This is one of the biggest hurdles we face as bee keepers. Most people don't know much about how many different bees and hornets and wasps there are. So our bees are just a big unidentified threat to them because they STING.
Thanks so much for your answer Whispers! I'll keep until fly's with all necessary.
Thanks jbraun. I think the language it's important too to understand. Here in Portugal "Bee-kepers" are translated as "Apicultores" (it's like a specialised word for a job like teacher) even the word bee isn't clear (abelha=bee).
Im not a specialized bee-keeper, I came from big city most people don't understand nothing about bees, in my "High School" they had hives but no-one explained us how they work and how they keep them, even the closest employes. "The ideia that it's a hard thing". But who want's to know need's to research, and who want's to do right learn about the errors.
But I'm surely want to have hives like a hobby in the future. But I'll research many as I can. I just committed a error but I'm not afraid to be sting I never was (at this time). I run a "alternative-media" website here, I appreciate truth and I'll regard your usefull suggestion that give me some "inside" ideias to run articles about the theme and things that people doesn't understand at all.
P.s: I transferred the wasp to the new more clean and organised place. https://youtu.be/JpgfFDxxbp0 like on this video but in a small plastic box, with a outside entrance. I'll post a picture next day with sun-light.
