With summer underway, gardeners are seeking ways to keep rats out without harming wildlife. One affordable kitchen item—onions—can naturally deter these pests, according to experts.
Why Onions Work as a Rat Deterrent
Onions contain sulphur compounds that irritate a rat's eyes and nose, making them an effective natural repellent. Better Homes and Gardens states: "Unlike most humans, rats detest the smell of onions and garlic. Placing a few slices of fresh onion or crushed garlic in corners where rats could enter will deter them." However, experts caution that this method is not ideal for households with pets, as garlic and onion are toxic to animals. Additionally, the produce must be replaced often to prevent spoilage, which can be time-consuming and wasteful.
Safe Usage Tips
While it is unlikely a rat would consume a large amount, large quantities can be toxic if digested. Therefore, experts recommend using small slices around the garden. Other natural repellents include garlic, vinegar, and certain plants like lavender and mint, which rats tend to dislike. Keeping grass trimmed short can also reduce potential hiding spots for rats.
Additional Natural Deterrents
Planting lavender or mint around the garden can act as a natural barrier. Placing small quantities of these in areas where rats may enter can help. By following these simple tips, gardeners can keep their outdoor spaces in great shape without causing harm to wildlife.
