Experiencing itching, rashes, or bites can be unsettling, and determining whether the cause is bed bugs or scabies is crucial for proper treatment. While both conditions lead to skin irritation, they stem from entirely different sources and require distinct approaches to eradication.
In this article, we’ll break down the key differences between
bedbugs and scabies, from their symptoms and causes to how you can treat and prevent them.
What Are Bed Bugs?
Bed bugs, small and parasitic insects that feed on human blood, are primarily active at night. These pests hide in mattresses, furniture, and wall crevices during the day and emerge in the dark to feed.
Characteristics of Bed Bugs
-
Size:
About 4-5 mm long (similar to an apple seed).
-
Color:
Reddish-brown, darkening after feeding.
-
Shape:
Flat and oval with short antennae.
-
Movement:
Crawls quickly but does not jump or fly.
Symptoms of Bed Bug Bites
Bed bug bites are often not spotted at first, but they can cause increasing discomfort over time. The following signs may indicate bed bug activity:
- Red, swollen welts that usually appear in clusters or a straight line.
- Commonly found on exposed skin like the arms, neck, and face.
- Mild to severe itching, depending on sensitivity.
- Delayed reaction, where symptoms appear hours or even days later.
What Is Scabies?
Scabies are a skin infection, and microscopic mites that burrow into the skin are responsible for it. These pests lay eggs under the skin and generally result in an intense allergic reaction.
Physical Characteristics of Scabies
-
Size:
Extremely small (about 0.2 mm), invisible to the naked eye.
-
Shape:
Round, oval bodies, difficult to spot without a microscope.
-
Behavior:
Burrow into the skin, causing intense itching and rashes as they lay eggs.
Symptoms of Scabies
-
Rash:
Red, bumpy patches that may blister.
-
Common Locations:
Found in skin folds, including the armpits, groin, fingers, and elbows.
-
Intense Itching:
Especially severe at night, when mites are most active.
-
Burrow Tracks:
Thin, wavy lines where mites have tunneled beneath the skin.
Key Differences Between Bed Bugs and Scabies
Despite their similar effects on the skin, bed bugs and scabies differ significantly in their cause, spread, and treatment.
| Feature |
Bed Bugs |
Scabies |
| Cause |
Insects that feed on blood |
Mites that burrow under the skin |
| Transmission |
Spread via furniture, bedding, and travel |
Spread through direct skin contact or shared fabrics |
| Symptoms |
Red welts in clusters or rows |
Rash with blisters, sores, and burrow marks |
| Itching |
May take time to develop |
Immediate and severe, especially at night |
| Location |
Found in mattresses, furniture, and cracks |
Infestation occurs within the skin, often in folds |
How to Identify Bed Bugs vs Scabies
Determining whether you have bed bugs or scabies requires careful observation of symptoms and surroundings. Here’s how to tell the difference:
Check for Physical Signs
-
Bed Bugs:
Look for live insects, dark faecal spots, shed skins, or blood stains in bedding and furniture.
-
Scabies:
Since mites are too small to see, check for a persistent rash, intense nighttime itching, and burrow tracks.
Analyze the Bite Pattern
-
Bed Bug Bites:
Occur in rows or clusters, typically on exposed skin like arms, face, and neck.
-
Scabies Rash:
Found in skin folds, accompanied by burrow tracks where mites have tunnelled under the skin.
Treatment for Bed Bugs vs Scabies
Since bed bugs and scabies are entirely different infestations, treating them requires different approaches.
How to Get Rid of Bed Bugs?
Bed bug infestations can be hard to eliminate and often require professional intervention. You can follow the below steps to ease the process:
- Take help from a pest control professional if the infestation is severe.
- Wash all bedding, clothing, and linens in warm water and drying on high heat.
- Using protective mattress covers to trap any remaining bed bugs.
- Applying over-the-counter anti-itch creams (e.g., hydrocortisone) for symptom relief.
How to Treat Scabies?
Because scabies and mites live inside the skin, treatment must eliminate them completely. The most effective methods include:
- Prescription medications such as permethrin cream or oral ivermectin to kill mites.
- Wash all clothing, bedding, and towels in warm water to prevent re-infestation.
- Avoid scratching to prevent secondary skin infections.
- Treating all household members who have had prolonged contact with an infected person, even if they have no symptoms.
Prevention Tips for Bed Bugs and Scabies
Avoiding an infestation is always easier than treating one. These measures can help keep both pests at bay.
How to Prevent Bed Bugs?
-
Inspect hotel rooms and luggage after traveling.
-
Block cracks and crevices where bed bugs might hide.
-
Use bed bug-proof mattress covers to protect against infestations.
How to Prevent Scabies?
-
Avoid prolonged skin contact with infected individuals.
-
Wash and disinfect bedding, towels, and clothing regularly.
-
Seek early treatment to prevent spreading scabies to others.

Fact |
| Bed bugs transmit diseases. |
Bed bugs do not cause diseases, though their bites can cause allergic reactions. |
| Scabies are caused by poor hygiene. |
Scabies can affect anyone, regardless of hygiene, as they spread through close contact. |
| You can see scabies mites with the naked eye. |
Scabies mites are microscopic and cannot be seen without a microscope. |
| Bed bugs only infest dirty homes. |
Bed bugs can invade any home, clean or dirty, as they are attracted to warmth and carbon dioxide. |
| Scabies can be treated with over-the-counter creams. |
Effective treatment for scabies usually requires prescription medications from a healthcare provider. |
