There are vibrating devices that chase them away. Here is a weird way to deter them.

Here is a link that might be useful: voles

Oh I feel your pain. I hate them!! I had them strike my roses and my hosta but as far as I know not any lilies. Go to the hosta forum and you can see several post about voles. I am curious to see what others might suggest. Good luck. Judy

They have moved into my yard BIG time. They killed my Final Touch. I have put out poison. I will put out more. The best thing that has happened, a dog has come in and dug up many of their tunnels. The dog has not been into my daylily beds, but if it kills the voles, I would still be ahead.

I'm not overrun with voles, but I do have problems wih them in the garden and in my greenhouse where they choose a potted daylily, dig all the dirt out of it and eat all the roots. What I've done is place rat poision down in the holes and cover the holes with something so an animal doesn't get into it. A few days later, the pellets of poision are gone and I assume they took it to their nest. I know this works because when I've used this in the greenhouse, I've found dead voles a few days later.

fr8plkants,
I am trying the poison, but still find an occasional new area they are into. I really need to get them killed off before winter since they could make better headways if I am not outside all the time.

What is the name of the poison you use?

I am lucky in that I don't have them here in my garden. Pesky critters.

Got Voles. They live in a luxury Vole Condo in my garden. 5 years ago our 60 ft. ancient Sliver maple split in half vertically in an ice storm. The ground was rent 4 ft deep exposing the roots and forming a mini crevasse. The tree service could not get heavy equipment back there to remove the stump halves so I filled the opening with good garden soil forming a hill 5 ft tall. There is a lace leaf Japanese Maple on top and a cascade of sedums down the face. Last summer they moved in. I can't bring myself to use poison. We get cats, rabbits, squirrels and our dog in the garden. There were 7 entry holes down the face of the hill. I say "were" because there was a faux tsunami.When the sump pump was put in our pool to lower the water for winter closing the other end of the hose was put down the vole holes on the hill. After the tsunami there was a rock slide. I put pea gravel down all the holes. The gravel was assisted with a ram rod. Besides the satisfaction of the eviction the gravel will hopefully keep the tunnels from collapsing and eroding the hill. They most likely went out a back door and will be back when things dry out,but it felt good to do something.

Tarheel,
I have been using decon, and it works to an extent. Whenever they start heading around one of my iris, or daylilies, I am digging down toward the roots and sprinkling poison all around them. I have used the product that is supposed to be the same as fox and bobcat urine, and it is too soon to tell if it does anything (I doubt it, but will try whatever it takes). and I have seen some bait stations called vole Control which will be my next effort.

I take delight in stomping on any runs they make. Everyday I look for these new runs. They love my nice soft improved areas, but that is where it is dangerous, and they will find that out. It may take a while, but I am relentless in my pursuit of them. These monsters start reproducing at something like five days. Wren-garden...they are coming for you. They multiply on almost an exponential basis.

Today I ordered vole control bait stations. These little buggers are increasing every day and the urine was washed away by rain...of course. Firstt rain in two months, so it was welcome, but still. Rita, this is the first time I have had these stinkers.

When I find a plant they have targeted, I dig around the roots and add poison...that plant will cost them!

Hey Kay, Thats more or less what I have decided to do too. This is my first year with these horrible creatures and its very upsetting. I bought some poison mentioned in one of the posts on the hosta forum and hope to get some put out in some holes around the plants they have dug up in the next day or two. You know its always something it seems. Good luck, Judy

tarheel336: I feel your pain! Those varmints have been invading my daylily bed & peony beds the past 3 years--I didn't even know anything could eat peony roots. I've been fighting a holding action with them using smokers and poison, but because I live in a rural area, as soon as I manage to kill off some of them, their relatives move in. I've resigned myself to a long-term battle that requires me to be very vigilant in observing which daylily clumps collapse overnight and pull out with an easy tug--the voles eat right through the middle of the clumps.

I do have some hope though: 2 LARGE black snakes appear to have moved into my yard and I wish them happy hunting. Just wondering how I can attract more snakes!

Something has slowed down the activity, whether it's the poison I've put at the plant roots, putting poison in the run area, "stomping down" the run area, or just all of the rain we've had.

The bait stations are here and will go out tomorrow. I will put poison around every plant I have if necessary (six hundred!!!) I also intend to use the pitchfork on any new runs.

I don't live in a rural area, precisely, but I expect to have to deal with these little monsters from now on.

I thought I would give you an update. I have had no new tunnels or evidence of voles. I haven't put out the bait, but have it in ready when I need it again. I suspect that the poison I put around the roots of the plants the voles were attacking was the reason they have left. (died)

Also, I think I told you, I delighted in stomping down every tunnel they built. Whatever worked, I'm glad. I will keep a close eye on everything this winter since I expect them to return.
