Sometimes scratching may cause blisters. Bed bug bites appear in clusters or in a linear pattern. That’s because bed bugs crawl on your skin, making several bites before moving to another location.

Flea Bites – Flea bites often appear to be small bumps with red patches around them. Just like bed bug bites, flea bites are itchy and may break when scratched excessively. However, since fleas can jump, their bites tend to be scattered all over your skin.

Skin Reaction to the Bites 

Bed Bug Bites – Different people will have varied reactions to bed bug bites depending on the sensitivity of their skin.

Do The Bites Cause Infection?

Flea Bites – Flea bites can take between one day and two weeks to heal depending on the sensitivity of your skin. Most people will not experience any serious reactions to flea bites. In fact the symptoms might go away within one or two days.
