We do not send kids home the day we find out that they have lice, live bugs or not. We do ask that they be treated and that by the time they return to school, they be live-bug free, but can have nits, as long as the nits are 1/4 inch from the scalp or further. If they do return (without a parent) without having followed those directions, we don't send them home. Parents know this and do nothing about anything. My own 3 kids all got lice at sleepaway camp last year. I bought something from FairyTales Hair Care - a kit that contained shampoo, conditioner and leave in spray. The active ingredients are tea tree oil and rosemary. I don't know if it works 100% because my youngest daughter caught lice AGAIN in the Fall, but none of the rest of us did, but her case was very, very light (I only found 2 bugs and maybe 10 nits in the second case). You have to do the bedding, the couches, the cars, the carpets, the toys, the towels....it's soooooo much work when a kid gets lice. And yes, African American kids can get it - in my youngest's class, the child who started the infestation was AA.
