Controlling Voles in Your Lawn
They are a bit harder to eliminate as the castor oil that bothers moles doesn't seem to affect them.
You might try a sonic torpedo. This is a tubular battery-operated apparatus that vibrates away and when inserted into the ground, sets up a vibration that apparently they do not like. There are also sonic devices that are advertised as being effective against these creatures. Plug them in and rodents will leave when the appropriate frequency is created.
Cats work really well. More than one cat owner has written with tales of how much dear kitty loves to bring home “presents”.
These pests hide in long grass (cut it) and piles of old boards (remove them) and other piles of vegetation (shred them and compost them) and any other place that a mouse would hide. If you remove as many of these hiding places as possible, you'll reduce the level of damage in the lawn. But unfortunately, if you live next to a hay-field or park, you'll always have them.
Physical traps work as does bait. But you have to ensure pets and children don't get into either.
Mothballs do not work (the critter simply doesn't get moths) and chewing gum also doesn't work (except that vole-dentists get more work repairing the cavities from all that gum sugar).
Mole or Vole?
If you have trouble remembering which is which – moles and voles...
M = meat eater and these are Moles. They tunnel and leave volcanoes on your lawn.
V= vegetation eater and these are Voles. They are like mice, hiding anywhere they can above ground and leave trails in the lawn after snow has melted. But not tunnels
