I had tiny pea-sized spiders stop, turn towards me, and lift their lil feetsies, for combat. Shoulda killed the fuckers, just to cull that kind of ridiculous level confidence. Couldn't tho. Too cute. And a bit scary.
If spiders could keep bugs in check, there would be no more bugs. It's only so much spiders can do, but I do appreciate their effort, sincerely. I would always let them stay if they kept to the ceiling corners.
