Stored clothes or luggage, 21 °C: adults average 64–112 days without feeding; most of the hardiest stage dead after about 144 days (Johnson 1941; Polanco et al. 2011). Kill them: dryer on high for 30 minutes (University of Minnesota) or a 60 °C wash (Naylor & Boase 2010). Freezer: 80 hours (3.3 days) at 0 °F; at least 3.5 days recommended (Olson et al. 2013). On your body: they don't stay — they hide nearby (University of Kentucky).
How long do bed bugs live on clothes?
Clothes give bed bugs a hiding place, not a meal. A bed bug tucked into the seam of a shirt survives only as long as it can go without blood, and that depends on the temperature around it. In a wardrobe at about 21 °C (70 °F), adults average 64–112 days without feeding, most bugs of the hardiest stage are dead after about 144 days, and the longest single bug measured near that temperature lasted about 184 days (Johnson 1941; Polanco, Miller & Brewster 2011). So the short answer to how long do bed bugs live on clothes is: weeks to a few months in a heated home, and longer in a cool one.
The catch is the word "alone". Clothes in a laundry basket beside an occupied bed are not a starvation chamber: most bed bugs live within 8 feet of where people sleep and can travel over 100 feet in a night (CDC), so a bug in a pile of clothes can walk to the bed, feed for a few minutes and come back. The clock only runs while the clothes are sealed away from people and pets.
Whether you ask how long can bed bugs live on clothes, how long can bed bugs live in clothes or how long do bed bugs live in clothes, the figures below apply. They are the same no-host figures our starvation calculator uses, picked for places where clothes are usually stored:
| Temperature | Typical place | Adults (average) | Most of the hardiest stage dead after | Longest single bug |
|---|---|---|---|---|
| 13 °C (55.4 °F) | Unheated loft or spare room | 179–360 days | 463 days | 562 days |
| 18 °C (64.4 °F) | Cool wardrobe | 99–152 days | 195 days | 268 days |
| 21 °C (69.8 °F) | Wardrobe in a heated home | 64–112 days | 144 days | 184 days |
| 26.3 °C (79.3 °F) | Warm room or summer storage | 43–99 days | 128 days | 143 days |
Notice that the cool loft keeps them alive longest. Bed bugs burn their reserves and lose water more slowly in cool air, so a box of clothes in an unheated room at about 13 °C can harbour live bugs for close to a year. Warmth shortens the wait but never makes it short.
Can bed bugs live in clothes?
Yes — as a hiding place. The CDC says bed bugs spread by getting into "the seams and folds of luggage, overnight bags, folded clothes, bedding, furniture". Researchers at the University of Sheffield found that worn clothing is "significantly more attractive than clean clothing" to bed bugs moving around a room, and suggested that dirty laundry left out while travelling helps them hitch a ride home (Hentley et al. 2017). What clothes can't do is keep a colony going on their own: without a person or pet nearby there are no meals, so no growth and no eggs.
Can bed bugs live in clothes you're wearing?
Not for long. Bed bugs are not like lice or fleas. The University of Kentucky's extension entomologist puts it plainly: they "normally do not reside on or attach to people like lice or ticks; immediately after feeding they crawl to a secluded location to digest their meal". A 2021 study adds that bed bugs "do not rest or reside on their host, but instead shelter in close proximity to the host", usually within a metre of where a person sleeps (Gaire et al. 2021). Warm, moving clothing on a body is exactly the kind of place they leave.
They can, however, use what you wear as transport. Can bed bugs travel on clothes you're wearing? The University of Minnesota lists bed bugs arriving as "hitch-hikers on you or your visitors clothing, shoes and bags", and Penn State notes that travellers carry them "in clothing, luggage, and laptop or tablet cases". A bug that crawls onto a coat on a sofa, or into a turn-up of trousers, can drop off later wherever you sit or undress.
Do bed bugs stay on your clothes?
Do bed bugs stay on your clothes once you've walked out of an infested place? Usually they don't stay long, and the risk from simply visiting is lower than many people fear. Bed bugs don't fly, and they don't "jump onto people and pets as fleas do"; during the day they normally stay hidden, so "the chance of picking up bed bugs by simply walking into an infested dwelling during the day is unlikely" (University of Kentucky). The same publication suggests simple precautions for carers and visitors:
- Sit on a hard chair rather than a sofa or bed, and put bags and coats on a table, away from bedrooms.
- Avoid leaning or brushing against beds and upholstered furniture.
- Back home, hot-wash or run clothing and shoes through a dryer.
How long can bed bugs live in luggage?
How long can bed bugs live in luggage? Exactly as long as in clothes: a suitcase is just another hiding place with no food. At room temperature that is weeks to a few months; in a cold garage or a loft it can be close to a year. What changes is where the bugs sit. A 2017 study at the University of California, Irvine, put adult bed bugs on the outside of soft suitcases: over 24 hours at room temperature, only 3% (5 of 170) moved inside, and while the cases were being heated only one bug of 250 crossed a closed zipper (Loudon 2017). Bugs that do get in are hard to see — Kentucky's guidance is that "inspecting or vacuuming suitcases is less useful since it is difficult to spot bed bugs in luggage".
That is why the experts focus on keeping luggage away from the bed rather than on searching it afterwards. The EPA advises storing suitcases "away from your bedroom, such as in the basement or garage. Never store suitcases under your bed." A suitcase that may have picked up bugs can be heat-treated — "a hot car can often do the trick in summer", according to Kentucky, if a thermometer shows at least 120 °F (49 °C) wherever bugs could hide — or thrown away. For how a parked car heats up, see our car checker.
Bed bugs in a suitcase: what to look for
Signs of bed bugs in suitcase linings are the same as on a mattress: live bugs, pale shed skins, tiny pearl-white eggs about 1 mm long and small dark spots of droppings, usually in seams, zipper tracks, pockets and the folds of the lining (EPA; CDC). A torch and a credit card slid along seams help. Finding none doesn't prove the case is clean, so treat the contents as the priority: they can go straight into a dryer.
How to kill bed bugs in clothes: washer, dryer and freezer
How to kill bed bugs in clothes: heat is the simplest and most reliable home method, and the dryer does most of the work. Studies and extension guidance agree on these steps:
| Item | Best method | Alternative |
|---|---|---|
| Washable clothes & bedding | Hot wash, then dryer on high for at least 30 minutes | A 60 °C (140 °F) wash on its own also killed every stage |
| Dry-clean only | Dryer on at least medium–high for 30 minutes while dry, then to the cleaner | Professional dry cleaning kills all stages; warn the cleaner |
| Shoes, bags, backpacks, soft toys | Dryer for 30 minutes at medium–high or the highest heat they tolerate | Bag and freeze at 0 °F: 80 hours (3.3 days) for every stage |
| Can't be heated at all | Bag and freeze, if freezing won't damage it | Or keep it sealed in a bag until every bed bug has died (see the table above) |
- Washing: washing at 60 °C (140 °F) killed every life stage, eggs included, while soaking for 24 hours did not kill eggs (Naylor & Boase 2010). Kentucky recommends 120 °F (49 °C) as the minimum wash temperature. Penn State warns that "laundering in cold water and drying at lower temperatures might not kill bed bugs", and the EPA says "just washing will generally not kill bed bugs" — so always follow a cool wash with a hot dry.
- Drying: tumble drying hot for at least 30 minutes killed all stages (Naylor & Boase 2010). The University of Minnesota says "simply putting infested items in the dryer for 30 minutes on high heat will kill all the bed bugs" — no wash needed.
- Freezing: for things that can't take heat, bag them and freeze at 0 °F (−17.8 °C). Our temperature calculator gives 80 hours (3.3 days) for every stage at that setting, and researchers recommend at least 3.5 days to allow for real freezers (Olson et al. 2013); exact temperatures are on what temperature kills bed bugs.
How long to dry clothes to kill bed bugs
How long to dry clothes to kill bed bugs? Thirty minutes on high is the figure to use. Sources give slightly different numbers because dryers and loads differ: the University of Minnesota says 30 minutes at the highest heat the item can withstand; Penn State says "15 to 30 minutes" at a high temperature and that "temperatures of 131º F or above are lethal to all bed bug stages"; Nebraska Extension says 20 to 30 minutes on high; Kentucky says 10 to 20 minutes at medium-to-high heat, adding that "lethal temperatures will be achieved more quickly if items are initially dry". A full, damp load takes longer to heat through, so we use the longest common figure. Loudon (2017) explains why a dryer works so well: tumbling "speeds heat penetration as items are effectively heated from all sides".
Dry-clean only clothes, shoes and bags
Many "dry-clean only" garments can still go in a dryer. According to textile experts quoted by Kentucky, most of them — cotton, wool, silk, linen, rayon, nylon — "will not be harmed provided they are dry before being placed in a clothes dryer at a moderate temperature setting". The University of Minnesota's routine is a dryer on at least medium to high for 30 minutes, then the cleaner for pressing: "Drying will kill the bugs but not clean the clothes." Dry cleaning itself also kills bed bugs (Naylor & Boase 2010), but Kentucky warns there's a risk of infesting the shop while items are tagged and sorted, so bag them and tell the cleaner. Shoes, bags and other objects can go in the dryer for 30 minutes at medium-high or the highest heat they tolerate (University of Minnesota).
Moving laundry without spreading bed bugs
The University of Minnesota's laundry steps keep bugs from dropping off on the way: sort clothes in the infested room straight into plastic bags and seal them; tip each bag into the washer (or dryer); fold the empty bag in on itself, put it into another clean bag and seal it for disposal; and carry clean laundry home in a new bag. Don't fold clean clothes on a shared laundry table you haven't checked. The EPA adds: "Remove from dryer directly into bag and fold at home." Bed bugs and their eggs can also hide in laundry hampers, so clean those too (EPA).
Travel checklist: keeping bed bugs out of your suitcase
A few minutes of checking when you arrive and a careful unpack when you get home prevent most problems. Bed bugs are found in "five-star hotels and resorts", and "how clean a place is does not determine whether bed bugs are present" (CDC).
Hotel bed bug checklist
A practical hotel bed bug checklist, put together from EPA, University of Kentucky, University of Minnesota and Nebraska Extension guidance:
- Park your luggage first. While you check the room, keep bags on a hard surface such as a desk, a closet shelf or the bathroom (Nebraska Extension).
- Check the bed. Pull back the sheets at the head of the bed and look along mattress seams and the box spring with a torch for bugs, eggs, shed skins and dark spots (Kentucky; Nebraska).
- Check the luggage rack. The EPA says to inspect luggage racks too, including the straps.
- Use the rack, not the bed or floor. Keep luggage off the bed and away from it (EPA; University of Minnesota), and keep things you don't need zipped inside the case (Kentucky).
- Seal dirty laundry. Keep worn clothes in a sealed bag, because bed bugs are drawn to the smell of worn clothing (Hentley et al. 2017; Nebraska Extension).
- Found something? Report it and ask for a room in a different part of the hotel, since infestations sometimes spread to nearby rooms (Kentucky).
How to check luggage for bed bugs after travel
How to check luggage for bed bugs after travel: assume the clothes are the risk and the suitcase is hard to inspect. Nebraska Extension advises unpacking "outside or in the garage", taking clothes straight to the dryer "on high heat for 20 to 30 minutes" before they go in the hamper, keeping shoes and bags out of bedrooms, and vacuuming or wiping luggage before storing it where nobody sleeps. The EPA's version is to "unpack directly into a washing machine", remembering that the dryer, not the wash, kills them. Bite marks can take up to 14 days to show (CDC), so keep an eye out for two weeks; the After a trip mode above dates this for you.
How this tool works
- Treat clothes & bags: the method comes from the item type and whether you have a dryer — dryer times from the University of Minnesota and Naylor & Boase (2010), wash temperature from Naylor & Boase, dry-clean guidance from Minnesota and Kentucky. The freezer time is the same 0 °F figure as our temperature calculator (Olson et al. 2013). The bag-and-wait time uses the shared no-host survival data at the temperature you enter (Johnson 1941; Polanco et al. 2011), exactly as the starvation calculator does.
- After a trip: a tick-off checklist from EPA, Kentucky and Nebraska guidance. "Watch for bites until" is your return date plus 14 days (CDC). "A stowaway's first eggs hatch by" assumes a female laid eggs the day you got home and uses the bed bug egg stage at 21 °C (Johnson 1941), the same figure as our egg hatch timer.
All times assume the heat or cold reaches the middle of the load. Overfilled dryers and thick items take longer.
Frequently asked questions
How long do bed bugs live on clothes?
As long as they can go without a blood meal: at about 21 °C adults average 64–112 days, and most of the hardiest stage are dead after about 144 days. In a cool room it can be close to a year.
How long can bed bugs live in luggage?
The same as in clothes — weeks to months at room temperature (most dead after about 144 days at 21 °C) and longer in a cold garage or loft. Store suitcases away from bedrooms (EPA).
Can bed bugs live in clothes you're wearing?
Not for long. They don't live on people; after feeding they crawl away to hide (University of Kentucky). But they can hitch a ride on clothing, shoes and bags (University of Minnesota).
How long do you have to dry clothes to kill bed bugs?
At least 30 minutes on high (University of Minnesota; Naylor & Boase 2010). Some guides give 10–30 minutes; a full or damp load needs the longer time.
Does washing clothes kill bed bugs?
A 60 °C (140 °F) wash killed every stage (Naylor & Boase 2010), but cooler washes may not (Penn State). The EPA says washing alone generally won't, so finish with a hot dryer.
Can I put dry-clean only clothes in the dryer to kill bed bugs?
Usually, if they're dry and the dryer is on a moderate setting (University of Kentucky); then take them to the cleaner. Dry cleaning also kills bed bugs.
How do I kill bed bugs in shoes?
Put them in a dryer for 30 minutes at medium-high or the highest heat they tolerate (University of Minnesota), or bag and freeze them at 0 °F.
Can bed bugs survive in a suitcase?
Yes, for weeks to months with no one to bite. They are hard to spot in luggage, so treat the contents and heat-treat or store the case away from bedrooms.
Do bed bugs like dirty clothes?
Yes. Worn clothing was significantly more attractive than clean clothing to bed bugs in a 2017 study, so keep travel laundry sealed in a bag (Hentley et al. 2017).
Should I unpack in the garage after a trip?
It helps. Nebraska Extension suggests unpacking outside or in the garage and putting clothes straight into a hot dryer for 20–30 minutes.
How long after a trip could bed bug bites appear?
Up to 14 days (CDC), so keep watching for two weeks after you get home.
Does freezing clothes kill bed bugs?
Yes: 80 hours (3.3 days) at 0 °F (−17.8 °C) in our temperature model, and at least 3.5 days is recommended for home freezers (Olson et al. 2013). Start timing when the middle is cold.
These calculators give estimates from laboratory studies, for education. Real bed bugs vary with strain, insecticide resistance, humidity and how easily they reach a host. Bed bugs are not known to spread disease (CDC), but if bites trouble you, talk to a doctor or pharmacist. For an infestation, contact a licensed pest professional or your local extension service. We give no pesticide advice.
