Rats pose a significant threat to gardens, particularly during the spring breeding season. As gardeners begin to tidy their outdoor spaces, they may unknowingly attract these nocturnal pests, which seek food and shelter in gardens. Signs of rat activity include greasy tracks, gnawed wood, burrows, and shredded materials. To deter rats, experts suggest making simple changes, such as frequently rearranging items in the garden. This disrupts their territory, as rats are 'neo-phobic' and dislike new environments. Additionally, maintaining a clean garden is crucial, as clutter can attract rats. Garden expert Alan Titchmarsh emphasizes that compost heaps are particularly appealing to rats due to the warmth from decomposing materials. To make compost heaps less inviting, he recommends sealing any gaps and avoiding the addition of processed foods, which can lure rats. Instead, gardeners should use moldy fruits and green clippings to maintain a rat-free environment.
