Hay covers can help reduce the risk of pest infestations by providing a physical barrier that limits access to the hay. While they are effective in shielding hay from environmental factors like moisture and sunlight, they are not always entirely pest-proof.
Small gaps, tears, or inadequate securing of the cover can still allow pests such as rodents, insects, or birds to reach the hay. To enhance protection, it is important to ensure the cover is properly fitted and securely fastened, and to combine it with other pest control measures such as using bait stations, traps, or physical barriers.
