Health Risks of Bed Bugs – Why You Shouldn’t Ignore an Infestation

More Than Just a Bite

Bed bugs (Cimex lectularius) have made a huge comeback across London and Essex in recent years. While they don’t transmit diseases like some other pests, the health risks of bed bugs go far beyond itchy bites. From skin irritation and infections to anxiety and sleepless nights, their impact on your wellbeing can be serious if left untreated. If you’re not sure whether you’re dealing with them or another skin issue, see our guide on Bed Bug Bites vs Shingles.


What Are Bed Bugs & How Do They Spread?

the health risks of bed bugs and prevention tips

Bed bugs are small, flat, reddish-brown insects that feed on blood, usually at night. They hitchhike on luggage, clothing, furniture, and bedding, and can quickly infest even the cleanest homes.

Common entry points include:

  • Bringing home second-hand furniture without inspection
  • Staying in hotels, hostels, or Airbnbs with undetected infestations
  • Using shared laundry facilities
  • Visitors unknowingly bringing them in

Bed bug bites aren’t just irritating — in some cases they can lead to infections, allergic reactions, or even affect your sleep and mental wellbeing. Learn more about how you get bed bugs and see our full guide on the health risks of bed bugs.

If you’ve spotted any signs, our Bed Bug Control service offers the safest way to stop them spreading.


Physical Health Risks of Bed Bugs

According to Rentokil, the dangers of bed bugs include more than itchy bites:

1. Skin Irritation & Allergic Reactions

Bed bug saliva contains proteins and enzymes that can trigger histamine reactions, leading to red, itchy welts. For some people, these bites can swell, blister, or cause intense itching. In rare cases, severe allergic reactions (anaphylaxis) can occur.

2. Secondary Skin Infections

Persistent scratching can break the skin, creating entry points for bacteria. Rentokil highlights that this can lead to:

  • Impetigo – contagious crusty sores
  • Cellulitis – painful swelling and redness
  • Folliculitis – inflamed hair follicles

3. Anaemia

In severe infestations—especially among children, the elderly, or immunocompromised—repeated blood feeding can contribute to mild anaemia over time.

4. Respiratory Allergies

Bed bug shed skins and faecal particles can become airborne, potentially aggravating asthma or other respiratory conditions in sensitive individuals.


Mental Health & Sleep Disruption

Bed bug infestations don’t just affect the skin—they can hit your mental health hard.

Anxiety & Stress

The constant worry of being bitten at night can cause emotional distress, social withdrawal, and even depression.

Insomnia & Sleep Deprivation

Because bed bugs are nocturnal, many people develop sleeping problems, leading to fatigue, irritability, and weakened immunity. Rentokil notes that this ongoing disruption can amplify anxiety and impact day-to-day functioning.

Psychological Distress

Long-term infestations have been linked to delusional parasitosis—a mental health condition where sufferers believe they are still infested even after eradication.


The Hidden Costs of Bed Bug Infestations

Aside from health concerns, bed bugs carry hidden costs:

  • Financial strain – Multiple treatments, furniture replacement, and follow-up visits add up.
  • Disruption to life – Preparation for treatments can be time-consuming and stressful.
  • Public health risk – Infestations spread easily in communal housing, public transport, and hotels.

Prevention & Early Detection

The earlier you act, the easier it is to eliminate bed bugs.

Signs to look for:

  • Rust-coloured spots on bedding (blood or faeces)
  • Shed skins and tiny white eggs near mattress seams
  • Live bugs hiding in cracks and joints
  • Bites in lines or clusters

Prevention tips:

  • Inspect beds when travelling
  • Wash clothes on a hot cycle after trips
  • Avoid bringing second-hand furniture home without inspection
  • Use mattress encasements and bed bug interceptors

Why Professional Treatment Is Essential

DIY methods often fail to kill eggs or reach deep hiding spots. A professional service like Bugwise ensures:

  • Targeted insecticide treatments
  • Comprehensive inspections
  • Follow-up visits to break the breeding cycle
  • Preparation guidance to maximise results
