And the problem is? (I also suffer from some level or arachnophobia) I ran across a spider in my garage a few years ago that had to be the offspring of Shelob. If I'd have lived in the country, it would have been shot. I would consider .22LR birdshot as a good spider load.
I don't see anything wrong with that statement. As the old saying goes "There is no overkill, only Fire and RELOAD."
I have a deal with the spiders in my area, "You stay outside my house and you will continue to live. Anywhere in the house and you die. Period. End of negotiations." Every season I remind them of this rule and every year I gleefully make an example of the interlopers.
