I don't like to kill anything for any reason, but sometimes needs must.  My general rule is that so long as you stay out of my personal space, you can live.  If a bug crawls on my and I slap-kill out of reflex, I apologize.  If ants invade and I have to bring out the bug spray, I apologize.  I prefer to take individual bugs outside if I can (and let the house gekkos and feral cats eat 'em).

That is a fair rule. Mine is similar: if it's actually attacking me, I will defend myself. That mostly means that mosquitoes and other biting insects are fair game if they land on me. If we had a home infestation, it needs to be handled. But an ant on the sidewalk or a spider just chilling in it's web? They can stay (though indoor spiders are moved to the garage or shed).
