Question: how long can lice live in freezing temperatures?
Answer: Lice cannot survive, off-head, more than 24 hours. Lice cannot survive extreme heat or cold temperatures. Lice can hold their teeny little breath for up to 8 hours. Lice have short legs with claws at the end that allow them to expertly hang on to the hair shaft - even in wind, the pool, and during hair washing.
