Mites
Mites belong to the arachnid family and are normally found in every household. They like warm, humid environments and feed on skin flakes. For this reason, they are often found in mattresses, upholstery and sofas.
They reproduce very quickly. Having mites does not necessarily mean that your home is dirty. It is almost impossible to live in a mite-free environment. However, it is possible to significantly reduce their numbers.
