Bed bugs are extremely common pests that, literally, suck your blood. Or in other words, a human parasite. They don’t feed on animals unlike fleas, they feed on human blood. Bed bugs are constantly multiplying. They can lay up to 500 eggs in just one lifetime. Imagine 1 bed bug laying 500 eggs – now, imagine 500 bed bugs laying 500 eggs each! This doesn’t seem like the kind of thing you’d want multiplying, does it?
