Why Do Bed Bugs Need Blood?
Bed bugs need blood to live and grow. Blood gives them the energy to move and reproduce. Without blood, bed bugs cannot survive for long.
After hatching from eggs, bed bugs must feed on blood to grow. They go through several stages before becoming adults. Each stage needs at least one blood meal.

Young bed bugs need blood more often. They can only survive a few weeks without a meal. Adult bed bugs can live longer without blood. Some adults can live up to a year or more without eating.
