Every winter teh chipmonks burrow into my greenhouse. I am an animal lover but they have decimated some exotic tulip bulbs last year and are digging in some companion plants to eat the roots. I have recently discovered nibblations on my Black Paph roots and now they must die. I put out rat bars but had hears they hate strong smell so I was going to heavily spray the floor with a clove rosemary natural insect repellant oil, Any ideas? I do not have a cat and my dog, Mr Otis, would only make friends with them.
