Control on clothing and bedding:
(1) Wash bedsheets and pillowcases frequently (at least weekly) in hot water (>= 55°C).
(2) Cover anything that cannot be cleaned regularly (mattress, quilt and pillows) in impermeable covers.
(3) Wash nightclothing in hot water (>= 55°C) regularly, especially in winter.
Control in the environment:
(1) Replace carpets if possible.
(1a) Use a wooden, linoleum or other solid floor covering.
(1b) If unable to replace carpet, treat regularly with acaricides or tannic acid. Unfortunately a patient with allergies may react to acaricides.
(2) Replace any upholstered furniture with wooden or leather-covered furniture.
(3) Minimize objects that can accumulate dust.
(4) Keep the house as clean as possible and free of dust.
(4a) Minimize dust dispersal while cleaning.
(4b) Use a vacuum cleaner with a HEPA filter. Filter bags should be extra thick to reduce dust leakage.
(5) Soft toys should be either washed in hot water (>= 55°C) or frozen.
