I'm too empathetic to kill bugs, even ones I hate, like stinkbugs. In the case of spiders, I tend to ignore them and let them be, though I'll sometimes let them outside if people I'm living with are threatening to kill them. Most bugs, I can handle with my bare hands, but because some spiders are defensive and aggressive, I usually go for a cup and trap them that way as I relocate them outside. Lessens chances of me hurting them as well.
