Peace Treaty with Spiders

I have known a lot of spider-killers in my day, and I wonder if they realize what good creatures spiders are, taking care of the little bugs for us. I have a peace treaty with spiders. If they are non-poisonous and stay out of the way, live and let live. The only spiders I would kill would be the brown recluse or black widow, which can cause immense suffering to human beings. I look for the hourglass mark, the sign of the black widow. I've found them on rare occasion in the garden. Poisonous spiders seem rare overall. The recluse really is a recluse, after all. However, spiders become annoying when they build webs in the hallways or living room. If spiders can't abide by simple household rules, they have to be ejected to the outdoors.

I saw a centimeter-sized specimen crawling along my wall this afternoon near my water pitcher. The thought occurred to me that perhaps I am not the only user of my water pitcher. I wonder what the water requirements of a spider are. Probably a sip once a month suffices. Upon reflection, I'm not willing to share my water with a spider. I think my open pitcher must be retired. It can be used to water plants, but not for human consumption. Live and let live does not mean we share water together.
