Hello and Welcome to HCM,
Thanks for writing to us.
continue using vinegar And olive oil.
Wash all of your sheets, towels and dirty clothing in hot water. Dry in a very hot dryer. A thorough vacuuming of your carpet and furniture will only take a couple times since lice
do not live long without a host. Also remember to clean the upholstery in your car.
Help educate your child to not use other children's combs or brushes and not to wear other people's hats. Practicing these healthy habits will help to prevent the possibility of spreading these pesky insects.
Hope this helps you.
Wishing you good health...
