An informative, eye-opening exploration of creatures living in our homes and bodies. The good news is that not all of them are bad. While pathogens are harmful, other species are beneficial to us—spiders are my new friends. Dunn explains and emphasizes the important of biodiversity. He encourages us to invite bacteria, fungi, and insects back into our lives instead of getting rid of them. This book has validated my decision for turning down services that wanted to exterminate all the bugs around our house. I am also going to stop using disinfecting wipes, which kill 99.9% of viruses bacteria including the good ones. Although I struggled to finish the book because of my own lack of interest on scientific writing, I am glad I made it through. I have learned a ton about our little friends I didn’t know I had living with us.
