My wife and I live in upstate NY and for the first time last year had a
problem with some sort of underground pest. I've read that moles don't eat
roots, but these holes look just like mole tunnels. I have noticed that
there are quite a few chipmunks around, but I thought the holes would be
bigger. Will chipmunks take out a root system from underneath? What
happens is this: You notice the lilly leaves are starting to wilt -- when
you touch the plant, it just falls over. The root is completely gone, and
there's a tunnel under it.

I have been making wire baskets out of hardware cloth for this year's
plantings, but that's a LOT of work. I would much prefer to get rid of
whatever it is that is eating them. I think we might have voles and/or
shrews too, since we living in the woods. I've got an electric fence to
keep the deer away, but this is driving us crazy. Thanks for any help!
