Bed bugs spread almost exclusively by hitchhiking on people’s belongings. They crawl into luggage, clothing, furniture, and other personal items, then travel to new locations when those items move. They don’t jump, fly, or live on your body the way fleas or lice do. Understanding exactly how they get around helps you avoid bringing them home.
Hitchhiking Is the Primary Method
Bed bugs are crawlers, not jumpers or fliers. They lack wings entirely, and their legs aren’t built for leaping. They move at a pace of about one to three feet per minute, which means they aren’t chasing you down a hallway. Instead, they rely on proximity and opportunity. When your suitcase sits on an infested hotel carpet or your coat rests on a chair where bed bugs are hiding, the insects crawl aboard and ride along to your next destination.
This hitchhiking behavior is what makes bed bugs so effective at spreading globally. A single bug tucked into a luggage seam can cross an ocean in hours. They don’t need to be near a host during the trip, either. Adult bed bugs survive an average of about five months without a blood meal, and under certain conditions they can last over 400 days. That means a bed bug hiding in a stored suitcase or a piece of furniture in a warehouse is still alive and ready to infest a new space months later.
Common Ways They Enter Your Home
Travel is the most well-known route, but it’s far from the only one. Here are the most common ways bed bugs end up in a new space:
- Luggage and bags. Hotel rooms, Airbnbs, and even airports expose your bags to potential infestation. Bed bugs hide in seams, zippers, and pockets.
- Used furniture. Sofas, chairs, mattresses, dressers, and headboards are high-risk items. After beds, stuffed sofas and chairs are the most common places bed bugs hide. They tuck into upholstery seams, tiny cracks in wood, and the undersides of drawers.
- Clothing. Worn or packed clothing left near an infested area can pick up bugs or eggs. Shared laundry facilities in apartment buildings are another potential transfer point.
- Shared spaces. Offices, movie theaters, public transit, and waiting rooms with upholstered seating can all harbor bed bugs. If you sit in an infested seat, a bug can crawl onto your clothing or bag.
- Neighboring apartments. In multi-unit housing, bed bugs crawl through wall voids, along pipes, and through electrical outlets to reach adjacent units. This is active migration rather than hitchhiking, and it’s one of the few ways they spread under their own power.
How They Find You Once Inside
Once bed bugs arrive in a new location, they need to find a host. Carbon dioxide is their primary attractant. Every time you exhale, you release CO2, and bed bugs follow that trail to locate you while you sleep. They also detect body heat and certain chemical signals from skin. This is why infestations center around beds and sleeping areas: you’re stationary for hours, producing a steady stream of exactly the signals they’re tracking.
They don’t nest on your body. After feeding for a few minutes, they retreat to nearby hiding spots like mattress seams, bed frame joints, and cracks in headboards. During the day, they stay hidden, which is part of why infestations grow undetected for weeks before anyone notices bites or spots on the sheets.
Eggs Make Them Harder to Stop
A single pregnant female can start an entire infestation. Female bed bugs lay eggs in clusters, cementing them to surfaces with a glue-like protein that bonds firmly to fabric, wood, and other materials. These eggs are roughly the size of a pinhead and nearly translucent, making them extremely difficult to spot on light-colored surfaces. The adhesive is strong enough that casual wiping or shaking won’t dislodge them, which is why eggs hidden in luggage linings or furniture seams survive the trip to a new location so effectively.
Eggs hatch in about six to ten days under normal room temperatures. A single female can produce hundreds of eggs in her lifetime, so even one overlooked egg cluster in a used dresser or a travel bag can seed a full infestation within weeks.
How to Reduce Your Risk
When traveling, keep your luggage off the floor and away from the bed. Use the metal luggage rack if one is available, and inspect the mattress seams and headboard of your hotel room before settling in. When you return home, vacuum your suitcases and bags thoroughly before bringing them inside. Tossing your travel clothes into a dryer on high heat for 30 minutes kills all life stages of bed bugs, including eggs.
If you’re buying used furniture, inspect it carefully before bringing it into your home. Remove cushions and check along decorative edges and seams. Turn the piece over and examine the underside. Look for small dark spots (fecal stains), shed skins, or the bugs themselves, which are flat, oval, and roughly the size of an apple seed. Dressers and nightstands need the same treatment: open every drawer, check the joints, and flip the piece to inspect underneath. Metal bed frames are less attractive to bed bugs than wood but still need inspection.
In apartment buildings, sealing cracks around baseboards, outlets, and pipes can slow the spread from neighboring units. If you know a nearby unit is infested, proactive monitoring with interceptor traps under your bed legs can catch bugs early before they establish themselves.
