Ovide
"Ovide is the best thing ever! 4 years ago and after a crash course in head lice the Dr prescribed RID. After 4 months, countless hours combing, washing clothes and $500 later to treat 4 children and the sprays for furniture, every week these roaches kept coming back (this amount don't include the extra expense that we incurred replacing clothes that finished in the garbage can after being washed in hot water). Finally I went back to see my children's Dr. and she prescribed Ovide. After the first treatment, no more head lice! 3 months ago my son got them again and off course my choice was Ovide hands down! Don't waste money on other products."
