I've been exposed to lice, how long until I get them?
I have been exposed to head lice, how many days before I know if I have them?
There isn't a specific number of days after exposure to head lice that one will contract the pests. In fact, exposure to lice doesn't necessarily mean that you will contract them yourself. If you were expsoed, we would recommend daily head checks for 10 days. If you do not find live lice or nits (head lice eggs), it is safe to say you are in the clear and treatment is not necessary.
