The best way to control booklice is to eliminate moist environmental conditions. Reducing the humidity in your home will eliminate the mould on which the booklice feed. Clean the infested areas thoroughly, if possible, vacuuming all surfaces and cracks/crevices etc.
Taking as many objects as possible outside and drying them in the sun on a bright day. Under no circumstances should toxic pesticides be used to treat your home as it will just give you a short term relief. Remember that, sanitation is the best approach to eliminate this pest without any harmful chemical.
