You are not alone in your own skin. Millions of microscopic creatures live there too. Our skin is home to entire ecosystems of microscopic life. Bacteria and fungi get most of the attention, but mites are there too. Among the most common are demodex mites, tiny eight-legged relatives of spiders that live inside hair follicles and pores, especially on the face. Almost all adults carry them.

In this episode we explore what these microscopic housemates are actually doing on our bodies and why the idea of them can feel so unsettling. While demodex may be harmless, there are plenty of other mites that can cause problems, from dust mites, to scabies.

Hosts Katie Edwards and Dan Baumgardt turn this week to Alejandra Perotti, professor of invertebrate biology at the University of Reading, who studies the relationship between mites and humans.
