I'll always trap and put a spider outside rather than kill it, and even open the doors and chase flies out.
The only insect that gets it in my house is wasps, because my OH loathes them and I'm scared the cats or my baby will be got.
I was at my father-in-laws not so long ago and a moth had got in. I calmly walked up to it, scooped it in my hands and took the fellow outside.
( I was informed by a post somewhere that I may have harmed it doing that, but my intention was good ).
No point in killing if you don't have to.
That gravestone thing sounds absolutely lovely Leigh, you big soft girl.
