How Do You Get Bed Bugs?

The Truth About How You Get Bed Bugs

The most common misconception about bed bugs is that they're caused by poor hygiene or dirty living conditions. This is completely false. Bed bugs are blood-feeding parasites that are attracted to warmth, carbon dioxide, and the presence of a sleeping human host—not dirt, food scraps, or clutter. A spotless home in a high-end neighborhood is just as likely to get bed bugs as a cluttered apartment.

So how do you get bed bugs in the first place? The answer is almost always the same: they hitchhike. Bed bugs don't fly, don't jump, and don't live outdoors. They travel from place to place by clinging to luggage, clothing, furniture, and personal belongings. Every bed bug infestation starts with an introduction—a single bug or a small group that catches a ride into your home from somewhere else.

Understanding these introduction pathways is critical, because once bed bugs establish themselves in your home, they reproduce rapidly. A single mated female can produce 200–500 eggs over her lifetime, turning a small introduction into a full infestation within weeks.

Travel and Hotels: The #1 Way People Get Bed Bugs

Hotels, motels, Airbnbs, and vacation rentals are the single most common source of bed bug introductions into homes. High guest turnover means bed bugs are constantly being introduced to these environments, and they spread to new guests through infested mattresses, headboards, nightstands, and upholstered furniture.

Here's how it happens: you check into a hotel room where a previous guest unknowingly left behind bed bugs. While you sleep, bed bugs feed on you and then retreat to their hiding spots. When you pack up to leave, bed bugs crawl into your open suitcase, tuck themselves into the folds of your clothing, or hide in the seams of your travel bag. You carry them home without realizing it, unpack your belongings, and the bed bugs settle into your bedroom.

How to Protect Yourself While Traveling

• Inspect the room before unpacking: Pull back bedsheets and check mattress seams, headboard crevices, and nightstand drawers for dark spots, shed skins, or live bugs.
• Keep luggage off the floor and bed: Use the metal luggage rack or store your suitcase in the bathroom (smooth tile surfaces offer no hiding spots for bed bugs).
• Never place clothing in hotel drawers: Keep everything in your sealed suitcase or hanging in the closet away from the wall.
• Launder everything immediately upon return: Wash and dry all travel clothing on the highest heat setting—bed bugs and eggs die at 120°F+ sustained heat.
• Inspect your luggage outside: Before bringing your suitcase inside after a trip, inspect it in the garage or on the porch. Check seams, pockets, and zippers.

Used Furniture and Secondhand Items

Bringing used furniture into your home is one of the most common—and most preventable—ways people get bed bugs. Bed bugs hide deep inside mattress seams, couch cushion folds, bed frame joints, dresser drawers, and even behind the fabric backing of upholstered furniture. A casual visual inspection rarely catches them because they're experts at hiding in cracks as thin as a credit card.

High-Risk Items to Inspect or Avoid

• Mattresses and box springs: The highest-risk secondhand item. Inspect every seam, tuft, label, and corner. Look for dark fecal spots, shed skins, and eggs. When in doubt, don't bring it home.
• Upholstered couches and chairs: Bed bugs nest in cushion seams, underneath fabric, and inside the frame. Flip the furniture over and inspect the underside carefully.
• Bed frames and headboards: Check joints, screw holes, and any cracks or crevices. Wooden bed frames with rough surfaces are especially popular harborage sites.
• Dressers and nightstands: Pull out drawers completely and inspect the tracks, back panels, and any cracks in the wood. Bed bugs don't just live in beds.
• Clothing and textiles from thrift stores: While lower risk than furniture, secondhand clothing should be laundered on high heat before being stored in your closet.

The safest approach to used furniture is to avoid upholstered items entirely unless you can inspect them thoroughly or have them professionally treated before bringing them inside.

Visitors, Guests, and Social Contact

You don't have to travel or buy used furniture to get bed bugs. Sometimes they arrive on the belongings of people who visit your home—or you pick them up by visiting someone else's infested space. This is an uncomfortable topic, but it's one of the most common introduction pathways.

How Social Contact Spreads Bed Bugs

• Overnight guests: A friend or family member with an undetected infestation at their home can bring bed bugs in their overnight bag, clothing, or personal items. The bugs transfer to your guest room and establish themselves.
• Visiting infested homes: Sitting on someone's infested couch, hanging your coat in their closet, or setting your bag on their floor can transfer bed bugs to your belongings. You won't know until they've had time to establish in your home.
• Children's sleepovers: Kids bring sleeping bags, pillows, and stuffed animals between homes—all potential carriers. A child's sleepover at an infested home can bring bed bugs back on their belongings.
• Service workers and home visits: Anyone entering your home with bags, equipment, or clothing can potentially introduce bed bugs. This includes movers, repair workers, and home healthcare providers.

This doesn't mean you should stop having guests or avoid visiting friends. It means being aware that bed bugs travel on people and belongings, and taking simple precautions like inspecting guest bedding after visitors leave and laundering travel items on high heat.

Apartments, Condos, and Shared Housing

If you live in a multi-unit building, you can get bed bugs through no fault of your own. Bed bugs travel between units through shared wall voids, electrical conduits, plumbing chases, and under-door gaps. A neighbor's infestation can become yours within weeks as bed bugs migrate through the building infrastructure.

This is one of the most frustrating ways to get bed bugs because prevention is largely out of your control. Even if you keep your unit spotless and take every precaution, bed bugs from an adjacent unit can enter through pathways you can't see or seal.

Why Multi-Unit Buildings Are High Risk

• Shared walls and infrastructure: Bed bugs crawl through wall cavities, following pipes and wires between units. A wall separating two apartments is no barrier to a bed bug.
• Tenant turnover: Each new tenant who moves in could unknowingly bring bed bugs. Frequent turnover means constant introduction opportunities.
• Chemical treatment backfires: When one unit is treated with pesticides, bed bugs sense the chemicals and flee into adjacent untreated units—spreading the infestation rather than eliminating it.
• Shared laundry rooms: Communal laundry facilities create transfer opportunities. Bed bugs can move from one person's hamper or clothing to another's.

If you live in an apartment and suspect bed bugs, report it to your landlord or property manager immediately. Under Washington RCW 59.18, landlords are responsible for maintaining habitable conditions, which includes pest control. Professional heat treatment is the best option for apartments because it kills bed bugs in place without causing them to flee to neighboring units.

How to Prevent Getting Bed Bugs

While no prevention method is 100% foolproof, these proven strategies significantly reduce your risk of getting bed bugs:

At Home

• Use mattress and box spring encasements: Zippered encasements trap any existing bed bugs inside (where they eventually starve) and create a smooth surface that makes new introductions easier to spot.
• Install ClimbUp interceptors under bed legs: These passive monitors trap bed bugs attempting to climb up to your bed, providing early warning of any introduction.
• Reduce clutter around sleeping areas: While clutter doesn't cause bed bugs, it provides more hiding spots and makes detection harder. Keep the area around your bed clear.
• Inspect regularly: Check mattress seams, headboard crevices, and bed frame joints monthly. Look for dark fecal spots, shed skins, and tiny white eggs.

While Traveling

• Inspect every room before settling in: Check the mattress, headboard, and nightstand in every hotel, Airbnb, or vacation rental—even high-end properties.
• Keep luggage elevated and sealed: Use hard-sided luggage when possible. Store it on luggage racks or in the bathroom, never on the bed or floor.
• Launder all travel clothing on high heat: Run everything through the dryer on the highest setting for at least 30 minutes immediately upon returning home.

When Buying Used Items

• Thoroughly inspect all secondhand furniture: Check every seam, joint, crack, and crevice. If you can't inspect it thoroughly, don't bring it home.
• Avoid curbside furniture: Items left on the curb are often discarded because of pest issues. The savings aren't worth the risk of a bed bug infestation.
• Launder all secondhand clothing: Wash and dry on high heat before storing in your closet or dresser.
