I had a severe outbreak of voles several years ago. They ate probably a quarter of my cantaloupe crop and I had a 150' double row of beets that when I went to pull , the voles had been in between the two rows and eaten the majority of them. The worst part came towards the end of the season the voles had chewed so many holes in my drip tape that I had to abandon several rows. If you look at there life cycle its amazing how many can be produced in a season, the young are reproducing 30 days after birth. Anymore I am proactive, if I see signs of them I put out the wax bars of rat poison I think its called Radamix. I generally don't like poison things but I make an exception for voles.
Good luck, Marcus
