I need help please. I have a very large planted area covered in pine needles as mulch. Every morning there is distruction everywhere. The pine needles are tunneled and the dirt is kicked back as in digging. I have tried fencing, a very expensive repellent, I have a dog and a cat, and nothing seems to help.

There are rabbits, possums and gosh knows what else is out there. I am ready to try blood meal, does it work??? Any other suggestions, I am getting desperate and may have to bring out the cure of a 22!!
