Combining sonic repellents with castor oil granules works better than either method alone. The smell drives them away while sound keeps them from returning.
Moles dig deeper in winter to escape cold. Angle your sonic spikes downward to penetrate frozen soil more effectively.
Has anyone tested solar-powered spikes in winter? I wonder if they hold a charge with shorter daylight in northern areas.
@MoleFreeZone Lithium batteries are a game-changer! I also wrap devices in waterproof tape to prevent moisture damage.
Remember, moles just seek warmth in winter. I use repellents temporarily, then relocate them humanely in spring.
After five winters, I’ve found December installations work best, it stops moles before they dig deep tunnels.
Frozen soil conducts sound better than dry ground! Packing snow around the base improves transmission.
