Reader question: How can I effectively get rid of mole rats?
Combining multiple proven methods yields the best results for controlling voles and mole rats. Encourage natural predators like weasels, foxes, and birds of prey. These pests avoid cultivated soil that disrupts their tunnels. They also dislike lawns and grassy meadows, especially those with cocksfoot grass. Elderberry's strong scent repels them—plant an elderberry hedge as a protective barrier around vulnerable areas. Alternatively, pour elderberry manure, castor oil cake, or cedar shavings directly into their tunnels. These rodents are also highly sensitive to noise vibrations.
