That would take a lot of resources though. We'd have to be able to like successfully gather enough laborers to do that work. Although i guess if the world was in a giant bug crisis most people would be willing in the first place.
I actually have no idea. I wouldn't know if size has anything to do with immunity to chemicals. It would depends on the situation. Or i have a better idea, just get a GIANT shoe. I don't think it can build immunity against that~
I love them all. I'm never really scared of anything, unless it has to do with bugs. Psycho axe murderer? Give it a hug! Flesh eating zombie? Keep it as a pet! Hostile alien? Become it's bff! An ant or a cricket? RUN FOR YOUR LIFE
