True or false: Human Lice are not a pest control problem but a medical problem?
It is true, human lice are considered a medical problem. The reason is because these lice essentially spend all of their time on the host-head, crab/pubic and body louse. Human lice can only survive for a short time off their host, 48 hours for head lice and 24 hours for crab/pubic lice and a few days for body lice, those that are removed or fall off the host have almost no chance to infest a new host. Because of these characteristics, residual pesticide treatments are not likely to be a control method; also there are no pesticides labeled for application on humans or their clothing. Best-bet, consult you doctor. Remember: Only the body louse is a vector for human diseases: typhus, relapsing fever and trench fever.
