Hornets are doing me a favor

[ragkar]

I've got a bit of a problem with bats at my house. I have no attic but apparently there is an area below the shingles that is home to them. The trouble is, their main entrance is right above my front door nineteen feet above the deck. So every morning when they return, they sprinkle turds on the deck in front of the door. If that isn't swept, I track them into the house on my shoes.
About two weeks ago I noticed that I no longer had a turd carpet outside the front door. Then I noticed a small hornet nest in the rafters near the bat entrance. Apparently these mosquito eaters are afraid of hornets.
