I don't have moles or gophers but several years ago saw definite signs of voles round my apple tree when the snow came off. I probably have a rat but I haven't been able to catch sight of it but I hear the rustling in the myrtle and see the movement of the leaves by something bigger than an mouse. As I get rid of most of the myrtle, still about a third of the back yard to go, I hope to get rid of him/her, There are a couple of neighbor cats who visit my yard so don't want to put out any poison.
