What is your philosophy on bug- and/or spider-killing?
I think of spiders as very good and often useful creatures (because they eat bugs, I guess), and I do my best not to mess with them. I leave them alone in my house, and if I'm somewhere where somebody wants a spider gone or is intending to kill it, I will volunteer to catch it and put it outside. It really bothers me to see them killed.
Luckily I'm not faced with any sort of bug infestation, or I might resort to killing them. I'm not interested in cohabitating with any infestation of bugs. Except for fleas and mosquitos, I try not to kill them. I had a gnat land on me the other day, and I just reached over and smooshed it. Then I felt bad.

It was a mindless action, but he or she wasn't going to hurt me.
I'm curious to know how others handle bugs and spiders in the home or other indoor areas.
