Psocids (pronounced so-sids) otherwise known as booklice are tiny grey/brown insects between 1-2mm long which can be found in or around dry foods such as flour, sugar, semolina and powdered milk.
They are not caused by poor hygiene and are just as common in clean homes both old and new. Their preference is to live in dark, warm, humid places e.g. folds of packaging in food cupboards - they dislike light and disturbance. They feed on a variety of food, such as flour, and live for approximately 6 months during which time the female may lay up to 100 eggs.
As psocids prefer areas of high humidity they are often found in kitchens where fitted cupboards and food products provide the moisture and darkness that attracts them. They increase rapidly in warm conditions so summer/autumn is the time of year they are likely to be discovered.
