10 Fascinating Facts About Bed Bugs (And What They Mean for Your Home or Business)

Bed Bugs Facts

Bed bugs are one of the UK’s most persistent and misunderstood pests. Small, resilient and notoriously difficult to eliminate, they can quickly turn a minor issue into a major infestation.

Whether you’re facing a current issue, have experienced bed bugs in the past, or want to stay informed, here are 10 fascinating facts about bed bugs, and why they matter.

1) Bed bugs aren’t a sign of poor hygiene.

One of the biggest myths? That bed bugs only infest dirty environments.

The reality: Bed bugs are attracted to people, not cleanliness. They can infest homes, hotels, public transport and workplaces, regardless of how clean or well maintained they are.

Why it matters: Anyone can be affected, so early detection is key.

2) They’re expert hitchhikers.

Bed bugs don’t just appear – they travel.

They can hitchhike on luggage, clothing, second-hand furniture, and public transport, spreading easily between locations. This is why activity typically increases during the summer months, when people travel more frequently.

Why it matters: Infestations often begin after travel or when second-hand items are brought into a property.

3) Bed bugs are generally most active at night.

These pests are most active while you sleep. They are attracted to body heat and carbon dioxide in your breathe, before returning to their hiding spots.

Why it matters: You may not see them – but that doesn’t mean they aren’t there

4) You probably won’t feel their bite.

Bed bug bites are often painless at the time.

They release an anaesthetic and anticoagulant as they feed, which prevents you from feeling the bite and allows them to feed undisturbed.

Why it matters: Small red bite marks can appear hours or days later, making infestations harder to identify early.

5) They can live for months without feeding.

Bed bugs are incredibly resilient. In favourable conditions, they can survive for several months and in some cases up to a year without feeding on blood.

Why it matters: Simply leaving a room or property vacant won’t eliminate bed bugs, they can remain dormant and re-emerge when the next guest arrives. Specialist bed bug heat treatments provide a fast, effective way to eradicate an infestation.

6) A single female can start an infestation.

Bed bugs reproduce quickly.

A single female can produce hundreds of eggs over her lifetime, often concealing them within cracks and crevices.

Why it matters: Small infestations can escalate rapidly without professional intervention.

7) They don’t just live in beds.

Despite the name, bed bugs hide in far more than mattresses.

Common hiding places include:

  • Furniture and sofas
  • Skirting boards
  • Electrical sockets
  • Luggage and personal belongings

Why it matters: Treating only the bed won’t eliminate the infestation.

8) Bed bugs are visible – but easy to miss.

Adult bed bugs are visible to the naked eye and are approximately the size of an apple seed (4–7mm). However, they can hide in very small spaces due to their flat bodies.

Why it matters: Regular inspections are essential, especially in high-risk environments.

9)  They don’t spread disease – but still cause serious issues.

The good news: bed bugs are not known to transmit diseases to humans.

The bad news: they can cause:

  • Itching and skin irritation
  • Sleep disruption
  • Anxiety and stress

Why it matters: The impact is often psychological and operational – particularly for businesses a bed bug infestation can be costly and cause reputational damage.

10) Bed bugs are becoming more common in the UK.

Bed bug activity has increased in recent years.

This is largely due to:

  • Increased international travel
  • Urban living and higher density
  • Resistance to some insecticides

Why it matters: Bed bugs are no longer rare – they’re a growing, ongoing challenge however there are various treatments that can mitigate, detection and control bed bug infestations. Click here to find out more about Vergo’s Bed Bug Control Services.
