Examples of such allergies or infections can be, Flea Bites and Bed Bug Bites. These can cause some serious irritation if not treated. And for that treatment, it is important to understand them, which might be a little difficult as they are very similar.

To help with this, the following are some of the important differences that might help understand them.

Flea Bites vs Bed Bug Bites

The difference between flea bites and bed bug bites is in their appearances. In the case of flea bites, they can easily be found on the lower body (for example, legs or thighs) of a person. The spots on the body are relatively smaller and in circles and are mostly separated from each other. They can happen at any time and sometimes won’t get noticed at first. They are bright or blood-red in color. If not treated properly or itched harshly, they can turn into infections. Whereas bed bug bites are most likely to take place on the upper body, especially back on the person, they are comparatively larger in size as the spots might get connected, they are dull-red in appearance, they can turn into blisters.

Flea Bites vs Bed Bug Bites

Flea Bites are small spots or bumps on the body that are red in color. They mostly take place in the leg, foot, or tight of the individual. They might not be very itchy and do not even hurt in some cases.

They are smaller in size that makes them difficult to detect at first. They can happen at any time of the day and in any weather. They can be treated at home as well.

Bed Bug Bites are also bumps the size of apple seeds on the body. They are caused by the bug that lives under the bed and feeds on human blood for survival. Spots might be attached and hence can become large.

They are not bright red but, in fact, have a dull appearance. Bed bugs do not feed every time but only periodically.

What are Flea Bites?

Flea bites are the bites caused by flea on the animals. Fleas are not able to fly but can only jump from one animal to another, and therefore, this is the means of traveling for them. Some of the common symptoms of flea bites are following:

  • Small red spots on the body.
  • Intense and irritable itching on the spots.

Although they are more likely to take place on the lower body, as mentioned above, fleas cannot fly, and hence it is difficult for them to feed on the upper body part, but that does not imply that they won’t happen on the upper body at all.

Precaution that must be taken to avoid any flea bites:

  • Maintaining the basic hygiene of the house, especially the floor and furniture.
  • In the case of carpet, steaming should be done to clean it.
  • In the case of a pet, pest control should be done regularly.
  • Pets should be washed and cleaned regularly.
  • A flea collar should be used for pets.

What are Bed Bug Bites?

Bed bug bites are bites given by the bed bugs that live on human blood as well. They are oval-shaped spots that are either dull-red or brownish-red in color.

They do not come out during the day, and hence mostly they feed during dark in the night on people, most probably when they are sleeping.

They can be found easily on carpets, box springs, mattresses, bed frames, etc. most of them are found in places where many people visit, or heavy crowds take place, but they also can be found in houses or buildings.

They can be found in the following parts of the body:

  • Face
  • Neck
  • Arms
  • Hands

Although they don’t cause any serious harm to the body in some cases, people might be extremely affected by them. They turn up into blisters and can cause serious itching.

They get a cure after 1 or 2 weeks, but in the following cases, a doctor or a professional should be consulted:

  • Bites do not disappear in a maximum of two weeks.
  • Any other infections are developed due to itching.
  • Any allergic reactions happened.
