Nurse told me to try vinegar as rinse left on for 20 minutes. Seems to help awhile but they come back. Have done the spraying, washing bed clothes, her clothes, shampoo and vacuum carpet, taken away all stuffed animals. I'm at my wits end. Even after I used the prescription shampoo I was combing out live animals.
Head lice are frequently a very frustrating problem.
The major symptom is itching. You may see live lice, but usually will not, because they are small, and do not like light. As you look through the hair, they scurry away. What you will see are their eggs, called nits. The nits look like little flakes of dandruff, but they don't flake away.
