looks like i have have varmints....and lots of them, and I am P.O.'d. I live in the Suburbs in SE, Pennsylvania.
1 Possible Ground hog: OMG! see pic
2 Field mice and or Voles: confirmed
3 Rabbits: Confirmed
How do I attack and kill with extreme prejudice?
Here is what i think are Field mice or Voles..lots of critter trails leading into holes like this.
Here is what I think is a rabbit warren...I saw babies last year come out of a hole this size.
And saving the best for last, i haven't mowed the lawn in 3 weeks or more, went to the shed. I saw earlier this year my concrete pad crumbling , i thought it was Rain washing out the soil...till i found this pile of dirt.
Ground HOG????
This thing has moved 4" chunks of concrete.

I Guess living under the Shed isn't good enough anymore.
