The natural environment of the Booklouse is usually in and around animal nests, tree trunk crevices, and under bark. They are also often found living in warehouses, granaries, museums, and other food manufacturing facilities.
In terms of reproduction, some species can reproduce without fertilisation. A typical female Booklouse can produce around 200 eggs, typically laid at a rate of one to three per day. Eggs usually take up to two weeks to hatch, with the emerging nymphs taking around 15 days to grow into adult booklice. The adults are moderately well-adapted to their environment and typically have a life expectancy of up to six months.
