Mole and Vole Fallout

Asked February 7, 2020, 11:26 PM EST

I moved into a newly built house 5 years ago. I imported lots of compost and worked hard to get the lawn flat and smooth. Early the first fall the moles moved in. They have made lots of hills and tunnels. I trapped a few moles that first year and have trapped 6 or 7 each year for the past 4 years. Now my lawn is full of holes and is very uneven. What can I do to get the lawn back to being more even? Thanks, Peter

Thank you for your question. And congratulations to you for improving your yard to welcome moles and/or voles! They love ‘loose’ soil, so they can relax. But, that’s what they do, being part of the natural environment. If you really want to eliminate these valuable mammals from your yard, here are some tips: https://extension.oregonstate.edu/news/moles-voles-gophers-dig-garden and: https://www.oregon.gov/ODA/shared/Documents/Publications/PesticidesPARC/ControllingMolesOSU.pdf Good luck!

My question was how to get my lawn more even after the damage done by the moles. Any suggestions would be appreciated.

Thanks,
Peter

You'll want to acquire some quality, organic, weed-free topsoil, and shovel it into the holes. It is not recommended that you bring in a front loader, or a truck, since their weight will compact the soil. Gently tamp the new soil down into the holes. This is a good time to overseed your yard.

Hope these are helpful.

Thanks for your help.
