Had a similar episode a month or so back, only difference was it was a family of them, and they took up residance under our deck. Like Tom, I found that GT 3555's with Snuffers, shot from the second floor window blind / stand are pretty good medicine for these pests.
My shooting wasn't quite as good, I'm mainly a ground pounder not used to elevated shots, and it showed; first couple shots were harmlessly high.
I eventually got it figured out and shot the youngin shown here, and I got mama as well. Mama made a bloody mess, a mighty doggone good thing that the Mrs. was at work and I had time to get the hose out...
