Does not work for these voles, anyways. They ate everything EXCEPT the Daffodils! They have to be killed...only way. I know alot of people hate that, but otherwise you can kiss your garden goodbye around here. They eat the roots of big trees and they topple over. They eat all the roots to rosebushes, not to mention every bulb (cept Daffs)....
