I am the type who re-locates rather than decimates...I quite like spiders. My stepson has extreme arachnophobia..many is the time we have had to rescue him from our eight legged friends. He was driving to work one day and actually abandoned his car (some distance away) and walked home for flyspray...I told him the fumes from the spray were probably more dangerous than the spider but he wouldn't get back in 'til the spray did it's job.
