It really depends on your school policy on whether or not they can even send your kid home with lice eggs. Since lice eggs don't move, most schools have the policy that the kids with them can stay in school. However, this year, as parent reps, we made our school adopt a new policy that states that a student with eggs can be sent home. I know that that might sound extreme, but after you have worked so hard for weeks to get rid of them and the student right next to your daughter who keeps them gives them to her again, you get so mad!!! It isn't the child's fault, but we are trying to make the parents take some responsiblitly in getting rid of the critters!! If the kids are there with eggs, then eventually they are going to be there with bugs. Most parents don't want to miss a lot of work being called out for lice detail and will get something done about the problem.
Now when you get down to the other 5% that the parents just don't care ~ there just isn't anything that the school can do. You can not make the parents do it. We do in-home visits and show the parents how to get rid of them, but the rest is up to them. They get free product and hair checks and NOTHING does any good. All I can say is that if you know of someone that has head lice all the time at school, go to the teacher first and request that your child not be place in a seat around that child. If that doesn't work then take it to the principle. Always remember the child's feelings though. They just can't control what their parent do ~ it is sad! Especially for the little girls that can't have their heads shaved!!
