I catch most things and take out if I can. But wasps are only let out if it’s easier than trying to catch them. Wasps kill bees and are evil little creatures. Bees are lovely.
Along with the birds they are the highlight in the garden.
I'm allergic to wasps. Which is odd because I don't have the same reaction to bees. Though I guess someone could tell me the difference. I will admit I kill wasps, and scorpions. Bees, they are just happy little dudes who are actually surprisingly easy to catch and release.
