I am being over run by voles. They have been a problem for years now, and I am almost ready to quit gardening altogether. They have eaten shrubs, about 500$ worth of unique and gorgeous hosta, and many other plants too numerous to name. My yard had burrows everywhere. I have tried every home remedy I have heard of, to no avail. I can't use anything poisonous because I have pets, and the cats hunt the voles, though they haven't put a dent in the population. Can anyone help!
The University of California extension service has a thorough discussion on various control options for voles at this link.
