I had a nest above my front door. They wouldn't even spread their wings when I came home but if anyone else was with me they got agitated. They would attack anyone who wasn't with me.
I thought I was the only one. Quite a few years ago while working on my car I noticed a yellow jackets nest inside my garage. Being a bit of a procrastinator I put off destroying the nest. I guess they eventually got to know me and didnt become agitated when I was around but if a stranger showed up the wasps let them know they were there. To bad it only lasted one summer. What a concept pet wasps. I wonder if you could train them to get the paper.
