Sounds quite familiar! I also did this with my child. I put lice shampoo in my child's hair, covered it with a shower cap, but I waited overnight, I washed his hair the next morning and combed with a lice comb. This really does work. I also talked to a lady from my local Dept. of Health and she told me that you don't have to buy all of that expensive stuff for your furniture and bedding. Just wash the bed clothes in hot water, dry them in the dryer, vacuum the furniture and the mattress, and you should be ok.
