How is Demodex Spread? Demodex mites have very short legs and can move up to 8 to 16 cm per hour. Fortunately, they cannot fly. So how are these small, slow-moving Demodex mites so contagious? The answer is simple: Demodex mites do not have to move to a new host; instead, they wait for a new host to come to them! Where do they wait for the new host? • On towels, sheets, pillowcases, combs, and other personal items. • On the host's face, hands, and body - when you shake hands or have close physical contact with them. • On beauty salon equipment • On the headrest in public transport Demodex's birth rate is relatively high, and since it is too small to be seen, you do not know what surfaces it is on to avoid. That’s why you should observe your personal hygiene and don’t use other people's personal items.
