It looks like I am going to have to alter my plans for what plants to put around the church and rectory. There is a flea infestation that we are dealing with due to squirrels living in one of the walls of the rectory. I have heard of lavender and mint (pennyroyal was recommended) being plants to repel fleas. What are your thoughts and are there any tips on placement of these plants and the plant behaviors and needs? I will, of course, do my own research, but I would also like any advice anyone can give. Thank you in advance. Please keep in mind that we have deer that are feasting on any tasty plant we have. Thank you again.
