As creepy as these guys might be they are necessary.
I have been bitten two different times by a brown recluse while cleaning our garage. The first time I was really sick, but my Dr. said that I would build an immunity. He was right! the second time was a lot less nasty, more like a bad horse fly bite and no necrosis the second time. The brown recluse is a tough one to spot, they are so small.
I love the jumping spiders, they are really curious. I had one living in my desk for a few days and when I would work there he would come out to see what was going on. He left for better hunting after a few days.
I just hate it when they crawl on you!!
