What tiny creatures share your home?
If you think your house just belongs to you and your family, think again. As well as flies, spiders and woodlice, there are many microscopic animals and plants living with you. No matter how clean your house is, the carpets, armchairs and mattresses are probably full of tiny animals called house dust mits. These feed on the flakes of skin that you shed every day. Before the mite get to them, these bits of skin provide food for microscopic moulds, and the mites eat the moulds along with the skin. As long as you are not allergic to moulds or dust mites, neither will do you any harm.
