Many people assume bed bugs appear because a property is dirty or poorly maintained. However, this is not usually the case.
Understanding what causes bed bugs is important because these insects can enter almost any home, flat, hotel or commercial property.
Bed bugs are excellent hitchhikers. They are often carried from one place to another through luggage, furniture, clothing and personal belongings.
Once inside a property, they usually settle close to places where people sleep or spend long periods sitting. If they are not detected early, they can gradually spread into furniture, adjoining rooms and neighboring properties.
This guide explains how bed bug infestations start, how they spread and what you can do to reduce the risk.
What Causes Bed Bugs in a Home?
Bed bugs are not normally caused by poor cleaning.
Instead, they are usually brought inside by accident.
Common ways bed bugs enter homes include:
- Luggage after travelling
- Second-hand furniture
- Used mattresses and bed frames
- Clothing and bedding
- Guests carrying infested belongings
- Furniture deliveries
- Shared laundry facilities
- Movement between neighboring flats
- Hotel and hostel stays
- Stored boxes and personal belongings
Even a clean and well-maintained property can develop a bed bug infestation if insects or eggs are introduced accidentally.
How Do Bed Bugs Spread?
Once bed bugs enter a property, they usually stay close to a reliable food source.
Because they feed on people, they are often found around beds, sofas and other areas where people remain still for long periods.
As an infestation becomes established, bed bugs may spread into additional rooms.
They can move through:
- Cracks in walls
- Gaps around skirting boards
- Pipework
- Electrical fittings
- Wall cavities
- Furniture
- Clothing
- Bedding
- Luggage
- Boxes and stored belongings
This is why moving furniture or personal items from an affected room into another area can make the problem worse.
Can Bed Bugs Spread Between Flats?
Yes.
Flats, HMOs, shared accommodation and converted houses can be more vulnerable because neighboring properties may share walls, pipework and structural gaps.
Bed bugs may move between units through:
- Cracks around walls and floors
- Pipework
- Electrical routes
- Shared corridors
- Laundry areas
- Furniture movement
If bed bugs keep appearing in a flat after treatment, adjoining rooms or neighboring units may also need to be checked.
Can Bed Bugs Come From Hotels?
Yes. Hotels and other accommodation are common places where bed bugs may be picked up.
Bed bugs can hide in:
- Mattress seams
- Bed frames
- Headboards
- Upholstered furniture
- Luggage racks
- Curtains
- Carpet edges
They may then enter suitcases, bags or clothing and travel home with you.
After travelling, inspect your luggage before storing it. You should also wash suitable clothing before putting it back into wardrobes or drawers.
Can Second-Hand Furniture Cause Bed Bugs?
Yes.
Second-hand beds, mattresses, sofas and upholstered furniture can sometimes carry bed bugs or eggs.
Furniture may look clean from the outside while insects remain hidden inside:
- Seams
- Joints
- Cracks
- Screw holes
- Upholstery
- Wooden frames
For this reason, inspect used furniture carefully before bringing it into your property.
Taking discarded mattresses, beds or sofas from the street carries an especially high risk.
Where Do Bed Bugs Hide After Entering a Property?
Bed bugs prefer dark, narrow and protected spaces.
Common hiding places include:
- Mattress seams and piping
- Bed frames
- Headboards
- Divan bases
- Storage beds
- Bedside furniture
- Sofas
- Upholstered chairs
- Skirting boards
- Carpet edges
- Cracks in furniture
- Behind loose wallpaper
- Around electrical fittings
- Luggage and storage boxes
They can squeeze into very small spaces. This is one reason infestations can be difficult to locate without a detailed inspection.
Why Do Bed Bug Infestations Spread So Quickly?
A small problem can become harder to control if it is left untreated.
Bed bugs can remain hidden for long periods. During that time, they may continue reproducing without being noticed.
The infestation may spread more quickly when:
- Infested furniture is moved between rooms
- Clothing is moved without being treated
- Suitcases remain near sleeping areas
- Only the mattress is treated
- Adjoining rooms are not checked
- DIY sprays are repeatedly used without a full treatment plan
- Treatment is stopped when activity temporarily decreases
For this reason, it is important to identify the full extent of an infestation before treatment begins.
Does Poor Hygiene Cause Bed Bugs?
No.
Bed bugs are attracted to a human host, not dirt.
They can be found in:
- Clean homes
- Luxury hotels
- Rental properties
- Student accommodation
- Hostels
- Offices
- Public buildings
- Shared housing
However, heavy clutter can make treatment more difficult because it creates more hiding places.
Reducing clutter can help with inspection and treatment. However, cleaning alone will not usually eliminate an established infestation.
How Can You Prevent Bed Bugs From Spreading?
If you suspect bed bugs, avoid moving belongings unnecessarily between rooms.
Useful precautions include:
- Keep affected belongings in the same room until advised otherwise
- Wash suitable clothing and bedding at a high temperature
- Tumble-dry suitable fabrics using a hot cycle
- Store cleaned items in sealed bags
- Inspect luggage after travelling
- Avoid bringing discarded furniture indoors
- Check second-hand furniture carefully
- Reduce clutter around sleeping areas
- Inspect mattress seams regularly
- Report suspected activity quickly in shared accommodation
Early action can help prevent a small infestation from spreading into additional rooms.
What Should You Do If You Find Bed Bugs?
If you find a live bed bug or other evidence of an infestation, avoid moving mattresses, bedding or furniture around the property.
Moving infested items can carry insects into areas that were previously unaffected.
A professional inspection can help determine:
- Which rooms are affected
- Where bed bugs may be hiding
- Whether adjoining areas need inspection
- What preparation is required
- Which treatment method may be suitable
For established infestations, our professional bed bug treatment in East London service is available for homes, flats, hotels and commercial premises.
Why DIY Treatment May Make the Problem Harder to Control
Shop-bought products may kill some exposed bed bugs. However, they may not reach insects hiding inside furniture or structural gaps.
DIY treatment can fail when:
- Only visible insects are sprayed
- The mattress is treated but the bed frame is ignored
- Eggs remain hidden
- Incorrect products are used
- Too much insecticide is applied
- Infested belongings are moved into other rooms
- Follow-up treatment is not completed
Do not mix different pesticides or repeatedly apply products to the same area without following the instructions.
Incorrect treatment can make the infestation harder to manage.
When Is Professional Bed Bug Treatment Needed?
Professional treatment may be appropriate when:
- Live bed bugs have been found
- Activity is present in more than one room
- DIY treatment has not worked
- The infestation keeps returning
- A rental property is affected
- A hotel or serviced accommodation property is affected
- Neighboring rooms may also be involved
A technician can inspect likely hiding places and assess how far the infestation has spread.

How to Reduce the Risk of Bed Bugs Returning
No property can be completely protected from bed bugs. However, a few precautions may reduce the risk.
- Inspect luggage after travelling
- Avoid placing suitcases directly on hotel beds
- Wash suitable travel clothing before storing it
- Check second-hand furniture carefully
- Keep stored textiles in sealed containers
- Inspect beds and mattresses regularly
- Reduce unnecessary clutter
- Seal obvious gaps around floors and walls
- Report suspected activity early
- Avoid moving untreated furniture between rooms
The earlier bed bugs are detected, the easier it is usually to prevent them from spreading.
