We stuck rat poison in the holes then closed them up with expanding foam. No more voles.
I have been putting poison out for the last few days and also thought of the expanding foam but figgered they would just dig a new hole.
I'll give it a try this week.
Another thing I'm going to try is a couple of fake owls, one in front and another out back.
These little bastards are really pissing me off, we just did the sod this past July and it looks like crap now that the snow has gone.

p.s. that gun is cool but I'm almost positve Okotoks has a bylaw that prevents use within town limits. And, I really want to see the full minute at a million rounds per.
