How Do Bed Bugs Spread from House to House

First: Bed Bugs Don't Fly or Jump

Bed bugs are crawling insects.

Unlike fleas, they cannot jump. Unlike mosquitoes, they cannot fly.

They also don't normally live permanently on a person's body or in their hair like lice.

Instead, they spend much of their time concealed in harbourages and emerge when seeking a blood meal.

That makes passive transport particularly important.

1. Travel and Luggage

Travel is one well-known way bed bugs can be transported between locations.

A bug may hide in:

• suitcase seams;
• zip areas;
• folded clothing;
• bags;
• fabric cases; or
• other belongings left close to an infested sleeping or resting area.

The person then carries the item home, giving the insect an opportunity to leave the luggage and establish a new harbourage.

2. Second-Hand Furniture

Used furniture is another important potential transport route.

Bed bugs aren't restricted to mattresses.

They can hide in:

If you're buying used furniture, inspect it carefully before bringing it into a bedroom or living area.

We've covered this in more detail in: Signs of Bed Bugs After Buying Second-Hand Furniture .

Should You Throw Away Second-Hand Furniture?

Not automatically.

The important issue is whether the item is actually infested and whether it can be inspected and treated effectively.

If you find evidence of bed bugs, don't simply carry the item through the house or put it outside where somebody else may take it.

Movement itself can spread the problem.

3. Bags, Coats and Personal Belongings

Bed bugs don't normally ride around on people in the way that lice live on a host.

But belongings can occasionally provide temporary hiding places.

Potential examples include:

• rucksacks;
• handbags;
• laptop bags;
• overnight bags;
• coats;
• blankets; and
• other belongings placed close to an active infestation.

This is why bed bug spread is better thought of as movement with belongings rather than people themselves being infested.

Can Visitors Bring Bed Bugs Into Your House?

It is possible, but don't panic every time somebody visits.

The risk arises if a bed bug happens to be concealed in something the visitor brings with them.

Simply being near a person who has bed bugs at home doesn't mean a bed bug will automatically transfer to you.

Bed bugs aren't spread from person to person like an infectious illness.

4. Moving House

Moving belongings from an infested property can transfer the infestation to the new address.

Potential transport items include:

• beds;
• mattresses;
• sofas;
• boxes;
• bags;
• clothing;
• bedding; and
• other furniture.

If bed bugs are known to be present, dealing with the infestation before or as part of the move is far preferable to transporting untreated belongings and hoping the insects don't come too.

5. Storage and Transport

Items can also be moved through:

• storage facilities;
• removal vehicles;
• temporary accommodation;
• student accommodation;
• shared housing; and
• other environments where possessions from different locations are moved or stored.

This doesn't mean that using a removal company or storage unit is inherently high risk.

It simply illustrates why bed bug spread is closely connected with movement of belongings.

6. Can Bed Bugs Spread Through Laundry?

Bed bugs can potentially be transported with laundry, laundry bags and baskets if those items come from an infested area.

The washing machine itself isn't necessarily the main risk.

The important part is how potentially infested material is:

• collected;
• bagged;
• carried;
• washed or dried; and
• stored afterwards.

Suitable heat during laundering or tumble-drying can kill bed bugs when the required thermal exposure reaches them, but always follow the care instructions for the fabric.

7. Can Bed Bugs Spread Between Flats?

Yes, movement between adjoining units is possible.

This is particularly relevant in flats, HMOs and other multi-unit buildings.

Bed bugs can crawl and may use existing gaps or service routes within a building.

Potential routes can include:

• gaps around pipes;
• service penetrations;
• cracks;
• cable routes;
• gaps around fittings; and
• other structural connections.

However, finding bed bugs in two neighbouring flats doesn't automatically prove exactly which route they used or which property was affected first.

Can Bed Bugs Spread Through Walls?

Bed bugs don't chew their way through solid walls.

But they can crawl through existing openings and connected spaces where suitable routes are available.

That distinction matters.

A wall isn't automatically a bed bug motorway, but gaps around pipes, cables and building features can potentially connect areas.

For more information, see: Are Bed Bugs in My Walls? .

Can Bed Bugs Spread From Room to Room?

Yes.

They can spread actively by crawling, but people can also spread them accidentally by moving infested belongings.

Common mistakes include:

• moving bedding to another bedroom;
• sleeping permanently in another room;
• moving an untreated mattress;
• carrying furniture around the property;
• moving piles of clothing; and
• placing infested possessions in an unaffected room.

How Quickly Can Bed Bugs Spread?

There isn't one fixed timetable.

How quickly an introduction develops into a larger infestation depends on factors including:

• how many bugs were introduced;
• their life stages;
• whether suitable hosts are available;
• temperature;
• available harbourages;
• whether the infestation is detected early; and
• whether effective treatment is carried out.

A small introduction can remain unnoticed for some time because bed bugs are excellent at hiding and not everybody develops an obvious reaction to bites.

Can Bed Bugs Spread on Pets?

Bed bugs can feed on animals, but they don't normally live permanently in an animal's coat like fleas.

Pet bedding, furniture and nearby cracks may still be worth inspecting in an infested property.

The greater concern is the environment where the pet and people rest, rather than treating the animal as though it were carrying a flea infestation.

Can You Pick Up Bed Bugs on Public Transport?

It is possible for bed bugs to be transported through many environments where people and belongings move.

But it is difficult to assign a meaningful risk to an individual bus, train or seat without evidence of an infestation.

Hotels, homes, accommodation and other places containing established harbourages provide more obvious opportunities for prolonged exposure.

The useful prevention message is therefore awareness without panic.

Bed Bug Spread Myth: Dirty Houses Cause Bed Bugs

They don't.

A clean property can acquire bed bugs just as an untidy property can.

Clutter can make inspection and treatment more difficult because it provides additional hiding places, but dirt itself doesn't explain how an infestation arrived.

Bed Bug Spread Myth: If You Can't See Them, You Don't Have Them

Early infestations can be difficult to find.

Bed bugs commonly conceal themselves in narrow cracks and joints around sleeping and resting areas.

Physical inspection is therefore much more useful than simply looking across the room for a bug.

See our guide to where bed bugs hide during the day .

Bed Bug Spread Myth: One Spray or Fogger Will Solve It

Bed bug control depends on reaching the infestation effectively.

Aerosols, sprays or fogging products should never be assumed to provide complete control simply because they kill exposed insects.

Hidden harbourages, product choice, resistance, application, treatment coverage and follow-up can all influence the result.

Appropriately selected insecticides can form part of bed bug control, but they need to be used correctly and according to the product label.

How to Stop Bed Bugs Spreading Around Your Own Home

How to Avoid Taking Bed Bugs to Someone Else's House

If you know or strongly suspect you have an infestation, sensible precautions include:

• avoiding taking unnecessary bags or soft items to another property;
• keeping potentially exposed belongings contained;
• treating laundry appropriately;
• not giving away furniture;
• avoiding transferring bedding or pillows; and
• dealing with the infestation promptly.

You don't need to treat yourself as contagious. The goal is simply to reduce the chance of transporting a hidden insect in your belongings.

Can Heat Treatment Help Stop an Infestation Spreading?

Professional heat treatment is one option for established bed bug infestations.

When sufficient thermal exposure reaches the insects, heat can kill eggs, nymphs and adults.

Unlike a treatment that depends entirely on an insect crossing a treated surface, heat can affect bugs while they remain concealed — provided the required temperature and exposure reach the harbourage.

This is why professional treatment requires airflow management and temperature monitoring rather than simply making a room feel hot.

What to Do If You've Just Found a Bed Bug

Don't start moving everything out of the room.

Instead:

• keep the specimen if possible for identification;
• inspect the mattress and bed frame;
• check the headboard and nearby furniture;
• look for faecal spotting, cast skins and eggs;
• avoid moving potentially infested belongings; and
• decide on a treatment strategy based on the evidence.

If treatment is being arranged, see our Bed Bug Heat Treatment Preparation Checklist .

The Bottom Line

Bed bugs are successful travellers because they don't need wings or jumping ability.

They use us and the things we move.

Luggage, furniture, bags, bedding and other belongings can transport a hidden bug from one location to another, while adjoining properties can sometimes provide additional crawling routes.

The best defence is therefore not panic or avoiding other people.

It is:

• early identification;
• careful inspection;
• avoiding unnecessary movement of potentially infested belongings;
• containing exposed items appropriately;
• checking adjoining areas where necessary; and
• using an effective treatment strategy when an infestation is confirmed.
