Every year we have several nests of yellow jackets on my property, and usually at least one paper wasp and bald faced hornet nest (this isn't wasptopia I just have acres of land). Every year I leave them alone. Every year I leave some dead fish out for them in the spring and they go hogwild over it.
Every year, I walk through grass every day with dozens of yellow jackets buzzing around in my path, and they ignore me. I open and close pen doors with bald faced hornets chewing away at the wood for their nests. Every year the paper wasps hang out by my back door where I park my car.
I have been stung once in 12 years, and it was the year I stepped directly on an underground yellow nest I had not seen yet. This nest was in a spot I walk over nearly daily, and I had only moved to the side to get around a bird that day. I had to have been walking within a couple feet of it all summer and never noticed.
And I stepped *on their home* and only received one warning sting for it.
Not even repeatedly by the same wasp!
It is very possible to live in harmony with them.
Spiders as well. House rules here are we don't kill spiders. If it's in the way I might relocate, but if there's predators then there's prey, so if I see spiders I can be relatively sure they're hunting something I want less. Same goes for house centipedes.
They're all just little guys. If they're not actively causing harm just leave them alone.
