Bed bugs and their eggs die when laundry reaches a sustained internal temperature of about 120°F (49°C), and a commercial dryer running on high heat is the most dependable way to reach it. For a hotel, the harder part is not the biology but the workflow around it: how you bag and move affected linen, how long each load stays in the dryer, and how the laundry step lines up with your pest control provider. This guide covers the temperatures that matter and the operating procedure a property needs so that hotel bed bugs are contained on the floor where they appear instead of being carried through the building.
The temperature that actually kills bed bugs
The thermal kill temperature for bed bugs is lower than most people expect. Adult bugs begin to die at around 113°F (45°C) with sustained exposure, and both the insects and their eggs are reliably killed at about 120°F (49°C) held for ten to twenty minutes. Eggs are the stubborn part of the problem. Bed bug eggs survival is what allows an infestation to rebound a week after a room looks clean, because eggs are glued to fabric and tolerate cold far better than adults do. This is why bed bug heat treatment aims for a margin above the minimum: you want the whole load, including the folds and seams where eggs hide, to pass through that lethal band, not just the outer layer.
There is an ongoing question of dry heat vs. hot water wash, and for linen the honest answer is that both help but the dryer does the decisive work. A hot wash raises the temperature of the water, but wet fabric in a large load does not always hold a uniform lethal temperature long enough to kill bed bugs at every point. Dry heat in a tumble dryer is more even and easier to sustain, which is why the dryer, not the washer, is the step you build your protocol around.
Why the dryer matters more than the wash
A clear dryer heat protocol is the single most important control a hotel has. Once linen is loaded, run the dryer on its highest safe heat setting for the fabric and hold it there for at least thirty minutes after the load is dry to the touch. The extra time matters because a packed load heats unevenly, and thick items such as duvets and mattress pads need longer for the core to catch up. Do not overload the drum. Bed bug heat only works when hot air can move through the load, so a half-full drum that tumbles freely kills more reliably than a stuffed one.
The wash still has a role. Washing removes soil, stains, and some bugs mechanically, and a hot cycle is sensible where the fabric allows it. But treat the wash as cleaning and the dryer as the kill step. When you frame the two that way, staff stop debating dry heat vs. hot water wash on the floor and simply follow the sequence: bag, wash if suitable, then dry hot and long.
Containment: bagging and moving infested linen
Most cross-contamination happens between the room and the laundry, not in the machines. Linen containment and bagging is the discipline that prevents it. Strip affected beds directly into a sealable plastic bag inside the room, close the bag before it leaves, and do not carry loose linen down a corridor or drop it into an open cart shared with clean stock. A torn or open bag on a housekeeping trolley is how hotel bed bugs move from one floor to the next.
Once bagged, affected linen should go into linen quarantine rather than back into general circulation. Keep a labeled holding area, ideally away from clean inventory, where flagged bags wait for the hot dry cycle. The bag stays sealed until it is opened directly at the washer or dryer, and the empty bag is discarded, not reused. This handling is unglamorous, but it is where a program succeeds or fails.
Building an infestation response checklist
When a room is flagged, staff should not have to improvise. A written infestation response checklist keeps the response consistent across shifts and languages. A workable version covers the essentials in order: take the room out of service, bag all soft goods in the room before removal, move sealed bags to linen quarantine, run the dryer heat protocol on every item, and hold the room for inspection before it returns to inventory.
The checklist only works alongside pest control coordination. The laundry step handles linen, but the room itself, including the mattress, frame, and baseboards, is the pest control provider's responsibility. Share the same trigger with them so that when housekeeping flags a room, the laundry response and the pest treatment start together rather than days apart. A property that treats the room but recirculates the linen, or the reverse, tends to see the problem return.
In-house vs. outsourced laundry for infested linen
The in-house vs. outsourced laundry decision comes down to whether your equipment can hit and hold the kill temperature reliably. Many on-premise dryers can, and for those properties an in-house protocol is fine as long as it is documented and followed. The risk with in-house handling is inconsistency across shifts, not the machines themselves.
Outsourcing to a commercial laundry changes the equation. A commercial bed bug laundry program uses tunnel washers and high-capacity dryers built to hold validated temperatures, and a professional hotel laundry service can log the cycle so you have a record that each load was treated. That documentation matters if a guest raises a claim. When you evaluate bed bugs laundry for hotels, ask whether the provider offers dedicated handling for flagged linen, because a commercial bed bugs laundry that mixes affected and clean stock offers no real advantage over doing it yourself. A serious commercial bed bug laundry keeps the two streams separate end to end.
What bed bug laundry costs, and how to find a provider
Owners reasonably want to know how much does bed bugs laundry cost before they commit. Bed bugs laundry cost is usually built into the per-pound or per-piece rate of a linen program rather than billed as a separate line, though some providers add a surcharge for the extra handling and the longer dry cycle that flagged linen requires. When you compare bed bugs laundry pricing, look past the headline rate to what is included: separate handling, sealed transport, and a treated-cycle record are worth more than a slightly lower number.
To find bed bugs laundry companies, start with the commercial linen providers already serving hotels in your area, since they understand hospitality volumes and turnaround. Searching bed bugs laundry near me will surface local options, but the best bed bugs laundry for a hotel is the one that can prove its process, not just claim it. Ask any provider to walk you through their containment, their dryer heat protocol, and how they document each treated load before you sign.
Common questions
How much does bed bugs laundry cost?
In most cases it is folded into your existing linen program rather than charged separately, so the real cost is the extra handling time and the longer, hotter dry cycle rather than a distinct fee. Where a provider does add a surcharge, expect it to reflect the sealed transport and the dedicated cycle that flagged linen needs. Ask for the treatment to be itemized so you can see exactly what the premium covers.
How long should linen stay in the dryer to kill bed bugs?
Run the highest safe heat for the fabric and hold it for at least thirty minutes after the load is dry, longer for thick items like duvets and mattress pads. The goal is to bring the entire load, including seams and folds, through the lethal band, so an underloaded drum that tumbles freely will outperform a packed one every time.
Can I wash bed bug linen with the rest of the hotel's laundry?
No. Flagged linen should be bagged at the bed, held in linen quarantine, and run on its own so that eggs and bugs are not spread to clean stock in a shared load. Keeping the two streams separate from room to machine is the whole point of the protocol, and it is the first thing a good provider will do for you.
