My domestic helper tells us that they are worms? Usually hang on walls but will cause extreme itchiness when your skin comes in contact with them. She normally takes a broom and vigorously dusts them off.

Not too sure about hygiene as all the dirt from the ceiling will fall them on all appliances, kettles, utensils. So will wash everything after that. Not that bright in the brains department but hey, I am not in charge of the domestic department
