1. OTC Lice shampoos don’t work. Head Lice are resistant, and they might be toxic too. 2. Vacuuming your whole house doesn’t work. Head Lice are only on your child’s scalp, where the entire human head lice life cycle takes place. 3. Bagging of cherished stuffed animals and clothing and bedding is ineffective because inanimate objects are too cold for head lice to hide on. Education and Treatment are our two primary goals at NitWits.
