My yard is becoming overrun. I'm mowing the lawn, take a step, and squish I sink a few inches or more into a hole. At least once I sunk deep enough to reveal a junction of several tunnels, all burrowing pretty deeply.
First question is whether this is chipmunks or moles. The holes in the front hard are big enough that I would fit maybe 3-4 fingers down one if I tried. When I fill them they are always dug out the next day. Just last night I saw a pair of eyes and a nose looking back at me but couldn't tell what it was.
In the back yard, though, there are much smaller holes, like maybe 1 finger sized. These don't seem to be nearly the same problem. The front yard is beginning to look like a minefield.
What are my options? I figure that I can leave it and just keep filling them, which is not only annoying but also dangerous since I'm never sure how deeply I'm going to sink. A second option is a some sort of repellant to make them take a hike...but probably into my neighbors' yards. Third I could smoke em to death, but I'd really rather not do that.
Options? Is there a way to get them to stop digging in my yard in such a way that they don't just come back again next week? Without killing them, preferably?
