Bed bugs are small, flat, reddish-brown insects that feed on human blood at night. They hide in mattresses, bed frames, sofas and small cracks near sleeping areas. Once inside a property, they can multiply quickly and spread between rooms if not treated early.
They are not linked to poor hygiene — but they are extremely persistent once established.
Key Facts About Bed Bugs
- Scientific name: Cimex lectularius
- Size: 4–7mm (about the size of an apple seed)
- Active: Mainly at night
- Can fly? No
- Can jump? No
- Can survive without feeding? Up to several months
- Eggs hatch in: 6–10 days
- A single female can lay: Up to 500 eggs in her lifetime
What Do Bed Bugs Look Like?
Adult bed bugs are oval, flat, and reddish-brown. After feeding, they appear darker and more swollen.
Young bed bugs (nymphs) are smaller and lighter in colour, often appearing translucent before their first blood meal.
Because of their flat bodies, they can hide in gaps as thin as a credit card.
Where Do Bed Bugs Hide?
Bed bugs prefer to stay close to where people sleep.
Common hiding places include:
- Mattress seams and labels
- Bed frames and headboards
- Sofa joints and armrests
- Skirting boards
- Electrical socket plates
- Behind loose wallpaper
- Inside divan bases
In London flats and shared housing, we often find them spreading through wall voids and pipe runs between properties.
Signs of a Bed Bug Infestation
The most common signs include:
- Itchy red bites, often in lines or clusters
- Small dark spots (faecal marks) on bedding
- Shed skins near mattress edges
- Tiny white eggs in crevices
- A sweet, musty odour in heavier infestations
Bites alone are not proof. We always advise looking for physical evidence before assuming the cause.
Bed Bugs vs Other Biting Pests
Many people confuse bed bugs with fleas or mites. Here’s a quick comparison:
| Feature | Bed Bugs | Fleas | Dust Mites |
|---|---|---|---|
| Bite timing | Night | Any time | Do not bite |
| Jump | No | Yes | No |
| Live on pets | No | Yes | No |
| Visible to eye | Yes | Yes | No |
| Hide in beds | Yes | Rarely | Yes (microscopic) |
This distinction is important because treatment methods differ completely. If you’re unsure which pest is responsible, see our guide on dust mites vs bed bugs vs fleas or read about other biting bugs that aren’t bed bugs to help narrow down the cause before choosing a treatment approach.
Why Bed Bugs Are Increasing in the UK
Across London & Essex, infestations are commonly linked to:
- Travel (hotels, Airbnb, public transport)
- Second-hand furniture
- High-density housing
- Student accommodation
- Rental property turnover
Bed bugs are excellent hitchhikers. They don’t fly or jump — bed bugs travel in luggage, clothing, and furniture.
Health Impact of Bed Bugs
Bed bugs are not known to transmit disease in the UK.
However, they can cause:
- Intense itching
- Secondary skin infections from scratching
- Sleep disturbance
- Anxiety and stress
In larger infestations, the psychological impact is often worse than the bites themselves.
Can You Get Rid of Bed Bugs Yourself?
Light, early-stage infestations may respond to:
- High-heat washing (60°C+)
- Vacuuming seams and crevices
- Mattress encasements
- Decluttering
However, once bed bugs spread beyond one sleeping area, DIY methods rarely eliminate them completely.
They hide deep inside furniture and structural voids where over-the-counter products cannot reach.
Professional Bed Bug Treatment
For established infestations, professional treatment is normally required.
Effective methods include:
- Targeted residual insecticide application
- Steam treatment to kill eggs
- Follow-up inspections
- Treatment of adjacent rooms
In multi-occupancy buildings, treating one room alone is often not enough.
Early intervention prevents larger structural spread and repeat infestations.
When to Call a Professional
You should consider professional bed bug treatment if:
- Bites are increasing over several days
- You’ve found live insects
- The infestation has spread beyond one room
- DIY sprays haven’t worked
- You live in a flat or shared property
The longer bed bugs are left, the harder they are to eliminate.
Frequently Asked Bed Bug Questions
No. Bed bugs are attracted to people, not dirt. They are just as common in clean homes as they are in cluttered environments. They typically enter properties through luggage, clothing, or second-hand furniture.
Yes. Bed bugs can hide along carpet edges and underneath beds, although they prefer to stay close to sleeping areas such as mattresses and bed frames.
Bed bugs reproduce rapidly. A small infestation can become severe within a few weeks, as a single female can lay hundreds of eggs during her lifetime.
Yes. Bed bugs survive indoors year-round and are unaffected by typical UK winter temperatures inside heated properties.
You may see them during the day if the infestation is heavy, but they usually remain hidden in cracks and crevices and emerge at night to feed.
