I hope you eat a spider in your sleep, killing it is stupid. Spiders help kill all the mosquito's, wasps, hornets, flies, and so much more. Think twice about killing it or telling someone to kill it.
Bad spider karma dude. I have been spared a bite so many times that I could have been tagged because I release spiders from my house. I bet you are going to end up eating a spider in your sleep tonight for that comment haha.
I believe there are 2 wasp species that actually eat brown widows... And although I leave critters alone when Im outside (their world), when they come into the house (MY world) they generally die.
