Lice spread during hair-to-hair contact among humans. They don't jump or fly. They are not a sign of poor hygiene, and anyone can get them. Pets do not spread human lice.
Teach children not to share hats, scarves, brushes, combs and hair fasteners.
What to look for
Frequent head scratching can be a sign. If you think your child has them, look closely at the head and hair for live lice — reddish-brown, wingless insects — and tiny eggs — grayish-white and oval-shaped. Experts advise spending 15 minutes a week checking each child's head.
To treat
The Iowa Department of Health recommends a 14-day treatment process that combines using an over-the-counter, medicated shampoo containing pyrethrin or permethrin and combing to remove nits.
Use of oils, mayonnaise and vinegar has not been proved effective. Kerosene and gasoline do not work and are dangerous.
In the home, use ordinary cleaning methods. Vacuum floors and wash bedding and clothing in hot water.
If the initial treatment doesn't work, check with your doctor. Prescription shampoos are available.
