Yes, bed bugs can travel from one apartment to another. They may crawl through small openings around walls and utilities, move through hallways, or hitchhike on clothing, laundry bags, luggage, furniture, and other belongings. Because nearby units can be affected, early reporting and coordinated inspection are important in an apartment building.
Quick Answer
Bed bugs can move between apartments by crawling through cracks, wall voids, gaps around pipes or electrical fixtures, doorways, and shared areas. They also spread when people carry them on clothing, luggage, furniture, or laundry. Report suspected bed bugs promptly so your unit and nearby apartments can be inspected.
Key Takeaways
- Bed bugs cannot fly or jump, but they can crawl and are excellent hitchhikers.
- In apartment buildings, they may move through wall voids, utility openings, hallways, or transported belongings.
- Bites alone cannot confirm an infestation. Look for live bugs, eggs, shed skins, dark fecal spots, and rusty stains.
- Renters should report suspected bed bugs promptly and avoid moving untreated belongings into another room.
- Effective control usually requires coordinated inspection, integrated pest management, and follow-up monitoring.
The common bed bug, Cimex lectularius, is a small, flat, wingless insect that feeds on the blood of people and other warm-blooded animals. Adults are usually reddish-brown and about 5–7 mm long, roughly the size of an apple seed. Young bed bugs, called nymphs, are smaller and lighter in color.
Bed bugs develop from eggs through five nymph stages before becoming adults. According to the U.S. Environmental Protection Agency, a female may lay about 200–500 eggs during her lifetime under favorable conditions. That reproduction rate can allow an untreated infestation to grow and spread.
Bed bugs are not known to transmit diseases to people. However, the Centers for Disease Control and Prevention states that their bites may cause itching, loss of sleep, allergic reactions, and skin infections caused by excessive scratching.
How Bed Bugs Travel
Bed bugs do not have functional wings, so they cannot fly. They also do not jump like fleas. They spread in two main ways: active crawling and passive hitchhiking.
Active Crawling
A bed bug may crawl away from its hiding place while searching for a blood meal or a new place to hide. In an apartment building, possible routes include:
- Cracks and gaps along baseboards
- Wall voids and damaged wallboard
- Openings around pipes, cables, and utility conduits
- Gaps around electrical outlets and switch plates
- Spaces beneath doors
- Shared hallways and common rooms
Bed bugs do not normally live inside plumbing or electrical wiring. Instead, they may use the unsealed spaces around pipes, conduits, outlet boxes, and other building penetrations.
Hitchhiking on Belongings
Hitchhiking is one of the most common ways bed bugs reach a new home. Their flat bodies let them hide in seams, folds, screw holes, and narrow gaps. They may be transported on:
- Luggage and overnight bags
- Folded clothing and bedding
- Laundry bags, hampers, and carts
- Mattresses and upholstered furniture
- Cardboard boxes
- Backpacks, purses, and personal belongings
Hotels, dormitories, shelters, public transportation, workplaces, theaters, and other places where many people gather can provide opportunities for a bed bug to enter a bag or piece of clothing. Finding bed bugs does not mean that a home, hotel, or person is dirty. Bed bugs are attracted to hosts and hiding places, not dirt.
Bed bugs do not need to fly or jump to spread. A small wall opening or one untreated bag can be enough to carry them into another apartment.
Can Bed Bugs Travel Between Apartments?
Yes. Bed bugs can spread from an infested apartment into neighboring units, especially when the infestation is large, treatment is delayed, or possessions are moved without being inspected or treated.
A bed bug may enter the apartment beside, above, or below an affected unit. It may crawl through structural openings or be carried through common areas on clothing, furniture, cleaning equipment, or laundry. This is why treating only one room or one apartment may fail when other units are also infested.
Current EPA guidance for landlords recommends prompt inspection after a report and evaluation of adjacent units. Depending on the building and the findings, this may include apartments on both sides and units immediately above and below.
Note: Landlord and tenant responsibilities vary by city, state, province, and country. Review your lease and local housing or public-health rules. Do not assume that one rule applies everywhere.
How Far and How Quickly Can Bed Bugs Spread?
There is no fixed timeline for apartment-to-apartment spread. Movement depends on the size and location of the infestation, access to people, the building layout, treatment activity, and how residents handle their belongings.
The CDC reports that bed bugs can travel more than 100 feet in a night, although they generally remain much closer to where people sleep. The EPA also notes that they may readily travel several feet from established hiding places to feed.
A single bed bug entering another apartment does not always create an established infestation. However, a fertilized female or several unnoticed bugs can start a new population. Prompt identification and treatment reduce that risk.
Factors That Affect Bed Bug Movement
| Factor | How It Affects Spread |
|---|---|
| Infestation size | A large population creates more competition for hiding places and blood meals, increasing the chance that bugs will disperse. |
| Building openings | Cracks, damaged walls, gaps around utilities, and open spaces beneath doors give bed bugs possible routes between rooms and units. |
| Movement of belongings | Moving untreated bedding, furniture, clothing, boxes, or bags can carry bed bugs into another apartment or common area. |
| Shared laundry | Bugs may be carried in hampers, bags, clothing, or carts if infested and treated items are not handled separately. |
| Clutter | Clutter does not cause bed bugs, but it supplies additional hiding places and makes inspection and treatment more difficult. |
| Access to hosts | Bed bugs tend to remain near sleeping or resting people but may search farther when a host is unavailable. |
| Indoor conditions | Normal heated indoor environments can support bed bug survival and reproduction. A slightly cool apartment is not protected from infestation. |
| Treatment activity | Incomplete pesticide applications or disruptive cleaning may scatter bugs without eliminating the infestation. |
Preventing Bed Bugs From Entering or Leaving an Apartment
No single method can guarantee that bed bugs will stay out. However, several practical steps can reduce the chance of introduction, improve early detection, and limit movement between units.
Seal Possible Entry Routes
- Caulk cracks along baseboards and walls where permitted.
- Seal gaps around pipes, cables, outlet boxes, and utility openings.
- Repair damaged wallboard and loose wallpaper.
- Install a door sweep to reduce movement beneath an entry door.
- Tell building management about larger structural gaps that require repair.
Sealing openings can discourage movement, but it will not eliminate bed bugs that are already present.
Use Mattress Encasements and Interceptors
Use bed-bug-resistant encasements on mattresses and box springs. A light-colored encasement removes many hiding places and makes live bugs or stains easier to notice. Check it regularly for tears.
Interceptor traps placed beneath bed and upholstered-furniture legs can help detect bugs moving toward or away from furniture. Keep the bed slightly away from the wall and prevent sheets or blankets from touching the floor.
Pro Tip: Date each interceptor check and record what you find. A simple monitoring log helps residents, property managers, and pest professionals judge whether treatment is working.
Handle Shared Laundry Carefully
If you suspect or have confirmed bed bugs, place laundry in a sealed plastic bag before carrying it through the building. Empty the bag directly into the machine when possible.
For items that can safely tolerate the treatment, the EPA recommends a household dryer at high temperature for 30 minutes. Washing alone may not kill all bed bugs. Follow each item’s care label, place dried items directly into a new clean bag or sealed container, and fold them inside your apartment rather than in the shared laundry room.
Inspect Second-Hand Items
Closely inspect used mattresses, couches, chairs, bed frames, dressers, and other furniture before bringing them indoors. Check seams, folds, screw holes, joints, undersides, and fabric edges.
A visual inspection lowers risk but cannot guarantee an item is bed-bug-free. Avoid collecting discarded mattresses or upholstered furniture from curbs, dumpsters, hallways, or unknown sources.
Take Precautions While Traveling
- Inspect the mattress seams, headboard area, and luggage rack before unpacking.
- Keep luggage off the bed and upholstered chairs.
- Store clothing in closed bags or luggage.
- Inspect bags and clothing before bringing them into the bedroom at home.
- Heat-dry suitable clothing after a suspected exposure.
Bed bugs can hide in clothing and travel gear, but special clothing does not make a person bed-bug-proof. Careful inspection, high-heat drying where suitable, and sealed handling are more useful preventive measures.
How to Identify a Bed Bug Infestation
Early identification can make an infestation easier to manage. However, bites alone cannot prove that bed bugs are present. Mosquitoes, fleas, mites, skin conditions, and allergic reactions may produce similar marks.
Physical Signs to Look For
- Live bed bugs: Flat, oval insects that may appear brown or reddish-brown
- Eggs: Tiny, pale, pearl-white objects approximately 1 mm long
- Shed skins: Pale or yellowish empty skins left as nymphs grow
- Dark spots: Bed bug fecal marks that may resemble ink dots
- Rusty or reddish stains: Marks caused by crushed bugs or digested blood
- Musty-sweet odor: A possible sign of a more established infestation, but not reliable by itself
Where to Inspect
Use a flashlight and inspect slowly around places where people sleep or rest:
- Mattress seams, labels, piping, and tufts
- Box springs and their fabric covers
- Bed frames, slats, screw holes, and headboards
- Nightstands and dresser joints
- Upholstered couches and chairs
- Baseboards and carpet edges
- Behind loose wallpaper and wall decorations
- Cracks around outlet and switch covers
Note: Do not apply liquids, powders, or pesticides inside an electrical outlet. Ask building management or a qualified pest professional to inspect safely around electrical fixtures.
If you find a suspected bug, capture it in a sealed clear container or beneath transparent tape. A pest management professional, public-health department, or university extension office may be able to confirm the identification.
What to Do If a Neighbor Has Bed Bugs
A nearby infestation does not mean your apartment is automatically infested. It does mean that early inspection and monitoring are sensible.
- Contact property management. Ask whether your apartment and the units beside, above, and below the affected unit will be inspected.
- Inspect your sleeping areas. Look for physical evidence rather than relying only on bites.
- Install interceptors. Place them beneath bed and upholstered-furniture legs to help detect activity.
- Reduce hiding places. Organize clutter without carrying loose items into another room or hallway.
- Seal accessible gaps. Caulk small openings where permitted and report building repairs to management.
- Avoid preventive pesticide spraying. Spraying without confirming an infestation may expose people or pets unnecessarily and can interfere with professional treatment.
- Continue monitoring. Check beds and interceptors regularly, especially after nearby treatment.
Dealing With Bed Bugs in an Apartment
Bed bug control in an apartment requires prompt reporting, accurate identification, careful preparation, effective treatment, and continued monitoring. Because neighboring units may be involved, trying to solve the problem secretly or treating only one piece of furniture can allow the infestation to continue.
Step 1: Report the Problem Promptly
Notify your landlord, property manager, housing office, or other responsible contact as soon as you find a suspected bed bug. Provide photographs or a captured specimen when possible.
Prompt reporting allows management to arrange identification and inspect nearby units. Delayed reporting can give the infestation more time to grow and spread.
Step 2: Avoid Spreading the Infestation
- Do not move into another bedroom or begin sleeping on the couch.
- Do not carry loose bedding, clothing, or furniture through the building.
- Keep untreated items in the infested room unless a professional tells you otherwise.
- Use sealed bags or containers when transporting items for treatment.
- Do not give away or sell items from the affected apartment.
Moving to another sleeping area may encourage hungry bed bugs to follow and establish new hiding places.
Step 3: Arrange Professional Inspection
Bed bugs can resemble bat bugs, carpet beetles, cockroach nymphs, and other insects. Correct identification prevents unnecessary or ineffective treatment.
In multi-unit housing, a qualified pest management professional should evaluate the reported apartment and determine whether nearby units or shared spaces also require inspection. The University of Minnesota Extension recommends involving the property owner or manager promptly because controlling bed bugs alone is difficult.
Step 4: Follow the Preparation Instructions
Preparation requirements vary by treatment method. Follow the pest professional’s written instructions rather than using a generic checklist that may interfere with the planned service.
Preparation may include:
- Removing items stored beneath the bed
- Vacuuming selected areas
- Heat-drying suitable clothing and bedding
- Placing treated belongings in clean sealed bags
- Moving furniture a specified distance from walls
- Providing access to baseboards, closets, and furniture
- Removing or protecting heat-sensitive items before professional heat treatment
Step 5: Use Integrated Pest Management
The EPA recommends integrated pest management, which combines appropriate chemical and nonchemical methods. Depending on the situation, a plan may include:
- Careful vacuuming
- Professional steam or heat treatment
- High-heat dryer treatment for suitable items
- Mattress and box-spring encasements
- Interceptor traps
- Sealing cracks and crevices
- EPA-registered pesticides labeled for bed bugs
- Repeated inspections and follow-up treatment
One pesticide application is rarely a complete solution. Bed bugs hide deeply, eggs may survive some methods, and resistance can reduce the effectiveness of certain insecticides.
Warning: Do not attempt whole-room heat treatment with an oven, fireplace, thermostat, hair dryer, propane heater, or unapproved space heater. Do not use outdoor pesticides indoors. Use only products registered and labeled for bed bugs, and follow every label direction. Improvised heat and pesticide treatments can cause poisoning, fire, explosion, property damage, or serious injury.
Step 6: Monitor After Treatment
Continue checking mattresses, furniture, baseboards, and interceptors after treatment. Eggs can hatch after the first service, so one day without seeing a bug does not prove that the infestation is gone.
Attend every follow-up appointment and report new evidence promptly. Do not remove encasements or monitoring devices until the pest professional advises that it is safe.
What Not to Do
- Do not rely on bug bombs. Foggers may not reach the cracks where bed bugs hide and should not be the only control method.
- Do not spray your body or bedding with pesticides unless the product label specifically allows that use.
- Do not use rubbing alcohol, gasoline, kerosene, or bleach as bed bug treatments.
- Do not raise the thermostat in an attempt to heat-treat the apartment.
- Do not move untreated belongings to another room, apartment, vehicle, or storage unit.
- Do not discard furniture carelessly. If disposal is necessary, follow management or local waste instructions, wrap the item, mark it as infested, and damage it so another person will not take it.
- Do not stop monitoring after the first treatment. Follow-up is a normal part of bed bug control.
Health Effects of Bed Bug Bites
Bed bug bites may cause no visible reaction, small itchy marks, larger swollen areas, or, rarely, a serious allergic response. Avoid scratching because broken skin may become infected.
Contact a healthcare professional if you develop signs of infection, severe swelling, extensive skin reactions, or symptoms that concern you. Seek urgent medical help for trouble breathing, facial or throat swelling, dizziness, or other signs of a serious allergic reaction.

Conclusion and Summary
Bed bugs can travel from one apartment to another by crawling through small building openings or hitchhiking on clothing, furniture, luggage, laundry, and other belongings. An infestation in one unit may therefore affect apartments beside, above, or below it.
The most effective response is early, coordinated action. Report suspected bed bugs promptly, avoid moving untreated items, look for physical evidence, and ask whether adjacent units will be inspected. Professional treatment should use an integrated plan rather than relying on one spray or a single cleaning session.
Sealing accessible gaps, handling shared laundry carefully, using encasements and interceptors, and monitoring after treatment can reduce the risk of continued spread. Bed bugs are difficult to eliminate, but careful preparation and cooperation between residents, management, and pest professionals can bring an infestation under control.
Frequently Asked Questions
What are bed bugs?
Bed bugs are small, flat, wingless insects that feed on the blood of people and animals. Adults are usually reddish-brown and about 5–7 mm long. They often hide near beds, couches, and other places where people sleep or rest.
How do bed bugs travel from one apartment to another?
They may crawl through cracks, wall voids, gaps around pipes or electrical fixtures, doorways, and hallways. They can also hitchhike on clothing, bedding, furniture, luggage, laundry bags, boxes, and other belongings.
Can bed bugs travel through walls?
Bed bugs can move through wall voids and small openings around baseboards, utility conduits, pipes, electrical boxes, and damaged wall surfaces. They do not chew through a solid wall, but they can use existing gaps as pathways.
Do bed bugs infest multiple apartments in a building?
Yes. An infestation may involve several units, especially when it has existed for a long time or residents have moved untreated possessions. This is why pest professionals often inspect apartments beside, above, and below a confirmed infestation.
How can I prevent bed bugs from entering my apartment?
Seal accessible cracks, install a door sweep, inspect second-hand furniture, handle shared laundry in sealed bags, check travel gear, use mattress encasements, and monitor with interceptor traps. These steps reduce risk but cannot guarantee complete protection.
Should I move to another room if I find bed bugs?
Usually, no. Sleeping in another room may cause hungry bed bugs to follow you and create additional hiding places. Keep possessions contained and follow the instructions provided by the property manager or pest professional.
Does washing clothing kill bed bugs?
Washing alone may not kill all bed bugs. For suitable items, the EPA recommends drying at high temperature for 30 minutes. Follow fabric-care instructions and place treated items directly into clean sealed bags or containers.
Can I confirm bed bugs by looking at bites?
No. Bite reactions vary and may resemble marks caused by other insects or skin conditions. Confirm the problem by looking for live bugs, eggs, shed skins, dark fecal spots, and rusty stains, or have a professional identify a captured specimen.
