How many bugs are living in your home?
Here’s some new research that will make you go ‘ewwwwwww.’ More than 600 types of insects, spiders and centipedes live in most American homes. That’s according to a new study from researchers out of North Carolina State University and the University of Colorado Boulder.
Researchers determined that large number after analyzing dust samples collected over 700 houses all over the United States. Study participants were asked to collect a small sample of dust from the top of a doorway in their house and send it to the researchers in a sealed package. The researchers then analyzed the DNA in the samples to determine the range of bugs in a typical home.
“That’s an incredible range of diversity from just a tiny swab of house dust,” said study author Anne Madden in a press release.
The researchers did find three variables most affected how many insects were present in any given dust sample. Not surprisingly, homes with the most insects included: rural homes, homes with a basement and homes or apartments with a cat or dog.
“We were surprised to see that these three variables — which we have some control over — were more powerful predictors of biodiversity than climate,” Madden said. “We had expected environmental factors associated with regional climate to play a larger role than they actually did.”
“We all live with an abundance of normal flora consisting of bacteria on the surfaces of our skin and within our intestinal tract,” he says. “That relationship is a co-dependent one as these bacteria are necessary to help with digestion and may even supply much needed vitamins. The world outside our bodies also consists of many bacteria and other organisms which we never see and likely have little effect on our daily lives.”
Whether good or bad, you’re not alone in your home!
