Thank you all for your insight. I am pretty sure they are paper wasps, as the one I saw going in was dark in color but smaller than the average hornet. I have heard mixed things about the Spectricide, but Raid has always worked for us. I've done some thinking, and I might have to agree with Claude; it might not be worth it.
Claude, I collect these things. I've refurbished old dishes before, worn and torn from the environment and paint faded. But in the end, the LNBs usually still work. In my opinion, this particular situation is a rarity. I mean, where else could I find an original DISH 300 like that? Certainly not online. When the lady came to me about this, I realized it was a 300 dish and that's why I'm stuck on it. You just don't see those anymore. Evidently it was an appliance store at some point which explains the dish. That's really the only reason I'm pursuing this. If it were a DirecTV Slimline or any other dish I'd say screw it. ;-)
Also, not to brag, but I'm proud of that top photo -- makes a great desktop wallpaper ;-)
