The three kinds of bed bugs that feed on people are C. lectularius, C. hemipterus, and L. boueti.
C. lectularius and C. hemipterus are the ones you have to worry about if you live in Europe or the U.S. They feed on humans and like to nest in household items like mattresses, sofas, carpets, and even behind wallpaper.
L. boueti is only found in West Africa and South America, as it prefers tropical climates. Unless you live in those regions or have recently traveled there, this type of bug is unlikely to have taken up residence in your home.
Though the first two types of bed bugs will choose to feed on people if possible, L. boueti are mostly interested in bats. They won’t pass up a human blood meal if it’s convenient, but you’re unlikely to encounter this species unless you live in an area with a large bat population.
Common signs of bed bugs in the home are small red bites that often appear in a line or zigzag pattern, as well as dark spotting on carpets, mattresses, and cloth furniture from fecal droppings.
