Scabies Vs Bed Bugs: What’s the Difference?

Scabies and bed bugs are both irritating pests that cause itchy bites. Since these bites appear the same and cause itching and irritation, they are often mistaken for each other. Sometimes, these bites also look like mosquito bites, increasing the confusion even more. 

It is when having detailed insight between the two and comparing scabies vs. bedbugs under different aspects helps. 

In this article, you will learn how these two parasitic insects differ from each other. By the end of the article, you will also learn how to treat their bites effectively. 

Difference Between Scabies and Bed Bugs 

What Is Bedbugs?

Bed Bugs are small parasitic insects with flat and oval bodies (1). They do not have wings but six legs through which they crawl and reach the human body to feed on their blood. Besides humans, bed bugs also feed on the blood of other mammals like cats and dogs. 

These tiny insects stay hidden between the seams of your mattresses and upholstery where the place is dark and dry. If you see any of the below, it could indicate bedbug infestation-

• When bed bugs get crushed, they leave reddish marks on the bedding 
• Bedbug excreta may leave dark brown spots 
• Small eggs or eggshells 

They make their way to the human body by traveling on used clothes, furniture, luggage, etc. Luckily, other than causing itchy skin, these bed bugs do not cause any other disease. 

What Is Scabies?

An infestation of scabies mites is called scabies (2). 

Scabies mites are very tiny (microscopic) mites that are not visible to the naked eye. They are often termed ticks and have a round sac-like body. They are also wingless like bedbugs but have eight legs. Also, scabies do not have eyes. 

An impregnated scabies lays 2 to 3 eggs daily in a burrow that it creates on the upper skin surface. Once hatched, these larvae travel to the skin, where they grow and spread to other body parts. Scabies mites can spread from skin-to-skin contact or by using clothes or bedding for people with scabies mite infestation.

Symptoms of Scabies Vs Bed Bugs

When the bedbug bites, the skin develops itchy and red welts in a cluster that usually appear in a zigzag row. You can see 3 to 5 clusters of bites in the body part. Sometimes, these bites look like mosquito bites or hives. They also overlap the symptoms of eczema. 

Some people develop allergic reactions to bedbug bites, leading to pain and swelling in the bitten areas (3). 

On the other hand, the bites of scabies mites will cause severe itching that will get worse over time. You will see tiny bumps and patchy rashes on the skin surface. These bumps appear in irregular skin-colored rows that are the tunnels where mites lay eggs.  

Scabies mites form tunnels in the skin folds (4), such as-

• between fingers
• inner wrists
• inner elbows
• nipples
• armpits
• shoulder blades
• waist
• knees
• buttocks

The symptoms of bedbugs can be managed by using antihistamines and over-the-counter creams to reduce swelling and itching. If the discomfort and swelling is severe, you can visit a doctor to get prescription medicines.

There are no home remedies or over-the-counter medications for scabies. Therefore, visit a doctor to get prescription medicines. 

How Do You Remove Scabies or Bed Bugs?

Removing infestation is the first step to prevent bites. 

For bedbugs, you need to manage your home and bedding. For instance, washing clothes, upholstery, and bedding in warm water is essential, as these are the places where bedbugs hide. 

Vacuum your furniture and seal their cracks. You may also need to check the cracks in walls and floors and seal them. In case of severe infestation, call a professional pest removal service. 

For scabies, wash your clothes, bedding, towels, and other fabrics in warm water. Dry them under the sun or on high heat. 

When scabies do not get human skin to live and feed, they die within 2 to 3 days. So, try to avoid physical contact with the things that you believe are infested with scabies mites.
