Mole Activity Identification 101
Mole mounds are circular. The mounds often remind me of a volcano with stubby cigar shaped clods strewn on top. The characteristic shape and clods are created as the mole pushes the earth to the surface up through the center of the mound with its front paws. The earthen plug that is so characteristic of a gopher, is not visible in a mole mound. However, if the soil is cleared, the earthen plug sealing the tunnel will be found in the center of the cleared area. Mound size can range from 4 to 24 inches across. Deep excavation produces larger mounds. Heavy mounding in a small areas indicates nesting preparation. Counting the number of mounds, especially during spring and fall, is not a reliable method of taking a mole census. Experts believe that 2 to 5 moles per acre is a lot of moles!
Shallow surface tunnels used as travel lanes. Travel lanes are straighter than foraging tunnels and usually follow the path of least resistance; man made borders such as sidewalks, foundations, as well as mulched areas. This system of travel lanes to numerous feeding areas supply a large amount of worms, grubs, larvae, etc. once established.
