While traditional pest control methods can be effective, they often involve chemicals that could harm rats, other wildlife or the environment. Luckily, a completely natural solution might be simpler and more effective than you think - growing certain plants that rats can’t stand.

According to pest control experts at Buzz Boss, there are four specific plants that “add charm” to your garden while doubling up as powerful rat repellents. These plants not only help to keep rats at bay but also offer a range of benefits, from fragrant blooms to delicious flavours when added to food. By incorporating them among your other plants, you can create a more pleasant and eco-friendly garden while keeping unwanted rodents away.

Lavender

Lavender is more than just a fragrant herb used for freshening the house. This perennial beauty is a “great rat repellent,” thanks to its strong scent that “rats dislike".

On top of that, its essential oils serve as “natural repellents for rats and other pests,” including mosquitoes and flies.

The soothing, classic aroma humans love combined with its protective qualities ensures that rats are likely to keep their distance.

Onions

Another powerhouse in the fight against rats is the humble onion.

“It’s a powerful rat repellent because of its pungent smell and taste,” said the experts.

Onions contain sulphur compounds that irritate rats’ eyes and noses, while allicin can lead to severe health issues like anemia if ingested - so it will be sure to keep them at bay.

Chrysanthemums

Chrysanthemums aren’t just lovely to look at; they’re also “effective rat repellents” due to their high pyrethrin content which affects the nervous system of rats, driving them away from your garden.

The experts recommend selecting varieties with prominent yellow centres, where the pyrethrin is most concentrated.

Their stunning blooms in late summer to autumn will not only enhance your garden’s appearance but also serve as a defence against unwanted pests.

Black pepper

A surprising rat repellent, black pepper contains piperine, which “stimulates the pain receptors of rats and other mammals, causing them to sneeze, cough, and scurry away immediately".

This spice, which grows on a tropical vine, is a must-have in any garden looking to ward off rats.

Growing it in pots, trellises, or greenhouses gives you access to a powerful repellent while also adding a bit of spice to your cooking.
