How to Tell an Active Mole Run From an Abandoned One
Most of the ridges in a mole-damaged lawn are dead ground the animal will never use again. Knowing which are live is the difference between trapping and waiting.
Why so many tunnels go quiet
A mole pushing a surface run is searching. If a stretch of soil does not hold enough worms, it moves on and that tunnel is finished — it stays visible in your lawn for weeks while the animal never returns to it.
Runs that connect good feeding ground to the nest are different. Those get travelled repeatedly, sometimes several times a day, and those are the only runs worth setting on.
The test
Press a short section of the ridge flat with your foot. Mark it — a golf tee or a stick beside it works. Check it in twenty-four hours.
If the run is live it will be pushed back up, often within hours. If it is still flat after a day or two, that run is abandoned and nothing you put in it will ever be visited.
What it tells you about the yard
Doing this across half a dozen ridges gives you a map. The pattern of which ones reopen usually reveals the travel corridor — very often along a fence line, a driveway edge, a bed border, or the shaded strip beside a foundation.
It also tends to reveal how few animals are involved. Homeowners looking at a heavily ridged lawn routinely assume a dozen moles. Eastern moles are largely solitary and territorial, and a single animal can produce a startling amount of damage.
If you are doing this before calling us
Good — it genuinely helps. Flag the runs that come back up and leave them undisturbed. Arriving to a yard where the live runs are already marked means we can set into known travel routes on the first visit.
It costs you nothing and it makes the job faster.
