Bathroom Reno Day 3.40 - Ew!

Oh, #$%&@! I got around my faucet problem by getting around it - just pulling out the tile around it. I was just pulling out the last off the drywall on the ceiling and guess what I found...a huge-ass hornet's nest in the ceiling. Ew, ew, ew, ew, ew. Yuck! I am now cowering like a child in the next room. Do I call an exterminator? I don't know (and I don't want to know) if it's still active. Once the dead hornet carcasses started to fall I headed for the hills. Ew. Yuck. Nasty. I generally don't have a problem with insects (except cockroaches) as long as they're not living in my house.
