No I haven't I don't even kill spiders or wasps whereas most people I know do. I actually catch them spiders in my hands and use a glass jar and a piece of vard to get teh wasp once it's landed and then put them back outside, I see no reason to kill them.
This is what I do. Except I won't generally touch spiders, I either move them with a jar/paper or just leave them where they are and avoid that part of my bedroom. The only time I've deliberately killed a wasp was when it wouldn't get off me and stung me three times before I swiped it off and squished it accidentally.
I will, however, kill flies and mosquitos. Flies because they get totally out of control otherwise and tend to get so bad they literally land on your food as you try to put it in your mouth, and mosquitos because they're vicious bastards. I still have a huge black circle on my leg from where one bit me.
Other than those two, I love all living things and try as hard as possible to avoid harming them. I even rescue snails off the footpath/road when it's raining.
