I've searched for any threads on this subject but came up empty, so if I've missed something please let me know.
I just discovered that I've got moles or voles tunneling on one of the dams, and that usually means I've got a grub problem. In the past, I've just used a grub control, and the moles/voles would then find a new home in a short period of time. But I've never had a situation where I could have runoff into a pond, and want to see what if anything is safe to use around a pond with fish.
Any suggestions? Thanks.
