Legions of tiny bloodsucking bugs are biting their way through America, leaving unsuspecting victims with itchy bites. Bed bugs in America disappeared about the time of the rotary phone. The upside of DDT, and long-gone pesticides like it, was that it worked very well. The little blood suckers were dead as the Dodo here but they lived happily on in Asia, Africa, eastern Europe. Now they're hitching rides in luggage, shaving kits, coming soon to a hotel near you, perhaps. Or a college dormitory, or your very own bedroom.
