Hi N.,
I have been a hairdresser for 20 years and I have dealt with this before. This is what I have learned.
1. Make sure you wash your linens in very hot water. If they can't be washed in the hot cylce, wash them in the warmest temp you can. The hot dryer should do the rest.
Lice need blood to survive, and they will not live long without it! And, it is totally false that lice will jump from one person to the next. They CAN NOT do this.
2. Pillows (and anything you can't wash in washer) Put your pillows in a grabage bag and close it very tightly and leave them for a couple weeks.
You can also buy spray for the mattresses and couches. Make sure you dump the vacuum bag/cup as soon as you are done vacuuming.
3. You can put the hats in the dishwasher if you have one. If you don't, you can also put them in a garbage bag for a couple of days.
4. You may be itching form just thinking about it(your mind playing tricks on you. I am itching now just writing about it!)! I know when we were at work and we had a lice case, we would all start ictching after that. About the pimples, you may want to see the doc about that. You could be having an allergic reaction to the bites or the medicine. In my 20+ years of hairdressing, I have never seen pimples.
Good luck to you and I hope this helps. My son is 17 months old and I dread him coming home with lice when he starts school, but so is life and you deal with it, no matter what it takes, right?
