That night I couldn't sleep.
I kept searching. "Why does mole removal never work." "Permanent mole solution."
Then I found a university extension article.
One paragraph explained everything:
"When a mole is removed, the territory becomes vacant. Neighboring moles detect the vacancy and move in within 2–4 weeks. This is why removal-based control requires continuous effort."
Requires. Not "might require." REQUIRES.
The system is structurally designed to never end.
Here's what Rick didn't explain:
Moles are almost completely blind. They navigate entirely through vibration.
The seismic pulses of earthworms. The sound of grubs. The signals from other moles digging.
That's how they map territory. Find food. Choose where to live.
When you trap a mole, the vibrations don't change.
The territory still looks safe, full of food, perfectly desirable to the next mole.
You evicted the tenant but left the "For Rent" sign up.
Someone else always moves in.
That's not a pest control failure. That's the pest control business model.
