Spiders everywhere

I HATE spiders. Now my TT has these little spiders living in it. I don't know where we could have picked them up. There are lots of them. I tried spraying around the floor and corners with spider killer, but that didn't take care of it. I'm thinking about fogging the TT, but it's a relatively small closed-up area and I'm wondering if it's safe. Cooking, eating, and sleeping areas are all right there, ya know. Fog or no fog?
