Bed Bugs vs Scabies | How to Identify and Treat them?

Bed bugs and scabies are two distinct parasitic infestations that affect humans, causing discomfort and irritation. It is crucial to differentiate between these infestations for accurate diagnosis, appropriate treatment, and effective prevention strategies. In this comprehensive article, we will delve into the detailed characteristics of bed bugs vs scabies, including their appearance, life cycles, behaviors, signs of infestation, transmission methods, diagnostic approaches, treatment options, and preventive measures.

I.Characteristics of Bed Bugs


Bed bugs are visible to the naked eye, measuring around 4-5 millimetres in length. They have an oval-shaped body with a flattened appearance, allowing them to hide easily in narrow spaces. Adult bed bugs are reddish-brown in colour, while nymphs (young bed bugs) are smaller and lighter in colour.

Life cycle:

Bed bugs undergo a simple metamorphosis, progressing through three main stages: egg, nymph, and adult. Female bed bugs lay hundreds of eggs during their lifetime, which typically hatch within one to two weeks. The nymphs moult several times before reaching adulthood, and the entire life cycle can take several weeks to several months, depending on environmental conditions.

Behaviour and Habits: 

Bed bugs are primarily active at night and are attracted to the warmth and carbon dioxide emitted by their hosts. They feed on the blood of humans or animals by piercing the skin with their elongated mouthparts. After feeding, they retreat to their hiding places, often located near their hosts’ resting areas. Common hiding spots include mattresses, box springs, bed frames, furniture, and cracks in walls or floors.

Signs of Infestation:

 Indicators of a bed bug infestation include:

  • Bites: Bed bug bites typically manifest as red, itchy welts that appear in a linear or clustered pattern on the skin. However, not everyone reacts to bed bug bites, so the absence of visible bites does not rule out an infestation.
  • Blood stains: Bed bugs may leave small blood stains on bedding or nearby furniture when they are crushed or engorged with blood.
  • Fecal matter: Bed bugs excrete dark fecal spots, resembling tiny black dots, on bedding or infested areas.

II. Characteristics of Scabies

Description and Causes: 

Scabies is a highly contagious skin infestation caused by the Sarcoptes scabies mite. These microscopic mites burrow into the upper layer of the skin, causing intense itching and a characteristic rash. Scabies is commonly transmitted through direct skin-to-skin contact and can spread rapidly in crowded living conditions.


Common symptoms of scabies include:

  1. Intense itching: The primary symptom of scabies is severe itching, particularly at night or after a hot shower. The itching is a result of the body’s allergic reaction to the mites and their waste products.
  2. Rashes: Scabies infestation leads to the development of a rash characterized by small red bumps, blisters, or pimple-like lesions. The rash often appears in the webbing between the fingers, wrists, elbows, armpits, waistline, and genital area.
  3. Burrows: Scabies mites create thin, irregular burrows or tracks in the skin, which may appear as tiny raised lines. These burrows are often difficult to see without magnification.


Scabies are primarily transmitted through direct, prolonged skin-to-skin contact with an infected individual. It can also be spread by sharing infested clothing, bedding, or towels. Although less common, indirect transmission from contaminated surfaces is possible as the mites can survive outside the human body for a limited time.

Risk Factors: 

Several factors increase the risk of scabies infestation, including:

  1. Crowded living conditions: Scabies are more prevalent in environments where close contact with others is common, such as nursing homes, dormitories, or prisons.
  2. Close contact with infected individuals: Living or sleeping in close proximity to someone with scabies increases the chances of transmission.
  3. Weakened immune system: Individuals with weakened immune systems, such as those with HIV/AIDS or certain medical conditions, may be more susceptible to scabies infestations.

III. Differences between Bed Bugs vs Scabies

Size and Appearance:

 Bed bugs are visible to the naked eye, measuring around 4-5 millimeters in length. They have a distinct reddish-brown color and an oval-shaped, flattened body. Scabies mites, on the other hand, are microscopic, measuring approximately 0.3-0.4 millimeters in length, and cannot be seen without magnification.

Bites and Rashes:

 Bed bug bites often appear as red, itchy welts on exposed areas of the skin. The bites may be arranged in a linear or clustered pattern. In contrast, scabies cause a characteristic rash consisting of small red bumps, blisters, or pimple-like lesions. The rash typically appears in the webbing between fingers, wrists, elbows, and other warm areas of the body.

Infestation Patterns: 

Bed bug infestations are usually localized to areas where people sleep or spend extended periods, such as beds, sofas, or recliners. While bites may appear on various parts of the body, bed bugs tend to congregate in these specific areas. Scabies infestations, however, can occur all over the body, including the hands, feet, wrists, armpits, waistline, and genital area. The burrows created by scabies mites can be found in different locations on the skin.

Transmission Methods: 

Bed bugs are primarily transmitted through infested items, such as used furniture, clothing, or luggage. They can hitch a ride on these objects and be transported to new locations. Scabies, on the other hand, spreads through direct skin-to-skin contact with an infected person. Sharing personal items, such as clothing or bedding, with an infested individual can also lead to transmission.

Diagnosis and Treatment

Diagnostic Methods for Bed Bugs: 

Diagnosing a bed bug infestation may involve:

  1. Visual inspection: A professional pest control expert or knowledgeable individual may visually inspect the suspected areas for live bed bugs, shed skins, or fecal stains.
  2. Identification of live bugs or signs: Identifying live bed bugs, eggs, or cast skins can confirm an infestation. Bed bug fecal matter, which appears as dark spots or smears, may also be detected.
  3. Monitoring techniques: The use of bed bug traps or monitors can help capture and identify bed bugs in infested areas.

Diagnostic Methods for Scabies: 

Diagnosing scabies typically involves:

  1. Examination of skin scrapings: A healthcare provider will take a small scraping from the affected skin area and examine it under a microscope. The presence of scabies mites, eggs, or fecal matter confirms the diagnosis.

Treatment Options for Bed Bugs:

Treating a bed bug infestation may involve:

  1. Professional extermination: In severe infestations, it is often recommended to hire a professional pest control company to eliminate bed bugs using insecticides, steam treatments, or heat treatments.
  2. Insecticide applications: In less severe cases, insecticides specifically labelled for bed bug control can be used to treat infested areas.
  3. Heat treatments: Raising the temperature of infested items or the entire room to a level that kills bed bugs is another effective treatment option.
  4. Preventive measures: Regular cleaning, reducing clutter, using protective covers on mattresses and pillows, and inspecting secondhand items can help prevent bed bug infestations.

Treatment Options for Scabies: 

Treating scabies may involve:

  1. Prescription medications: Topical creams or lotions containing scabicide medications, such as permethrin or ivermectin, are commonly prescribed to kill scabies mites.
  2. Personal hygiene practices: Maintaining good personal hygiene, such as regular bathing and washing of clothes and bedding in hot water, helps eliminate mites and reduce the risk of transmission.
  3. Treating close contacts: It is important to identify and treat all individuals who have had prolonged skin-to-skin contact with the infested person to prevent re-infestation.

Prevention and Control

A. Preventive measures for bed bugs: 

To prevent bed bug infestations:

  1. Regular cleaning: Regularly vacuuming, sweeping, and washing bedding can help eliminate bed bugs or eggs.
  2. Reducing clutter: Minimizing clutter in living spaces reduces hiding places for bed bugs.
  3. Using protective covers: Encasing mattresses and pillows with bed bug-proof covers can help prevent infestations.
  4. Inspecting secondhand items: Thoroughly inspecting used furniture, clothing, or other items before bringing them into the home can prevent the introduction of bed bugs.

B. Preventive measures for scabies: 

To prevent scabies infestations:

  1. Practicing good hygiene: Regularly washing hands and maintaining overall cleanliness helps reduce the risk of scabies transmission.
  2. Avoiding close contact with infected individuals: Limiting close skin-to-skin contact with individuals known to have scabies reduces the chances of transmission.
  3. Washing clothes and bedding in hot water: Laundering clothes, bedding, and towels in hot water and drying them on high heat helps kill scabies mites.

Public Awareness and Education: 

Raising public awareness about bed bugs and scabies is crucial for prevention and control. Educating the community about the signs, symptoms, transmission methods, and preventive measures can empower individuals to take appropriate actions.

Response to Outbreaks: 

In the event of outbreaks or infestations, implementing appropriate control measures is essential. These measures may include isolating affected individuals, following treatment protocols, conducting thorough environmental sanitation, and providing education on prevention strategies.
