Rats are unwelcome visitors in gardens, particularly in winter when they seek food and shelter. Experts warn that rodents breed rapidly and carry diseases, but advise against using poison without professional guidance due to risks to wildlife and pets.
James Neal, a gardening expert from Neal Landscapes, recommends natural deterrents instead of pesticides. He suggests planting species like the Mole Plant (caper spurge), which produces strong-smelling chemicals that overwhelm rats' sensitive noses and irritate their skin on contact.
Other effective plants include sage, whose potent aroma and bitter taste repel rats. Neal notes that sage grows in any soil type with sufficient sun, making it an affordable barrier. Oregano, with its strong scent and spicy flavour, also deters rodents and protects soil from diseases.
Herbs such as peppermint, lavender, and rosemary are similarly useful due to their intense fragrances. Neal advises placing these plants around vulnerable crops, particularly in sunny spots with regular moisture, to create a natural defence against rat infestations.
