To get rid of the spiders, I recommend that you use Demon WP insecticide. It is odorless and safe for indoor use. I live in Alabama and you cannot buy Demon in Walmart or Lowes.
I have to buy it at the farmers Co-op. It does not require a license to use, but the sale is limited to certain locations. It does a number on insects and spiders for months. Also, it does not give off fumes.
The way it works is: one packet is dissolved in a one gallon hand-pressurized pump sprayer, like you can buy at Lowes or Home Depot. Spray a small stream where the bugs nest or crawl.
Once the water evaporates, a fine powder residue is left behind. When the bugs walk across it, they get some of the powder on their feet. The absorption of the powder is what kills them.
It is the ONLY insecticide I have found that gives off no odor, lasts for months in the home (use on baseboards), and (best of all) kills spiders!
If you can get it, this will solve your little problem.
