Do booklice or bed bugs pose a greater threat to household hygiene and health?

Bed bugs pose a greater threat to household hygiene and health compared to booklice. Bed bugs can bite humans and cause skin irritation, allergic reactions, and psychological distress. They can also spread quickly and be difficult to eradicate. Booklice, on the other hand, do not bite humans and are more of a nuisance than a health threat.
