So, if you give me cookies, I would move in too!
No cookies for mouses in my garden, yet I have a new resident. There is a feeder and bird bath very accessible with lots of ground cover for little visitors to hide and gather all the seeds wanted for a happy family of critters.
A darling little field mouse has been tunneling all through my flower garden... I do hope town mouse decides to not to make a long visit to his country cousin for too long.
So I did some research and found several references to non chemical remedies. I decided to give it a try - Bounce dryer sheets. I think I scattered and tucked about 50 of those behind shrubs and under all the hostas. (I do have a large flower garden-flowers make me smile!) I'll let you know if it worked.
