House dust mites in Bristol

Abstract
Summary: A survey of bedding in Bristol revealed reducing mite concentrations on children's toys, mattresses, overblankets and pillows.Dermatophagoides pteronyssinus was the commonest mite found. A vacuuming schedule was devised for removing mites so that a double blind trial could be carried out. Investigation suggests that even with expert utilization of efficient vacuum cleaners the clinical efficacy would be limited as the mites appear to rapidly migrate back into the bedding.
