Bed bugs and fleas are two of the most common blood-feeding pests that cause discomfort in homes. While both can infest living spaces and bite humans, they have distinct differences in their appearance, behavior, and impact on health. Understanding these differences is crucial for effective pest control. This guide will help you distinguish between bed bugs and fleas, covering their physical traits, behavior, health risks, and prevention methods.
