Mole mound in the lawnIt did not take long for the mole calls to start coming into our office this year. We had a few weeks of vole damage identification calls and now have moved on to calls relating to mole damage identification and control.  

Adult moles are between 5.5”-7.5” in length and may weigh between 2 and 3.5 ounces. They are very active and seek food day and night all year long. Earthworms and larval insects are their preferred food source and moles can consume up to half of their weight each day.

Moles breed in late winter and early spring producing an average of four young in April or May. At approximately four weeks of age the young moles leave the nest and are on their own.

Mole mounds and tunnel damage
Problems associated with moles are surface tunnels and mounds or molehills found in lawns, golf courses and cemeteries. The upheaved ridges of mole tunnels are unsightly and can make lawn mowing difficult. When tunnels are located close to the surface the roots of nearby plants can be negatively impacted and the plants can turn color or in some instances die.

How to get rid of moles
The surest way to control mole damage is to remove them from the area by trapping.

The three most common mole traps include

  1. scissor-jawed,
  2. harpoon, and
  3. choker loop.

All are placed within an existing tunnel and are set off as the mole passes through.

For more detailed information on these traps please see the publication Controlling Nuisance Moles. One of the secrets for successfully trapping moles is to find an active tunnel. There is a very short video showing how to find an active tunnel at the link listed here
