How Do You Get Bed Bugs? 6 Common Causes & Prevention
Bed bugs do not appear out of thin air. They hitchhike. Here are the 6 most common ways they enter Washington homes — and what you can do to stop them.
In This Article
One of the most common questions we hear from homeowners is: how did I get bed bugs? There is a persistent misconception that bed bugs are caused by poor hygiene or unsanitary living conditions. That is not how it works.
Bed bugs are hitchhikers. They travel from place to place by hiding in luggage, clothing, furniture, and personal items. An infestation can start with a single pregnant female finding her way into your home. Understanding how bed bugs spread is the first step toward preventing them — and knowing what to do if they arrive.
Understanding Bed Bugs: The Basics
Bed bugs (Cimex lectularius) are small, flat, reddish-brown insects about the size of an apple seed. They are wingless and cannot fly or jump. They crawl at roughly 3 to 4 feet per minute and are primarily active at night.
Unlike cockroaches, which are attracted to food debris and unsanitary conditions, bed bugs are attracted to only one thing: blood. They feed exclusively on the blood of warm-blooded mammals, with a strong preference for humans. They inject an anesthetic when they bite, allowing them to feed for 5 to 10 minutes without waking their host.
Bed bugs are about the size of an apple seed — small enough to hide in cracks as narrow as a credit card
Bed bugs are expert hiders. While they prefer to nest near sleeping hosts (mattresses, box springs, headboards), they will hide in any crack or crevice they can find: baseboards, electrical outlets, picture frames, dresser drawers, couch cushions, and even behind wallpaper. In severe infestations, they spread far beyond the bedroom.
Key Fact: A well-fed bed bug at room temperature can survive 2 to 3 months without a blood meal. In cooler temperatures, their metabolism slows and they can survive even longer. This is why bed bugs can persist in vacant apartments and stored furniture.
6 Most Common Sources of Bed Bug Infestations
Bed bugs do not teleport into your home. Every infestation has a source. Here are the six most common ways bed bugs enter Washington homes.
1 Hotels and Temporary Lodging
Hotels, motels, vacation rentals, and hostels are among the most common sources of bed bug infestations. High guest turnover means constant opportunities for bed bugs to be introduced by travelers from anywhere in the world.
Once established in a hotel room, bed bugs spread quickly through luggage, clothing, and housekeeping equipment. A single trip can bring hitchhikers home in your suitcase, backpack, or jacket.
Luggage is one of the most common vehicles for bed bug hitchhiking between locations
2 Used Furniture and Mattresses
Secondhand furniture is one of the top sources of bed bug introductions. Mattresses, couches, chairs, bed frames, dressers, and nightstands can all harbor hidden bed bugs and eggs. Curbside furniture, online marketplace finds, and thrift store purchases all carry risk.
Bed bugs hide deep in seams, joints, and crevices where they are nearly impossible to detect without a thorough inspection. Even wooden furniture can harbor bed bugs in screw holes and joint gaps.
3 Clothing and Personal Items
Bed bugs readily hide in clothing, backpacks, purses, and other personal items. Thrift store clothing, borrowed items, and even new clothes from stores with infestations can introduce bed bugs to your home.
Any fabric item that has been in an infested environment is a potential carrier. This includes stuffed animals, pillows, blankets, and fabric bags.
4 Neighboring Units in Multi-Family Housing
In apartment buildings, condominiums, and dormitories, bed bugs frequently travel between units through wall voids, shared plumbing, electrical conduits, and under doors. You can do everything right and still get bed bugs from a neighbor's infestation.
King County's high population density and prevalence of multi-unit housing make this a particularly common source of infestations in our service area.

5 Public Spaces and Transportation
Any place where people congregate is a potential transfer point for bed bugs. Public transportation (buses, trains, rideshares), offices, schools, libraries, theaters, healthcare facilities, and daycares can all facilitate bed bug hitchhiking.
A bed bug does not need to bite you in a public space — it simply needs to crawl from one person's belongings to yours. Placing a coat or bag next to an infested item is enough.
6 Non-Fabric Items and Packages
Bed bugs do not limit themselves to fabric. Books, electronics, alarm clocks, picture frames, and any item stored in an infested environment can carry bed bugs. Even packages and deliveries that were stored in infested warehouses pose a small risk.
The Bottom Line: Getting bed bugs is not a reflection of how clean your home is. Bed bugs are attracted to blood, not dirt. Five-star hotels, luxury apartments, and spotless homes all get bed bug infestations. What matters is how quickly you identify the problem and respond.

While no prevention method is foolproof, these practical steps significantly reduce your risk of a bed bug infestation.
Inspect Hotel Rooms
Before unpacking, check mattress seams, headboards, and luggage racks with a flashlight. Keep luggage on hard surfaces, not beds or carpet.
Launder Travel Clothes
Wash and dry all clothing on high heat immediately after returning from travel. Inspect luggage in a garage or bathtub before storing it.
Inspect Used Items
Thoroughly check all secondhand furniture, clothing, and household items before bringing them inside. Look for live bugs, dark spots, eggs, and shed skins.
Use Mattress Encasements
Quality, tear-resistant encasements on mattresses and box springs eliminate hiding spots and make regular inspections easier.
Reduce Clutter
Bed bugs are not attracted to clutter, but clutter gives them more places to hide. A tidy home makes it easier to spot warning signs early.
Vacuum Regularly
Vacuum mattress seams, baseboards, furniture crevices, and carpet edges routinely. Dispose of vacuum contents in a sealed bag immediately after.
Apartment Dwellers: If you live in a multi-unit building, communicate with your property manager about any suspected infestations. Early reporting helps prevent building-wide spread. Bed bugs travel through shared walls, so one unit's problem can quickly become everyone's problem.
Early Warning Signs of Bed Bugs
Catching an infestation early is critical. The sooner you identify bed bugs, the smaller the problem and the easier it is to treat. Watch for these warning signs:
- Dark fecal spots on sheets, mattress seams, pillowcases, and baseboards (small, dark brown or black spots)
- Tiny blood stains on bedding from crushed bugs after feeding
- Shed exoskeletons (translucent, shell-like casings) near hiding spots
- Bed bug eggs (tiny, white, about 1mm) in mattress seams and furniture joints
- A sweet, musty odor in heavily infested areas
- Bites in clusters or lines on exposed skin, though not everyone reacts visibly
Dark fecal spots on sheets and mattresses are one of the most reliable early signs of bed bugs
Do Not Rely on Bites Alone: Up to 30% of people show no visible reaction to bed bug bites. If you suspect bed bugs, look for physical evidence (fecal spots, shed skins, eggs) rather than waiting for bite marks to appear.
What to Do If You Find Bed Bugs
If you discover signs of bed bugs, the most important thing is to act quickly and avoid common mistakes that make the problem worse:
- Do not panic. Bed bug infestations are treatable. Rash decisions (throwing out furniture, using bug bombs) often spread the infestation to new areas.
- Do not use store-bought sprays or foggers. OTC products are largely ineffective due to widespread pesticide resistance and can scatter bed bugs into adjacent rooms or apartments.
- Contact a professional. A licensed bed bug specialist can confirm the infestation and recommend the most effective treatment for your situation.
- Avoid moving items between rooms. This can spread bed bugs to previously uninfested areas of your home.
- Continue sleeping in your bed. Moving to the couch or a different room encourages bed bugs to follow you, spreading the infestation further.

Frequently Asked Questions
Can you get bed bugs from a clean home?
Yes. Bed bugs are attracted to blood and CO2, not dirt or filth. Spotlessly clean homes, five-star hotels, and luxury apartments can all have infestations. Cleanliness does not prevent bed bugs, though it makes them easier to spot during inspections.
How do bed bugs spread from room to room?
Bed bugs crawl through wall voids, shared plumbing, electrical conduits, and under doors. In apartments, they travel between adjacent units through shared walls. They also spread by hitchhiking on clothing, bags, and furniture moved between rooms.
Can you get bed bugs from hotel rooms?
Hotels are one of the most common sources of bed bug infestations. High guest turnover creates constant introduction opportunities. Bed bugs hitchhike home in luggage, clothing, and personal items. Always inspect hotel rooms before unpacking.
Can bed bugs come from used furniture?
Yes. Used furniture is one of the most common sources. Bed bugs hide in mattresses, couches, chairs, bed frames, and dressers. Always inspect secondhand items thoroughly before bringing them into your home.
How can I prevent bed bugs when traveling?
Inspect hotel rooms before unpacking — check mattress seams, headboards, and luggage racks. Keep luggage on hard surfaces away from beds. Upon returning, wash and dry all clothing on high heat. Inspect luggage in a garage or bathtub before storing.
What are the first signs of a bed bug infestation?
Early signs include dark fecal spots on sheets and mattresses, tiny blood stains on bedding, shed exoskeletons, a sweet musty odor, and bites appearing in clusters or lines. Not everyone reacts visibly to bites, so physical evidence is more reliable.
