the only animals or insects that really scare me or gross me out are ticks and mosquitos and wasps. those animals dont deserve to exist. they are the only actively malicious insects i encounter on a daily basis and i hate them all. i think i'd forgive killing any of those guys.
they aren't malicious, that's just what they do. especially wasps, which don't even bug you if they don't feel threatened. ticks and mosquitoes, I don't like to do it, but I do kill them. they carry disease that can kill people and people > them. flies too but similarly to you I don't have a big fly problem
moths and ants and things like that I just take outside. usually I leave spiders where they are unless they're one of the, like, two species that can actually hurt people here, and in that case I'll take them outside too
