If you live in a flat, converted house or shared building, you may wonder: can bed bugs come from neighbors?
The answer is yes. Bed bugs can sometimes move between neighboring properties, especially where flats share walls, pipework, electrical routes or other structural gaps.
However, neighboring flats are not the only source of an infestation. Bed bugs can also enter a property through luggage, furniture, clothing and personal belongings.
In apartment buildings, though, an infestation in one unit may occasionally spread into adjoining rooms or neighboring flats if the problem becomes established.
Understanding how this happens can help you act early and reduce the risk of bed bugs spreading further through the building.
How Can Bed Bugs Spread Between Flats?
Bed bugs cannot fly or jump. They move by crawling and can squeeze through very small gaps.
In connected properties, they may travel through:
- Cracks in walls
- Gaps around pipes
- Floor and ceiling voids
- Openings around skirting boards
- Gaps around electrical fittings
- Spaces beneath doors
- Shared hallways
- Wall cavities
If one flat has a significant infestation, bed bugs may gradually move away from their original hiding places and enter nearby areas.
This does not mean every infestation will automatically spread to neighboring flats. However, adjoining properties may need to be considered when activity keeps returning or appears in more than one part of a building.
Which Properties Have a Higher Risk?
Bed bug movement between neighboring properties may be more relevant in buildings where several households live close together.
This can include:
- Blocks of flats
- Converted houses
- HMOs
- Student accommodation
- Hostels
- Shared housing
- Serviced apartments
- Buildings with shared pipework
- Properties with connected wall cavities
In East London, many homes are flats, converted properties and shared accommodation. This makes it important to consider the wider building when dealing with a persistent infestation.
Can Bed Bugs Travel Through Walls?
Bed bugs may move through gaps and openings around walls rather than travelling directly through solid walls.
Possible routes include:
- Cracks around skirting boards
- Gaps where pipes enter walls
- Electrical fittings
- Wall voids
- Loose flooring
- Gaps around door frames
Their flat bodies allow them to hide in narrow spaces that are difficult to see during a quick inspection.
If bed bugs are repeatedly found near a shared wall, adjoining areas may need closer inspection.
Can Bed Bugs Move Through Pipes?
They may move through gaps around pipework.
Bathrooms, kitchens and heating pipes can sometimes create openings between neighboring rooms or flats.
The insects are not living inside the pipes themselves. Instead, they may use the gaps around pipework as a route between connected areas.
Sealing obvious gaps may help reduce potential movement, but this should not replace proper treatment where an infestation is already present.
Can Bed Bugs Spread Through Shared Hallways?
Bed bugs are more likely to spread through belongings than by walking long distances through a hallway.
However, shared areas can still contribute to the spread of an infestation.
For example, problems may occur when:
- Infested furniture is left in a corridor
- Untreated mattresses are moved through shared areas
- Bags or clothing are placed near infested belongings
- Furniture is moved between flats
- Infested laundry is transported without being sealed
For this reason, avoid leaving potentially infested furniture or bedding in communal spaces.
Can Bed Bugs Come From the Flat Above or Below?
Yes, it is possible.
Bed bugs may move between floors where structural gaps, pipework or service routes connect different parts of the building.
However, finding bed bugs in your flat does not automatically prove that they came from the property above or below.
They may also have been introduced through:
- Travel luggage
- Second-hand furniture
- Visitors’ belongings
- Clothing
- Moving home
- Furnished rental accommodation
A proper inspection is usually needed before the likely source can be assessed.
What Should You Do If Your Neighbor Has Bed Bugs?
If you know that a neighboring flat has bed bugs, there is no need to panic.
However, it is sensible to monitor your property carefully.
Check areas such as:
- Mattress seams
- Bed frames
- Headboards
- Bedside furniture
- Skirting boards
- Carpet edges
- Sofas
- Cracks near shared walls
Avoid bringing furniture, bedding or bags from the affected property into your home.
If you live in rented or managed accommodation, report the situation to your landlord or property manager.
Depending on the building layout, neighboring flats may need inspection.
What Signs Should You Look For?
If you are unsure whether you have an infestation, learn how to detect bed bugs by checking the most common hiding areas and physical signs.
These can include:
- Live reddish-brown insects
- Dark faecal spots
- Blood marks on bedding
- Pale eggs or eggshells
- Shed skins
- Activity around mattress seams
- Unexplained bites
Bites alone cannot confirm a bed bug infestation because other insects and skin conditions may cause similar marks.
Physical evidence is more useful when assessing whether bed bugs are present.
Where Should You Check First?
Start with areas closest to where you sleep.
Mattress Seams
Check mattress piping, labels, corners and stitched seams.
Bed Frame and Headboard
Inspect joints, screw holes, slats and cracks.
Divan Base
Look underneath the fabric, inside drawers and around storage compartments.
Skirting Boards
Pay particular attention to areas near the bed and shared walls.
Bedside Furniture
Inspect drawer joints, back panels, screw holes and undersides.
Bed bugs can also hide in sofas, upholstered chairs and nearby furniture.
Should You Move to Another Room?
Avoid moving into another bedroom if you suspect bed bugs.
Changing sleeping areas can sometimes encourage insects to spread into previously unaffected rooms.
You should also avoid moving:
- Bedding
- Mattresses
- Clothing
- Furniture
- Storage boxes
between rooms unless they have been properly treated or contained.
Keeping the infestation limited to one area can make professional treatment easier.
Should You Tell Your Landlord or Property Manager?
Yes, particularly if you live in a rented flat, HMO or managed building.
A landlord or property manager may need to consider whether:
- Adjoining flats should be inspected
- Shared areas are affected
- Another unit has reported bed bugs
- Structural gaps are contributing to movement
- Treatment needs to be coordinated
Early reporting may help prevent a small problem from becoming more widespread.
What If Bed Bugs Keep Returning After Treatment?
Repeated activity does not always mean treatment has failed.
Possible reasons include:
- Hidden harborages were missed
- Eggs have hatched
- Infested belongings were moved
- Another room is affected
- An adjoining flat may have activity
- Follow-up treatment was not completed
If bed bugs return, report the activity rather than repeatedly applying different DIY products.
A wider inspection may be needed to determine whether the infestation involves more than one room or property.
Can DIY Sprays Stop Bed Bugs Moving Between Flats?
Household sprays may kill some exposed insects, but they may not reach bed bugs hidden inside cracks, furniture or structural gaps.
DIY treatment can also become less effective when:
- Only visible insects are treated
- Adjoining rooms are ignored
- Furniture is moved before treatment
- Eggs remain hidden
- Several insecticides are mixed
- Treatment stops when activity temporarily decreases
For persistent infestations, a structured inspection and treatment plan is usually more appropriate.

How to Reduce the Risk of Bed Bugs Spreading Between Flats
You cannot completely prevent bed bugs from entering a property, but several precautions may reduce the risk.

- Seal obvious gaps around pipes and skirting boards
- Inspect second-hand furniture before bringing it indoors
