Just for the record, I'm okay with cute little bugs or spiders. I don't kill them. But it's those pesky roaches. They scare the bejesus out of me. I used to live in an apartment a long time ago that was filled with roaches thanks to the hygiene habits of the previous occupant. I woke up after my first night there to find a cockroach defiantly standing on my alarm clock! Then I found one in my shoe. That was it for me. I hightailed it out of there and went home to mommy and daddy. Even after the landlord exterminated I had issues with roaches all night long. It was sick and scary and I lived alone.
Today I feel more of a live and let live when it comes to insects. With one caveat. I will kill anything that can harm my children. Bees, brown recluse spider, black widow, etc. Once they are in they house they cross the line and they'd better behave or it's back to the ether they go.
Our daughter is so desperate for a pet that she actually caught a spider and put him in a special bug jar, with holes, and was caring for it until it died. she also brought home a beetle from a class project at school and we kept that little guy alive for more than a week before something untoward happened to him. I think our housekeeper threw him out
