Peak breeding season for rats is now underway, with these rodents becoming increasingly prevalent during the summer months across the UK, where conditions are ideal for them to find food and shelter. Kitchens, gardens, garages, barns, rooftops, and cellars are among the areas these disease-carrying vermin frequently invade, often causing significant damage.
Although rats are unwelcome in any home or garden, several effective methods can deter them naturally without resorting to harmful measures such as kill traps or poison baits. Rats have poor eyesight but an exceptionally keen sense of smell, which can be exploited to drive them away. While professional pest control is recommended for severe infestations, certain scents greatly irritate a rat's respiratory system, discouraging them from entering your home, according to the Express.
Three Herbs That Repel Rats
Three herbs prove useful in the fight against rats, and deploying them in straightforward ways helps keep these pests away from your property.
Basil
Using basil oil as a spray or in a diffuser is a clever solution to humanely eliminate rats, as the fragrance is highly disagreeable to them. Placing basil plants near doorways, access points, and areas where rats are suspected also helps discourage these rodents.
Lemongrass
Lemongrass is frequently mentioned as an outstanding natural rat repellent. To use it, infuse lemongrass—either shop-bought or from your garden—in boiling water to create a tea, then decant it into a spray bottle and apply throughout your property. Alternatively, use concentrated lemongrass or citronella essential oils in a diffuser to distribute the aroma. Note that lighting a lemongrass or citronella candle in one small corner is not sufficient to fully repel rats.
Thyme
Various cultivated types of thyme can be employed against rats. These varieties produce sharp, powerful aromas that instantly repel rats when placed in appropriate locations. Thyme oil in a scent diffuser or as a diluted spray are frequently suggested techniques. Planting common thyme (Thymus vulgaris) or golden lemon thyme (Thymus x citriodorus 'Aureus') in your garden is also a deterrent, as both are known to drive rats away. Rats are equally repelled by the aromas of peppermint and citrus, as well as cayenne pepper and chili flakes.
