My best advice is from an Japanese guy who taught me .He is a Veteran Uber driver in L.A. and it worked for me like an magic.
It's Lemongrass oil.
It smells good and it takes care getting rid of that nasty critters from your body and also kill them at same time.
Put drops of that oils into your shampoo & conditioner too, then put on your palms & rub it all over your body after the shower . Make sure wash your clothes in hot water and put it in hot heat dry. Clean your house, bedding, garage and yes, your car interior too.
Good luck.
