It’s very unlikely to catch lice from objects. Lice spread primarily through head to head contact, like hugs.
If you want to do something to be 100% sure:
- Wash all your bedding in hot water.
- Put all your combs and non-washable item in the freezer for four hours or bag them up for two days.
- Vacuum the headrests of your furniture and cars.
- Most importantly, tell your friends, family and your kids friends’ families to get checked. If it comes back, it will probably be from them.
