Salt sprinkled on all the paths and on door/window sashes works well, when I always grew up my mother always planted a peony plant away from the house. It was something that has been passing along down her mother's side for generations. Which reminds me I need a new one this year I moved. Plain old Dryed Bay leaves was the other custom we do as a pass down from the women in my mother side. Spring mean new leaves in kitchen cabinets, drawers etc.
If that should fail..... soak the hills in gasoline before it rains....... rain forces it in hills. Works on all types. If you want to speed up those big mound. soak half day & then bbq the little buggers!!
