Gardening expert Ash Read from Indoor Plants has shared advice on keeping gardens rat-free, noting that these rodents can turn a tranquil outdoor space into a nightmare. He reassured troubled gardeners, explaining that while humans may enjoy the scent of lavender or rosemary, rats are far less appreciative.
According to Read, rosemary's presence in the garden can make rats think twice before settling, while marigolds, with their unique smell, act as a rodent repellent. Peppermint is another effective deterrent, with Read noting that its robust aroma sends rats sprinting in the opposite direction.
For a homemade peppermint spray, Read suggests combining a few drops of essential oil with water and regularly applying the solution around entry points and cherished plants. He also recommends expanding the toolkit with other essential oils such as lemon, citronella, and eucalyptus. Chrysanthemums can also discourage rats, but Read's favourite is lavender, describing it as a love-hate relationship: humans love it, rats hate it.
Carlos Garcia, whose parents founded Total Clean, added that plants such as mint, lavender, rosemary, marigold, daffodils, fennel, garlic, and onions are less attractive to rats due to their scent and taste. He also urged gardeners to regularly monitor the garden for signs of rat activity and address issues promptly to prevent an infestation. Placing garlic cloves near entry points works well, but they should be swapped out regularly, particularly after rainfall.
Read stressed the importance of tidiness, stating that rats thrive in messy, overgrown places. Maintaining a neat garden with short grass, minimal overgrowth, and organised tools helps reduce hiding spots. He also advised moving items around to break the rats' routine and blocking access to decking and garden structures.
