Personally I had a spare bedroom that I basically turned into my new bedroom and abandoned the old one. This seems to be working great as it seems I am getting no new pin prick biting which means no new straggglers are on me. It also helps me stay away from everything I was touching on a regular basis. You can also buy washable keyboards for your computer they are really cheap like 15$. Covering and sealing everything is great to do before you treat then dont touch for 2 weeks. Why risk the risk of reinfestation.

Two weeks should be a significant time that would kill off all the scabies mites that mite be living in your home environment. Anything longer than this isnt necessary. I do suggest during that time you make sure you get a complete kill on the scabies mites that are living on your body. After this you should no longer have to worry about getting reinfested. Scabies can only live off their host for about 3-7 days maximum, the other 7 days would be insurance as some cases reported the scabies mites could live longer off the host if in the rite breeding temperature and conditions.

If you have lots of space just set up your living area in a different area of your house for a week or two until you know you are not infected, this will give you a chance to clean up the area you lived in before scabies. Post scabies itches alot like scabies but you should always keep up the cleaning and stuff to avoid scabies reinfection. Keep an eye out on your feet and hands as this is the primary spot for reinfection. Avoid touching people also

If you are well off I would seriously consider moving if you live in like a condo or apartment, from my experience these things can be pretty nasty to get rid of. Or you could just like temporarily move out for a few weeks and treat yourself and then your environment should be fine.
