You can get lice by sharing clothes, hats, helmets, combs, brushes, hair accessories, backpacks, to name a few. Lice do not jump, fly or swim, they can only crawl. They can survive for only one to two days away from a human head. Lice need to actively feed on human blood in order to survive. Lice crawl from person to person or from an object to a person. Because children are often in close proximity to one another during activities or in classroom settings this gives lice many opportunities to move from one head to another. Lice Crusaders services are not limited to children, unfortunately head lice do not discriminate. You might discover lice on yourself. Lice Crusaders will help you too.
