Will head lice live in an empty bed?

Head lice cannot survive long without a human host, as they rely on blood for nourishment. They typically live on the scalp and hair, making an empty bed unsuitable for their survival. While they may occasionally fall off a host and end up in bedding, they will likely die within 1-2 days without access to a person. Therefore, it's unlikely for head lice to live in an empty bed for an extended period.
