Call me crazy but I actually find spiders to be very cute. They're just so small and have lots of big eyes. Even birdeaters are smaller than most of my pets. Then again, I do have a boa constrictor so maybe my input isn't the most valuable on that....^w^"
When I find a spider inside I usually just pick it up and put it outside wherever there's bugs I need taken care of. Though admittedly some of them I've just kept around as pets. It was storming one night a few years ago and a tiny crab spiderling scuttled across the table whilst I was sculpting a taxidermy form. Well, I didn't wanna throw out a baby spider into the rain so I made an enclosure for it and kept it. Fed it and grew it into an adult, watched it molt and everything. Eventually it died of old age but it was a pretty neat little animal.
I want another pet spider but my partner has arachnophobia and won't let me get the tarantula I want. So I'm having to settle for a trapdoor spider, instead. Oh well
