Here are the ways we recommend you bird-proof your home in Knoxville TN: Repellent sprays: You can make a repellent spray with crushed chili peppers, vinegar, and water. Stir in together and heat in a crockpot or sunlight for an effective bird repellent spray. Bird spikes: Setting up bird spikes in areas where birds commonly roost can deter them from hanging out around your property. Garden balls: Setting up these reflective balls can scare off birds with bright lights and the semblance of predator eyes. Predators: You can buy figurines of predators like cats or owls to scare birds off. Make sure you rotate them so birds think they’re active threats.
