Bed bugs are becoming an increasingly common problem across London. They are expert hitchhikers, travelling unnoticed on luggage, clothing and soft furnishings rather than living permanently on people. With millions of passengers using the Underground, taxis and social spaces every day, together with the constant movement through hotels, apartments and short-term rentals, there are more opportunities than ever for bed bugs to spread between properties.
Unlike many household pests, bed bugs are not attracted to dirt or poor hygiene. They are simply looking for a meal and somewhere to hide close to people while they sleep. Understanding the most common causes of bed bugs is the first step towards preventing an infestation.
In this post, we’ll look at the most common causes of bed bugs in London, how they spread from place to place, some of their unusual hiding places, and the practical steps you can take to reduce the risk of bringing them into your home.
Bringing Them Back from Holiday
Whether you’re travelling within the UK or abroad, bed bugs are far more commonly picked up while travelling than most people realise.
When staying in hotels or holiday accommodation:
- Place luggage on a luggage rack rather than the bed or floor.
- Check mattress seams and the headboard before unpacking.
- Keep clothing inside your suitcase where practical.
- Wash travel clothing on a hot wash as soon as you return home.
Many infestations begin after holidays, with bed bugs unknowingly travelling back inside suitcases. However, this is just one place among many where you can catch bed bugs from.
When People Stay Over
Guests are one of the most common ways bed bugs are introduced into a property. This does not necessarily mean they have an infestation at home. Bed bugs can be picked up from a range of locations without anyone realising.
Before guests arrive, wash spare bedding at 60°C and vacuum mattresses, bed frames and surrounding areas. Once they leave, washing bedding again and carrying out a quick inspection can provide valuable peace of mind.
Using Public Transport in London
Millions of journeys are made on London’s transport network every day. While bed bugs do not live on the tube or buses, they can occasionally be carried on bags, coats and luggage as people travel and visit public places around the capital.
This is one reason why bed bugs are able to spread so effectively in major cities. They simply move wherever people go. After returning from a day trip that involves travelling on London transport or wider UK rail networks, it’s worth checking your clothes and luggage when you get home.
Although the risk is lower, taxis can occasionally play a part in the spread of bed bugs. If a previous passenger unknowingly carries bed bugs on their clothing or luggage, the insects can transfer to seats or carpets before hitching a ride with the next occupant.
When You’re Having a Get Together
Although bed bugs usually remain close to sleeping areas, they can occasionally be transported on coats and handbags. This can also apply to having children over to your house, as well as your own kids bring bed bugs home, as these insects can travel with their toys and other accoutrement.
If you are entertaining several guests, avoid piling coats and bags together on beds or upholstered furniture. Instead, keep belongings in a designated area away from bedrooms where possible.
This simple precaution reduces the opportunity for bed bugs to transfer from one person’s belongings to another, or into your own sleeping quarters.
Be Careful with Second-Hand Furniture
Buying pre-owned furniture has become increasingly popular across London, but it can also introduce bed bugs into a property if items are not inspected carefully.
Pay particular attention to mattresses, upholstered chairs, sofas and bed frames. Check seams, joints and hidden corners before bringing furniture indoors. If there is any doubt, it is usually safer to avoid the purchase altogether.
Living In Flats and Shared Buildings
Bed bugs are particularly challenging in flats and multiple occupancy buildings because they can move between neighbouring properties through small gaps around pipework, electrical sockets and wall voids.
Treating only one room rarely solves a bed bug problem if activity exists elsewhere in the building. Professional inspection helps identify the full extent of the infestation and ensures the correct treatment plan is carried out.
Professional Bed Bug Treatment
Bed bugs reproduce quickly and spend much of their time hidden inside cracks, bed frames, furniture and skirting boards, as well as all sorts of other household items. By the time bites become noticeable, an infestation is often well established.
Professional treatment targets the entire infestation, including unseen harbourage areas that DIY products frequently miss. At Diamond Pest Control, our experienced technicians provide effective bed bug treatments across London, helping homeowners, landlords and businesses eliminate infestations safely and thoroughly before they spread further.
