Jeff,
Best of luck with whatever you try with getting rid of moles! They are so bad this year ours are brazen enough to visit us on the patio while we sit outside. It drives the dogs crazy! They have to cross the patio to get from one flower bed to another but they are entertaining to watch run .... blind little mess makers.
If your PA 'yard' is anything like mine it's extremely large and surrounded by deep woods and untreated properties. So treating to kill grubs is ok but a never ending battle and besides that I hate pesticides and the after effects on pets and people.
I still say, if you can't live with the moles get a cat [and I don't care for cats]. It's the only fail proof, safe method to get rid of them and those pesky 'protected' chipmonks!
