What is the preferred host of the common bedbug?

The preferred host of the common bedbug is humans. Bedbugs are parasitic insects that feed primarily on human blood, which provides the necessary nutrients for their development and reproduction. They have evolved to thrive in environments where humans reside, such as homes, hotels, and other accommodations. This strong association with humans makes them adept at locating and feeding on their hosts, usually during the night when people are asleep.

While bedbugs can technically feed on other warm-blooded animals, including dogs, rodents, and birds, these are not their primary or preferred sources of sustenance. The chemical signals and body heat produced by humans attract bedbugs, making them especially effective at finding and feeding on human hosts.
