About scared to death!!!

At first, after finding a black widow spider in our water meter box, the husband & I about fell over from shock. Neither of us had seen one up close & personal before, only heard about them! Instead of killing it, I did some online research to findout the truth about these things and since, if you are a healthy adult it can't kill you because it doesn't release enough venom into your body for that and because they tend to stay by their webs & not bother anyone, I'm going to take the road of leaving the thing alone for the time being. Besides, they kill bugs. The one con I can think of against the spider though is that well, she is a female & will lay eggs.....do we really want more of these spiders around? Maybe I can find a park or natural resources place that will take her & give her a home. I don't want to mess with it!
