Bed Bugs (Cimex Lectularius), over time, acquired a resistance to pesticides, and international travel made it possible for bed bugs to hitchhike from parts of the world where they had not been eradicated to here in America.
Bed Bugs are excellent hitchhikers, too. Not only can they travel around the world, but they’re very good at moving from pace to place – from a hotel room to your bedroom, or from that furniture you picked up at a garage sale to the rest of your house.
Once bed bugs get inside your home, they begin multiplying; one female bed bug will lay one to five eggs a day, or an average of 120 eggs in its life. Upon hatching, those juvenile bugs will reach adulthood in three weeks, seeking out blood meals – from you and your family. While you’re sleeping, by zeroing in on the carbon dioxide you exhale, and laying eggs, lots of them.
Even without doing the math, it’s easy to see how this can turn into a big problem very quickly.
