What is the preferred host of the common bed bug?

The common bed bug, scientifically known as Cimex lectularius, has a strong preference for feeding on human blood. Humans are considered the primary host for these pests because they are often found in close proximity to us, particularly in sleeping areas such as beds and bedding. This close association allows bed bugs to easily access their preferred food source during the night when people are typically asleep and less likely to notice a bite.

While bed bugs may feed on other animals such as dogs, rats, or birds when humans are not available, their biological adaptations and behavior have evolved to make humans their most suitable host. Bed bugs are attracted to the carbon dioxide we exhale, our body heat, and the presence of our skin, making us the most favored target for their feeding habits. This preference is significant, as it influences pest control strategies and highlights the need for vigilance in human environments, particularly in places where people sleep or spend prolonged periods of time.
