Bed Bug Vs. Flea Bites

Fleas prefer living on furry animals such as cats and dogs, typically around their neck and belly areas. However, they may bite people incidentally, after jumping off a host. In humans, flea bites generally appear on the legs and ankles.

Bed bugs prefer to eat the blood of humans. They typically will live in beds and other places that give them easy access to human blood. They cannot jump or fly.

The table below shows some key differences between flea bites and bed bug bites:
