Bed bugs can and do hide in clothing, though they don’t live on your body or in your garments the way lice do. They treat fabric as a vehicle, crawling into seams, cuffs, and folds where they stay hidden until they reach a new location. If you’re dealing with bed bugs on your clothes, or trying to prevent it, here’s what you need to know about finding them, killing them, and keeping clean clothes safe.
How Bed Bugs End Up on Clothes
Bed bugs can’t jump or fly. They crawl, and they’re drawn to hiding spots that are dark, tight, and undisturbed. Clothing left on the floor near a bed, draped over upholstered furniture, or sitting in a laundry basket checks all those boxes. The bugs crawl into folds and seams and stay put, which is how they end up traveling between rooms, apartments, and cities.
The most common clothing-related hiding spots include luggage and suitcases, gym bags and backpacks, folded clothes in drawers or laundry baskets, and anything left near beds or couches. Clothes you wear during the day and toss on the bed at night are especially vulnerable. So are garments stored in closets adjacent to an infested wall.
Bed bugs also lay eggs on fabric. The eggs are sticky and anchor themselves to fibers in seams, making them hard to see and even harder to brush off. This is why simply shaking out your clothes isn’t enough to clear an infestation.
How to Spot Bed Bugs on Clothing
Adult bed bugs are visible to the naked eye, roughly the size of an apple seed, and reddish-brown. But the signs you’re more likely to notice on clothing are subtler. Bed bug eggs are about the size of a pinhead, pearl-white, and develop visible dark eyespots after about five days. They tend to cluster in seams and hems where fabric is folded over.
Molted skins are another telltale sign. As bed bugs grow through five life stages before adulthood, they shed their outer shell each time. These cast skins look like translucent, empty versions of the bug itself and can stick to personal belongings.
Fecal spots are the most distinctive marker. They’re small black dots (not red, because the blood has already been digested) with a smooth texture, since they’re made of dried liquid. On light-colored fabric, they’re easy to see. They often appear in clusters of ten or more in a heavily infested area, though a bug just passing through might leave only one or two. Check seams, collars, cuffs, and any place where fabric layers overlap.
Killing Bed Bugs With Heat
Heat is the most reliable way to kill bed bugs on washable clothing. The key numbers: bed bugs die after 90 minutes of constant exposure to 113°F, or within 20 minutes at 118°F. Eggs are tougher, requiring 118°F for a full 90 minutes to reach complete kill.
The simplest approach is your household dryer. A loosely filled dryer set on high will kill all life stages of bed bugs, including eggs, in 30 minutes. You don’t even need to wash the clothes first if they’re already clean. Just run them through a hot dryer cycle. If you do wash them, use hot water and follow with a high-heat dry cycle.
The “loosely filled” part matters. An overstuffed dryer won’t heat evenly, and bed bugs tucked deep inside a dense load of fabric may survive. Process smaller batches to make sure heat penetrates throughout.
Treating Delicate and Non-Washable Items
Not everything can go in a dryer on high. For dry-clean-only garments, silk, leather, or structured items like shoes, you have a few options.
Steam cleaning works if your steamer reaches at least 130°F. Hold it a few inches from the fabric and move slowly, making sure you cover every surface. Speed is the enemy here. Moving too fast means the steam doesn’t maintain contact long enough to kill bugs hiding in folds.
Freezing is another option, but it requires a deep freezer that reaches 0°F or below (a standard kitchen freezer may not get cold enough). Seal the clothing in a plastic bag and leave it in the freezer for at least 72 hours. The prolonged extreme cold kills both bugs and eggs.
For items like shoes or accessories that can’t be washed, steamed, or frozen, textile-safe bed bug sprays exist, though they should be used as a last resort and exactly according to their label instructions.
Keeping Clean Clothes Safe During an Infestation
One of the most frustrating parts of a bed bug problem is that clothes you’ve just treated can get reinfested within hours if you store them improperly. The solution is sealed containment. After drying clothes on high heat, immediately transfer them into plastic bags or airtight plastic containers and seal them shut. Don’t put treated clothes back into infested drawers or closets.
The North Carolina Department of Agriculture recommends a strict routine during an active infestation: change clothes in a room without carpeting that’s unlikely to harbor bugs, like a kitchen, bathroom, or entryway. Remove clothes from the sealed bag right before you need them. Don’t sit down or brush against upholstered furniture once you’re dressed. Keep outside shoes sealed in a container until you’re walking out the door, and wear flip-flops or slippers inside the house.
This level of discipline sounds extreme, but it serves two purposes. It keeps you from carrying bed bugs to work, friends’ homes, or public spaces. And it protects the clothes you’ve already spent time and effort decontaminating.
How Long Bed Bugs Survive on Stored Clothing
If you’ve sealed infested clothes in a bag and are wondering how long you’d need to wait for the bugs to die on their own, the answer is roughly 70 days. At room temperature, starved bed bugs at any life stage die within that window on average. Older claims that bed bugs can survive over a year without feeding came from studies conducted in unheated British homes where temperatures stayed below 40°F. In modern climate-controlled homes, those extreme survival times don’t hold up.
Sealing clothes in bags and waiting is a viable strategy for items you can’t heat-treat or freeze, but you need patience. Seventy days is the average, so building in extra time provides a safety margin.
Preventing Bed Bugs on Clothes While Traveling
Hotels are the classic transmission point. When you arrive at a room, don’t put luggage, coats, or bags on the bed. Use the luggage rack, a hard tabletop, or even the bathtub as a temporary staging area while you inspect the mattress seams and headboard for signs of bugs.
Keep clothing in sealable plastic bags inside your suitcase throughout the trip. When you return home, take all your clothes (worn and unworn) directly to the laundry in sealed bags. Wash everything in hot water and dry on high heat. Purdue University’s entomology department recommends stripping at the door and bagging the clothes you traveled in before they touch anything else in your home. Check luggage seams carefully before bringing suitcases inside.
This routine takes about 20 extra minutes after a trip. Compared to the cost and stress of a full infestation, it’s a small investment.
