Gardeners plagued by rats may find a natural solution using three common household ingredients that rats detest, according to pest control experts. Alastair Mayne, chief operating officer at Garolla, explains that prevention is key, and making the garden less inviting can deter rodents without resorting to toxic methods.
Rats have a highly sensitive sense of smell, and strong scents like peppermint oil, vinegar, and garlic can irritate their noses and eyes, making them avoid treated areas. These scents also disrupt their ability to navigate and find food, further discouraging them from staying.
To create a homemade repellent, boil five garlic cloves in water for ten minutes, then allow the water to cool. Strain the liquid into a spray bottle, add ten drops of peppermint oil, and fill the rest with white vinegar. Spray this mixture around the garden, focusing on entry points. Alternatively, cotton balls soaked in vinegar or peppermint oil can be placed around the garden and replaced every few days after rain.
Another effective deterrent is black pepper, which can be sprinkled around cracks, crevices, and burrows to irritate rats' noses. However, maintaining a clean garden is crucial, as rats are attracted to food sources and hiding places. Mayne advises taking out rubbish regularly, cleaning spills, and wiping down surfaces to create an environment with little appeal for pests.
