You may think your home is sparkling clean. But even a clean house harbors a host of small creatures that have a fascinating web of interactions with each other and with the humans who live there.

What do you know about the ecology of your home? How does the dust that accumulates in the corners before you vacuum affect your health? Are there any advantages to cleaning less often?  If you have ever wondered about the fungi in your shower, the bacteria on your soap or the camel crickets hiding out in the basement, call in your questions.

Never Home Alone:

Dr. Rob Dunn has written about the wilderness thriving in our living spaces in his book, Never Home Alone. He will tell you why you shouldn’t overdo on the home hygiene and help you understand how to welcome our unseen guests safely.

    I live in a southern state, and during the spring and summer there are always chameleons that get into the house as we enter and exit. We just can’t keep them out. They frighten me when they jump out unexpectedly from a potted plant. I called what I thought was the game warden to remove them but instead the Sheriff came saying that we have no game warden in this county. It’s his job, he said. The chameleon hid, and the Sheriff couldn’t find it. After that, I learned that I could spray ice water on them, and they will go into shock. Then I can safely sweep them out of the door. The glue boards used to snag pests are too messy and inhumane or (in-animal-mane). My brother suggested I make friends with them and give them names. That didn’t work. We are still enemies.

    I’ve lived to a ripe old age and never worried about microbes, etc. It’s my belief that it is never good to be “too clean!”

    I live in NY state, and we have the rats that are frequent visitors. I do my best to keep clean.

    Thanks for this–Dr. Dunn’s book is great–my husband and I just read it, and neither of us could put it down. The book will join our permanent library for re-reading. We were lucky enough to participate in some of the studies that he writes about as “citizen scientists!”
