I dig peppermint oil, will try that out next summer. Thge wasps in Leeuwarden were ticking differently than others I had encountered previously. They were aggressive and outright audacious, maybe they have a thing for apples. Never thought an apple would be a better lure than sugary liquors but it was, by far! You just really have to make sure that the apple is nowhere where people would step on, especially at night. It would be a horrible horrible experience disturbing their crawly-munchfest with a foot ;)

thanks for sharing your take on this <3
