I think I may have a mole(s). This has been going on for about 3 years or so. At spring time (right now) I have been noticing that something is digging under my little back door concrete stoop. Damage has already started on the stoop and im worried that more will occur. How do I determine what my nuisance is?

Good morning, Do you notice tunnels of slightly upturned soil in your yard? Or is the digging confined just to the area under the stoop? If you will take a picture of the damage with a ruler next to the digging (for scale) and send me the photo I can help you determine whether it is a mole or another species that is causing the damage. We can then pick the best method to abate the damage.
