From microbes to millipedes: The mini wilderness in our homes

Every surface in your house, every drop of water, every breath of air you take in your home is alive.  Our homes are like habitats for bacteria, viruses  and insects.

Professor Rob Dunn studies the organisms that share our living space. He says we need to learn to live with the wilderness in our homes because many of the 200,000  species found in our houses  can benefit our bodies and going to war with them only makes them more dangerous. His new books is called Never Home Alone: From Microbe To Millipedes, Camel Crickets And Honey Bees, The Natural History of  Where We Live.
