Things that go bump in the night

Life has been crazy the last couple of weeks!  With the boys back at school, I've been able to get back in to my intense workout routine.  I'm exhausted by the end of the day!

Tonight as I was getting ready to close everything up for the night and head to bed, my dog started barking like crazy at the screen door.  Worried that we had some rouge wild animal on the prowl in my backyard, I flipped the light on and saw ... nothing.

A couple minutes later, he was barking again, this time looking intently at something on the ground just outside the screen door.  Afraid I'd see a snake or some other wildlife, I took my I'm ready for whatever this might be stance and flipped the light on.  I didn't see anything, but the motion sensor light came on immediately, so I opened the screen door and peeked out.  I didn't see anything until I peeked over to my right and there he was, the little bugger toad that has been digging causeway under passes between my neighbors house and mine!

I really don't mind frogs, they are one animal I'm ok with, but the swiss cheese he has made along the fence line one one side is pushing me to my limits.  Anyone have any ideas for how to get rid of this bugger?  He's about the size of a closed fist!
