Scientists at the University of Cambridge have discovered a chemical coating that stops bugs from crawling up walls.

Insects cling to smooth surfaces because the pads on their feet secrete a special emulsion -- a mix of oil and water that acts like glue. Insectislide is a special chemical polymer that absorbs the water, leaving just the slick oil on their feet. "They start slipping on their own foot sweat," said one scientist.

So instead of seeing a cockroach climb up your wall, you'll have a thousand of them on the floor going, "Holy shit, that is sooo fucking cool!"
