile enclosures and insect habitats. Confirm the whole-house plan with the operator, not just the treated room.
Heat-sensitive valuables
Artwork, oil paintings, antiques with hide glue joints, candles, crayons, some plastics and adhesives, and anything with a wax or resin component. Photographs can stick together. When in doubt, take it out.
Firearms and ammunition
Ammunition must be removed. Check with the operator on firearms — policies and safe-storage arrangements vary, and this should be settled well before the treatment day rather than at the door.

What has to be done to what stays
Open everything so air moves
Thermal remediation depends on hot air circulating into every void. Drawers pulled out and left open, closet doors open, clothing rehung with space between hangers rather than compressed, luggage unzipped, and boxes opened and spread out. A tightly packed closet or a jammed dresser drawer is the classic cold spot — the room hits temperature and the inside of that drawer never does. Operators place remote sensors specifically to catch these, but they cannot open what you left locked.
Furniture pulled off the walls
Beds, dressers, nightstands and upholstered furniture moved several inches away from walls so air passes behind them, and headboards taken off the wall where practical. The wall-side of a headboard and the gap behind a heavy dresser are two of the most reliably infested and most reliably under-heated spots in a bedroom.
Laundry handled separately and correctly
Clothing and bedding that leaves the room needs to be treated rather than merely relocated, or you carry the problem back in. The standard approach is washing and then a full drying cycle on high heat, then sealing the clean items in bags until treatment is complete and the room is released. Items that cannot be hot-dried are usually best left in the room to be heated in place — ask the operator which of your items fall into which category.
Plan the day itself
Treatment typically runs a substantial part of a day once setup, heat-up, hold time and cool-down are counted, and nobody occupies the space during it. In Polk County’s summer, operators also have to manage the load this puts on a house in ambient heat, which can affect scheduling. Arrange somewhere for the household and pets to be, and do not plan to run in and out — opening the envelope mid-treatment undermines the hold.
What the operator does on the day
Set up heaters and air movers
Electric or propane-fired equipment plus fans positioned to drive hot air through the space and into voids rather than simply raising the room’s average temperature.
Place remote temperature sensors
Sensors in the coldest, most sheltered locations — inside the box spring, behind the headboard, in dresser interiors — monitored throughout so the operator is proving the hard spots reached temperature, not just the room.
Hold above the lethal threshold
Bed bugs and their eggs die from sustained exposure at temperatures well above normal indoor conditions; operators target a room temperature comfortably above that and hold it for a defined period while moving air and periodically disturbing harborage.
Inspect, cool down and advise on follow-up
Heat has no residual effect once the room cools, so many operators pair it with a targeted residual application or a follow-up inspection. Ask what the plan is for re-introduction from the source. See the heat vs. chemical comparison.
What decides the operator’s quote (we never set prices)
- Treated area and number of rooms — Equipment, power requirement and time on site scale with the volume being heated.
- Preparation state on arrival — A room that is not prepared to the operator’s sheet may need rescheduling or additional labor, and both cost money.
- Whether a follow-up or residual is included — Some quotes include a follow-up inspection or a companion residual treatment; some do not. Ask explicitly, because it is a common source of misunderstanding.

How the bed bug heat treatment dispatch works
Full transparency: Lakeland Exterminators is a dispatch and matching service, not a licensed pest control operator. Your request routes by ZIP to an independent, FDACS-licensed operator covering your part of Polk County; they own the inspection, treatment, pricing and any service warranty under Chapter 482, Florida Statutes. Verify any operator at the FDACS license search before you hire — honest companies expect it.
One point worth stating plainly: the preparation list on this page is generic guidance and your operator’s written instructions always take precedence. Equipment, target temperatures, hold times and prep requirements vary between companies, and following a checklist you found online instead of the one you were given is a common way for a treatment to go wrong.
Heat treatment preparation questions, answered straight
How long does bed bug heat treatment take?
Plan on most of a day for a typical residential job. The visible heating period is only part of it — setup and equipment placement, bringing the space up to temperature, holding it long enough for the coldest monitored point to reach and sustain the lethal threshold, then cool-down and inspection all take time. Larger homes or multiple-room treatments run longer. Your operator will give a realistic window for your specific job; treat any promise of a quick in-and-out with suspicion.
Do I have to leave the house during treatment?
You have to be out of the treated area, and in most residential jobs that means out of the house. So do pets, fish and plants. The space is held at temperatures well above habitable levels, and equipment is running throughout. Confirm with the operator whether unaffected parts of the house are usable during treatment — for a single-room job in a larger home it sometimes is, but do not assume.
Will heat damage my furniture or belongings?
Properly run treatments are designed not to, and most household furnishings tolerate it fine. The exceptions are the reason the prep list exists: pressurized containers, wax and candles, some plastics and adhesives, vinyl records and film, certain musical instruments, antiques assembled with hide glue, and anything with a stated temperature limit. Solid wood furniture, mattresses and normal clothing generally come through without issue. If you have something valuable and you are unsure, ask before the day rather than hoping.
Does heat treatment kill the eggs too?
That is its main advantage over some chemical approaches. Sustained heat at the temperatures used kills all life stages including eggs, which is why a correctly executed heat treatment can resolve an infestation in a single visit where a residual-only program may need repeat applications timed to egg hatch. The critical word is correctly — if a harborage point stayed below threshold because a drawer was packed shut or a closet stayed closed, eggs in that spot survive and the infestation restarts from there.
Do I need a follow-up treatment after heat?
Frequently yes, and a good operator will raise it themselves. Heat has no residual action — the moment the room cools it offers no ongoing protection. If the source of introduction is still active, or the property is a multi-family unit with neighboring activity, or there is any chance of a missed harborage area, a follow-up inspection and often a companion residual application around the treated area is normal practice. Ask what is included in the quote so there is no surprise.
Can I just do the prep partially and see how it goes?
This is the single most common reason a treatment underperforms, and it is worth being blunt about. The prep list is not a convenience request — opening drawers, unpacking closets and pulling furniture off walls is what allows heat to reach the places bed bugs actually are. A room that looks tidy but has a packed closet and a dresser against the wall can hit its target air temperature while the harborage stays fifteen or twenty degrees cooler. If the prep is genuinely beyond you, say so when booking; many operators offer prep assistance as a paid add-on.
Prepared properly, heat is a one-visit solution.
