Yes, if you need to take out a nest, this is good advice. Honestly, I leave them alone for the most part unless they want to build a nest too close to my door (they get on my front porch a lot). Otherwise, if they are outisde, I don't worry about them. Any kind of bee is fine too, and even yellowjackets don't bother me. I did have those nasty red hornets build a society in the soffit behind my back door's light fixture once - that got ugly! The nest was huge and those guys are mean and aggressive. They had to go.
