This question is related to my earlier question about when it is safe, from the young chipmunks' point of view, to relocate a burrow of chipmunks.
To recap the background of the earlier question:
One of my neighbors is terribly concerned that her resident chipmunks will harm her flower beds. They dig holes, and she finds the holes unsightly. She wants to trap them and relocate them.
Beyond the unsightly holes, she is concerned that the chipmunks will harm her flowers. I don't know what she is planting, because this comes from a neighborhood on-line site, and I don't know her personally.
We live in northern Virginia, 20 miles or so to the northwest of DC. According to the Virginia Department of Game and Inland Fisheries the chipmunks in question are probably the common eastern chipmunks (Tamias striatus striatus). (I say probably, because animals are migrating.)
As I say, I don't know what style of garden she favors, formal or centered on naturally occurring species, nor whether she is at all inclined to change her plantings, so I will try to be more specific:
What are non-lethal, and non-harmful (to the chipmunks) tactics to encourage the chipmunks to move away from her front yard? For example, are there candidates for a chipmunk very-friendly garden that she could plant out of sight? Almost everyone here has at least an acre.
I'd like to suggest an alternative or three to the options she is considering: amateur and perhaps premature trapping, exterminators, stuffing mothballs into the burrow, and (don't know how serious this is) getting a cat to control the chipmunks.
