A group of scientists* fabricated a material with tiny hooks modeled on the bean leaf trichomes. The material was observed to snag the bed bugs, but was less effective in immobilizing them than a real bean leaf. This is an interesting idea. Perhaps with a little tweaking, a fabric for use in a better bed bug trap can be produced.
