Gardeners are being encouraged to place garlic bulbs in their gardens this winter as a natural deterrent against rats and slugs. Experts suggest that the strong aroma of garlic can effectively repel these common pests without the need for chemicals.
According to specialists at Proof Pest Control, garlic's powerful smell disrupts rats' reliance on their sense of smell for finding food and sensing threats. Crushed garlic cloves can be scattered in areas where rat activity is noticed, or placed in mesh pouches for a longer-lasting effect. A garlic spray, made by blending garlic oil with water, can also be applied near potential nesting sites to create an unwelcoming barrier.
Garlic is also useful for deterring slugs, which are repelled by the compound allicin released when garlic is crushed. Though slugs may initially be attracted to the scent, it eventually irritates their mucous membranes, causing them to retreat. A homemade garlic water spray can be applied to plants weekly throughout the year to protect them from slug damage.
