Aerate the bedroom for at least 15 minutes per day, preferably when it’s cold and dry outdoors (humidity below 50%).
Maintain the temperature at 18°C.
Don’t allow humidity to concentrate and build up. Close the bathroom door and do not dry bed linen in bedrooms.
Pull back the duvet and expose the bed to light during day time
Change the bedding every week and wash at 60°C.
Use a bed with an open-slat base if possible.
Opt for synthetic materials where mattresses, duvets and pillows are concerned
Vacuum the house using a cleaner fitted with a HEPA filter and clean with a damp cloth (avoid cleaning with large quantities of water).
Consider treating all the places where dust mites can hide: mattresses, bed settees, arm chairs, soft toys, etc.
