At night, these parasites crawl onto your bed, bite you and    suck your blood. Then they find a nearby hideout where they    leave disgusting telltale signs. But these pests have an    Achilles heel that stops them cold.

    Adult bed bugs are about the size and color of an apple seed.    After biting, they hide in a nearby cranny, like the seam of    the mattress.  
    At the University of California, Irvine, biologist and engineer    Catherine Loudon is working to create synthetic surfaces that    could trap bed bugs. She was inspired by the tiny hooked hairs    that grow from the leaves of some varieties of beans, such as    kidney and green beans. In nature, these hairs, called    trichomes, pierce through the feet of the aphids and    leafhoppers that like to feed on the plants.  
    Researchers have found that these pointy hairs are just as    effective against bed bugs, even though the bloodsucking    parasites dont feed on leaves. Loudons goal is to mimic a    bean leafs mechanism to create an inexpensive, portable bed    bug trap.  
    You could imagine a strip that would act as a barrier that    could be placed virtually anywhere: across the portal to a    room, behind the headboard, on subway seats, an airplane,    Loudon said. They have six legs, so thats six opportunities    to get trapped.  
    --- Where do bed bugs come from?    Bed bugs dont fly or jump or come in from the garden. They    crawl very quickly and hide in travelers luggage. They also    move around on secondhand furniture, or from apartment to    apartment.  
    --- How can I avoid bringing bed bugs home?    It would probably be a prudent thing to do a quick bed check    if youre sleeping in a strange bed, said Potter. His    recommendation goes for hotel rooms, as well as dorms and    summer camp bunk beds. He suggests pulling back the sheet at    the head of the bed and checking the seams on the top and    bottom of the mattress and the box spring.
