I was confronted with a similar situation quite a few years ago. But the biggest concern in my case was "Black Widow" spiders. There were tons of them! So what I did was to toss several "Bug Bombs" (Self releasing spray cans from Home Depot) in ahead of time, (at least 24 hours prior), and then I dressed like an astronaunt, as previously mentioned, and then crawled under there and "Cleaned House!" Go for it! If I can do it, anybody can!
Good luck, and please show us all of the "Keepers" you come home with.
