Use Hair Spray to stop them in their tracks then you have time to get someone to squish it, or just time for you to get the courage up to get something to scoop it out withWhen I lived in Korea, the spiders were huge. I would bug spray them until dead, but they sometimes disappeared. I don't know if they could survive the spray, or if they equally huge roaches took them, but I ended up putting a cup over them, just to be sure. . .
Spiders spook the life out of me.
