Gardeners can keep rats away from bird feeders by using natural items such as garlic powder or peppermint oil, which emit strong smells that rodents dislike.
Why bird feeders attract rats
Bird feeders are a popular way to support birds when natural food supplies dwindle in winter, but they can also attract rats. Birdseed often scatters to the ground as birds feed, and rats have a sharp sense of smell, making feeders a readily available food source.
Danielle from Really Wild Bird Food explained: "Studies have shown that rats don't like strong smells such as garlic powder or peppermint oil so if you have vulnerable areas in your garden it may be worth sprinkling some around to deter rats from visiting your property."
How strong scents deter rodents
Rats rely heavily on their sensitive noses to locate food and detect danger, so they tend to be wary around potent scents. Both garlic and peppermint can irritate a rat's nose, causing enough discomfort to encourage them to leave, while also concealing the scent of seeds.
Unfamiliar odours can also make rats suspect danger is nearby, as they are less able to detect predators, making them more likely to relocate to a safer area. Unlike rats, birds do not have the same acute sense of smell, relying more on sight and sound, so they will continue to feed without significant problems.
Practical tips for applying deterrents
Spray peppermint oil or sprinkle garlic powder around the garden near the feeder, ideally in the early evening when rats are most active after dark. Place these items near potential entry points such as fences or sheds, but avoid putting them directly on the feeder or letting them contact seeds, as this could harm birds.
Topping up feeders in the morning can also help, as birds feed earlier in the day and less food remains overnight. Keeping the garden tidy, including lawns, bins and sheds, reduces hiding spots and should help drive rats away for the rest of winter.
