Head lice can't fly or jump, and they're not transmitted by pets. They spread by head-to-head contact or via contact with contaminated personal belongings or home furnishings.
This is the most common mode of transmission and may occur as children or family members play or interact closely together.

Less commonly, head lice may be transmitted via such items as:
- Caps, hats and scarves
- Brushes and combs
- Hair decorations, such as barrettes
