They could be any shade from yellow to brown to gray. Booklice are able to consume microscopic food particles thanks to their long, thin antennae and specially designed mouthparts.
How common are booklice in indoor environments?
Eine Studie von Kawakami et al. published in Urban Pest Manag Journal in 2014 focusing on insect dispersal within Japanese homes, conducted an entomological survey on 20 residences in Tokyo over the summer and fall of 2011.
House dust samples were collected from the floors of living/dining rooms and bedrooms using electric vacuum cleaners, and the number of arthropods in each sample was quantified.
House dust mites topped the list, followed by booklice (Psocodea). This means that booklice are a common household pest. And the most prevalent species of booklice indoors is Liposcelis bostrichophila (Psocodea).

Booklice can be a significant sensitizer for asthma patients
Recent studies have indicated that booklice are a significant indoor pulmonary allergen. But where can booklice be found?

Using tatami mats or carpets in bedrooms was similarly associated with the amount of this protein in the blood, consistent with the findings of an environmental investigation that examined the occurrence of booklice in houses.
In addition, approximately one-third of patients who were allergic to booklice had a specific allergy to this insect, as opposed to an allergy to other insects.
Lip b 1, a protein implicated in this specific allergy to booklice, was discovered to be a new protein with an unknown function.
In a number of nations, including India, China, Iran, France, and Spain, booklice have been detected in houses and have been associated to respiratory allergies.
In a research conducted in Beijing, China, booklice were discovered in almost fifty percent of residences. 25% of house dust samples from patients with respiratory allergies in Mumbai, India included booklice, and 20% of patients with respiratory allergies were found to be allergic to booklice.
There have also been examples of persons developing asthma or allergic reactions after being exposed to booklice in the workplace or after consuming infected oats or rice.
Other varieties of booklice, such as Liposcelis decolor, L. corrodens, L. entomophila, and L. pearmani, are frequently found in indoor environments and are thought to be allergens, although their allergenicity has not been researched.
