Lice symptoms explained. After 4-6 weeks of lice infestation a rash on the back of the neck can form. This rash is often mistaken for lice bites, however it is not live bites. The rash is an allergic reaction to either louse saliva, louse anticoagulant, or louse anesthetic. Parents often ask can you have nits but not lice? If you have nits, you must have had a louse in your hair. However, sometimes parents will apply a pesticidal lice treatment and that one louse will get killed, but the nits will remain.
