Introduction

Finding unexplained bites on your skin can be alarming, especially if you’ve heard about Lyme disease and other insect-borne illnesses. One common question people ask is: Can you get Lyme disease from a bed bug bite?

Based on current scientific evidence, there is no confirmed evidence that bed bugs transmit Lyme disease to humans. Lyme disease is a tick-borne illness caused primarily by the bacterium Borrelia burgdorferi, and it is most commonly spread through the bite of infected blacklegged ticks (also known as deer ticks).

Although bed bugs and ticks are both small blood-feeding insects or arthropods that can bite humans, they differ significantly in their biology, behavior, and ability to transmit diseases. Understanding these differences can help reduce unnecessary worry and ensure you seek appropriate medical care if you experience symptoms after a suspected tick bite.

At Holistic Therapy Tribe, we aim to provide balanced, evidence-based information to help patients, caregivers, wellness practitioners, and healthcare professionals better understand Lyme disease and related health concerns.

What Is Lyme Disease?

Lyme disease is an infectious disease caused primarily by the bacterium Borrelia burgdorferi in North America. It is transmitted through the bite of infected blacklegged ticks (Ixodes scapularis and Ixodes pacificus).

According to the CDC Lyme disease overview, infected ticks generally need to remain attached for a significant period before transmission becomes more likely.

Common Lyme disease symptoms may include:

• Erythema migrans (bull’s-eye) rash
• Fatigue
• Fever
• Chills
• Headache
• Muscle aches
• Joint pain
• Neck stiffness
• Neurological symptoms in some cases

Without timely diagnosis and appropriate treatment, Lyme disease may affect multiple body systems.

What Are Bed Bugs?

Bed bugs (Cimex lectularius) are small, reddish-brown insects that feed on human blood, usually during the night.

Unlike ticks, bed bugs:

• Live in mattresses, furniture, and cracks
• Do not remain attached for long periods
• Feed quickly before hiding
• Cannot fly or jump
• Primarily cause itchy skin reactions

While bed bugs are considered nuisance pests, they are not recognized as vectors for Lyme disease.

Can You Get Lyme Disease from a Bed Bug Bite?

Current Scientific Evidence

The short answer is no.

Although researchers have studied whether bed bugs can carry bacteria and viruses under laboratory conditions, there is currently no evidence that bed bugs transmit Lyme disease to people in real-world settings.

Lyme disease transmission requires specific biological interactions between Borrelia burgdorferi and blacklegged ticks that have not been demonstrated in bed bugs.

According to the Mayo Clinic Lyme disease guide, Lyme disease is spread through infected ticks—not bed bugs.

Why Don’t Bed Bugs Spread Lyme Disease?

Scientists believe several biological differences explain why bed bugs are not known to spread Lyme disease.

Different Feeding Behavior

Ticks often remain attached for many hours or even days while feeding.

Bed bugs feed for only a few minutes before leaving.

This short feeding period appears unsuitable for transmitting Borrelia burgdorferi.

Different Digestive Biology

Ticks provide an environment that allows Lyme bacteria to survive, multiply, and migrate into the tick’s salivary glands before transmission.

Researchers have not demonstrated that bed bugs support this same process.

No Confirmed Human Transmission

Despite decades of research, scientists have not documented confirmed cases of Lyme disease being transmitted by bed bugs.

According to PubMed Lyme disease research, available evidence continues to support ticks as the primary vector.

Bed Bug Bite vs. Tick Bite

Understanding the differences may help reduce confusion.

Bed Bug Bites

Often appear as:

• Small red bumps
• Clusters or straight lines
• Very itchy skin
• Bites noticed after sleeping
• Multiple bites on exposed skin

Tick Bites

May include:

• A visible attached tick
• Single bite location
• Minimal itching initially
• Erythema migrans rash in some cases
• Flu-like symptoms days or weeks later

Not every tick carries Lyme disease, and not every tick bite results in infection.

Can Bed Bugs Carry Other Diseases?

Researchers have investigated whether bed bugs might carry various microorganisms.

Although bed bugs can sometimes harbor pathogens in laboratory studies, health authorities have not confirmed them as significant transmitters of infectious diseases to humans.

Their greatest impact is usually related to:

• Skin irritation
• Allergic reactions
• Sleep disruption
• Anxiety
• Secondary skin infections caused by scratching

What Should You Do After a Bed Bug Bite?

Most bed bug bites improve without serious complications.

General recommendations include:

• Avoid scratching
• Keep the affected area clean
• Monitor for signs of infection
• Consult a healthcare professional if symptoms worsen

If you believe you were bitten by a tick rather than a bed bug—or if you develop fever, fatigue, joint pain, or an expanding rash after outdoor exposure—seek prompt medical evaluation.

Preventing Tick Bites and Lyme Disease

Because ticks—not bed bugs—are responsible for transmitting Lyme disease, prevention should focus on reducing tick exposure.

Helpful prevention strategies include:

Wear Protective Clothing

Long sleeves and long pants reduce exposed skin.

Use EPA-Registered Tick Repellents

Follow label directions carefully.

Perform Tick Checks

Inspect your body, clothing, children, and pets after spending time outdoors.

Remove Attached Ticks Promptly

Prompt removal may reduce the likelihood of disease transmission.

The CDC guide to tick removal explains the proper technique.
