Bed bug domino effect

How does the spread of bed bugs become so rampant? Let's look at this scenario. Let's say that you have an infested mattress and you decide to get rid of it and have your house treated and then buy a new one. You go to the store and pick out your mattress and they deliver your new one and take the old one. Now the truck that picked up your old mattress is infested with bedbugs, and the new bed that they are delivering to the folks later that afternoon will get infested. So they then sue the mattress store who in turn replaces that infested mattress and in the mean time they throw away the old one. Along comes a guy who sees a new bed and mattress in the trash and throws it in the back of his truck and takes it home. Now that poor guy has been infested. All the time the children of these three families are going to school with bedbugs in their schoolbags and transferring them to the locker area where other children's schoolbags are infested. It's a vicious cycle that needs to be broken.
