Can lice and nits on items bagged survive cold temperatures?

Lice and nits (lice eggs) can survive cold temperatures for a limited time, but extreme cold can kill them. Bagging infested items and placing them in a freezer for at least 24 hours is an effective method to eliminate lice and nits. However, if the temperatures are not sufficiently low or the exposure is too brief, they may survive. It's generally recommended to wash items in hot water or use freezing as a complementary method for thorough lice control.
