Bed bugs spread by hitchhiking in luggage, used furniture, mattresses, bedding, clothing and bags, then crawling out to hide near where people sleep. In apartments and hotels they also travel between units through cracks in walls, along pipes and wiring and behind outlets. They aren’t contagious: they don’t live on people, can’t fly or jump, and aren’t known to spread disease.

Are Bed Bugs Contagious?
No. Unlike head lice and the mites that cause scabies, bed bugs don’t live on the body. They have no claws or hooks to grip hair or skin, so they feed for a few minutes and then crawl back to a hiding place. You can’t catch bed bugs by touching or hugging someone, and the bites themselves aren’t contagious.
A bed bug can ride briefly in a fold of clothing, on a bag or in a shoe, so people do occasionally carry one from an infested place into a new one.
How Bed Bugs Spread From Place to Place
- Luggage: seams and folds of suitcases picked up in hotels, hostels and on public transport.
- Used furniture and mattresses: one of the most common ways bed bugs enter homes. Be careful with curbside finds.
- Clothing and bedding: worn clothes left on an infested bed or floor.
- Bags and boxes: backpacks, purses, laptop cases and moving or packing boxes.
- Shared spaces: wheelchairs, shoes and items in shelters, dorms, nursing homes and offices.
How Bed Bugs Spread From Room to Room
Bed bugs crawl and can cover more than 100 feet in a night, though most stay within about 8 feet of a bed or couch. As numbers grow, or after treatment disturbs them, they move into nearby rooms along baseboards and through gaps under doors. Carrying bedding, pillows or clothes from an infested room to another spreads them faster.
How Bed Bugs Spread Between Apartments
In multi-unit buildings, bed bugs move through cracks in shared walls, floors and ceilings, along pipes and electrical wiring, and through utility openings, outlets and switch plates. They often spread to neighbors when an apartment sits empty after the tenant moves out or when infested furniture is dragged through halls. Building-wide inspection works better than treating one unit at a time.
How Fast Do Bed Bugs Spread?
Bed bugs reproduce fairly slowly compared with many insects, which is why an infestation can go unnoticed for weeks:
| Step | Typical timing |
|---|---|
| Eggs laid | 1 to several a day per female; about 200 to 500 in a lifetime |
| Eggs hatch | About 6 to 17 days, usually about a week at room temperature |
| Egg to adult | About a month at 70 to 80°F, longer in cooler rooms |
| Adult lifespan | About 10 months, sometimes longer |
| Survival without feeding | 1 to 4 months in a heated home; a year or more in cool conditions |
A few bugs brought home in a suitcase can become a noticeable infestation within a few months. Because they survive long without food, an empty room or apartment doesn’t starve them out quickly.
Can Bed Bugs Fly or Jump?
No. Bed bugs have only tiny wing pads and can’t fly, and they don’t jump like fleas. They spread by crawling and by riding in belongings. More in can bed bugs fly or travel.
Do Bed Bugs Spread Disease?
Bed bugs are not known to spread disease to people. Researchers have found disease organisms on bed bugs, but there is no evidence they pass them on through bites. The real health effects are itchy bites, skin infections from scratching, and anxiety and sleepless nights; see can bed bugs make you sick.
How to Stop Bed Bugs Spreading
When traveling
- Check hotel mattress seams and headboards before unpacking.
- Keep luggage on a rack or in the bathroom, off the bed and floor.
- Seal dirty clothes in plastic bags.
- At home, unpack outside the bedroom and run clothes through a hot dryer for 30 minutes.
At home
- Inspect used furniture and mattresses before bringing them in, or skip them.
- Use zippered encasements on mattresses and box springs.
- Put interceptor cups under bed legs to catch bugs early.
- Reduce clutter, especially under the bed.
- If you find bed bugs, don’t move to another room to sleep; that spreads them. Start treatment instead.
In apartments
- Tell your landlord or building manager quickly so neighboring units can be inspected.
- Seal cracks around baseboards, pipes and outlets.
- Bag and label infested furniture before carrying it out, so others don’t pick it up.
