House dust mites are present in all homes in the UK. They are microscopic insects that live off human skin scales and form part of the dust in our homes. The climate and conditions inside our houses are ideal for their survival. They prefer bedrooms - in particular, beds and bedding. This is where we shed dead skin cells for them to feed on, where we sweat, providing them with water, and where the warmth sustains them and allows breeding.
