Doctors are warning parents to be careful of head lice when shopping for Halloween costumes.
A lot of people are trying on those masks, wigs and hats in the store and could leave the bugs behind.
Doctors suggest wearing a swim cap or wig when trying on a costume.
Once you bring it home leave it in a sealed plastic bag for 48 hours to kill any lice.
And if the costume is dryer-friendly — throw it in on high for 45 minutes before wearing.
