| The common house-dwelling booklouse is wingless or its wings are reduced to small scale-like, non-functional wings. |
| Sweating and high humidities may form in wall voids when new lumber becomes enclosed, encouraging booklouse outbreaks. |
| I think of all that precious, friable, impermanent, and biodegradable paper and what certain species like the booklouse, the silverfish, and the cockroach might want to do with it, not to mention the lower forms of life. |
| The indoor ones, such as the booklouse are wingless, and can scrape away at books and other organic material. |
