Damn Moles

This is what the moles have done to my front yard. I mean, come-on. I'm used to the tunnels, but a huge mound of dirt? Little f'ers!
And let's not forget the two huge mounds in my backyard! Man, it's all because of the freaking new development behind my house. Why the hell do I have the problem and not my neighbors!?
So I bought three. One for the front (shown) and 2 for the back. These better work or I'm pulling a Bill Murray from Caddyshack.
Seriously, it's not that I'm trying to be "safe" or I don't want them to die, I've been told this is THE way to get rid of them. We'll see. They cost $30 a pop!
