Does Mouthwash Kill Lice And Nits?

Yes listerine the original kind does kill head lice. You put it in a spray bottle and leave on for two hours you can add a spray off vinager during the last 30 minutes then was hair with a good shampoo. We use denorex then condition with a coconut conditioner and comb.

Hi I'm 11 and I have lice my mom said to use Listerine so I did but before  I did I looked it up  and  and it said to soak it then put your hair in a cap or a store bag  and then let it stay on for 2 hours then comb it out then when you wake up wash it out is that true I don't know that is y I'm asking you and trying it out on the same time so is it true?

No, it would be kool if it did, but it doesn't!!

Olive oil in your hair, place a shower cap on. Leave over night or at least 8 hours.  That will do the trick.

It can work, but the best thing to do is to rub mayonase in your hair and leave it on for about 2 hours and then check your hair. If needed to, you can keep rubbing it with mayonase until the lice are gone.
