Sarah Casello-Rees of Rapunzel's Lice Boutique knows head lice.
Casello-Rees recently shared information with Patch about preventing and treating head lice, along with these buggy facts:
- Head lice will not infest your home. They can only survive for a short period of time without a host; at most, from 24 to 48 hours.
- Itching is an allergic reaction to the louse’s saliva. Most people–about 60 percent–are not allergic.
- A female louse can lay around 6 to 10 eggs (nits) per day, which hatch in about 7 to 10 days. It takes the newly hatched louse another 7 to 10 days to mature and reproduce its own eggs.
- Dried up lice and their nits have been found on the hair and scalps of Egyptian mummies.
- A female louse only needs to mate once and can continue to lay viable nits for the duration of her lifespan.
- Head lice can infest anyone, regardless of personal hygiene. They prefer clean living environments just like we do.
- A louse can hold its breath for up to 8 hours.
