We are having such a time getting rid of moles. We have tried mole pesticide in the holes and scattered all over our yard. We've tried the soundwave posts that you put in the ground to deter the moles. We have an outdoor cat and he may kill one a month so not a lot of interest there. What else can we do? These moles are leaving dirt piles all over our yard. We have an acre that they are just 'eating' right up!!! Please help.
