I'm sorry, I'm "completely duh" on what you mean, or what your question is implying. If you'd care to to explain, I'll be glad to reply.
We try not to kill anything, as both my hubby n' I believe that 'everything is part of everything'...but I'll be first to admit, I have drowned a couple of those huge hairy spiders that crawl up the basement pipes and end up in my bathtub (rather than capturing it and releasing it). We 'kill' (by pulling) some of the weeds in our garden, but at least they go into the mulch pile to replenish the earth.
