American Homes Double as Bug Retreats

Here's a new finding that suggests no amount of housecleaning will turn your home into a bug-free oasis: More than 600 types of insects, spiders and centipedes live in most American homes.

Researchers arrived at that startling number after analyzing bug DNA in dust samples collected from more than 700 homes across the continental United States.

Study participants swabbed some dust from the top of a doorway inside their house or apartment. The sealed swab was sent to the researchers, who then used DNA analysis to identify every genus of bug DNA found in the samples.
