Probably not to your level, but I do avoid killing bugs. My husband showed me an easy way to get rid of flies in the house. You just turn off all the lights, then let the only light come from the door to the outside. Flies are attracted to light, so they’ll all congregate at the door, and when they get there, you can simply open the door & they should fly out.
I especially try to help out spiders.
To keep myself honest though, we have Orkin pest control and many ants have lost their lives from this.
