Friends - I was in my hangar yesterday and suddenly, out of nowhere, a swarm of bees flew in and showed particular interest in only one spot on the plane's wing. I've never seen bees in or near the hangar before. Obviously there's some lubricant, or something else, at that spot on the wing (near the flaps) that attracted the bees. I did not stick around to see what was there, but want to address the problem going forward. Can anyone recommend a good bee repellent? Do those sonic devices work? I don't want to start spraying chemicals to kill honey bees (and possibly damage the plane), but if anyone can give me some ideas on how to "discourage" bees from visiting the hangar, that would be appreciated. Thanks!
