Prevention - Caution children, particularly those in the lower elementary grades, against sharing playmates' hats, other clothing or combs.
Suspecting an Infestation - Itching and scratching of the head is an important symptom. If that is happening, carefully check the head of the child or other family member for nits.
Treating People - In recent years, over the counter products including store brands in virtually all retail drug outlets are safe and effective treatments when used according to label instructions. These nonprescription products often include enzymes to loosen the "glue" that attaches nits or eggs to hair follicles, as well as lice killing active ingredients. Dispensed as liquid, lotion, gel or creme rinse, they are applied to the affected area for a few minutes and rinsed out. Fine tooth nit combs are then used to comb out any remaining nits or eggs.
When lice are discovered on one individual in a family, the other family members should also receive treatment, unless it is absolutely assured that they have not been exposed.
Persistent infestations may require retreatment at 1 - 2 week intervals. Some resistance to the commonly available treatments has been reported.
Treating the Home - Methods for controlling the spread of lice are tried and true. Washable items such as clothes, bed linens and towels should be washed in hot water, at least 130° F, and dried in a hot dryer for at least 20 minutes. Non-washable material items such as stuffed animals or pillows can be dry cleaned or stored in a tightly sealed plastic bag for at least 14 days. Personal items such as combs and brushes should be soaked in hot water. Be sure to vacuum carpets, chairs and couches thoroughly. It may be beneficial to use an over the counter or non prescription lice killing spray and then vacuum thoroughly.
The Community - Lice infestations are so common that no one should be embarrassed about discovering pediculosis. Notify school authorities about any infestation you observe, so other parents can be warned and a possible epidemic prevented. Inform your child's playmates' parents as well. It is important to protect all children as well as your own.
