It's incredibly frustrating to find your beautiful wooden garden bench gnawed and damaged by squirrels. Don't worry, you're not alone, and there are several effective, humane strategies you can use to stop this behavior. First, understand *why* they chew: their teeth constantly grow, and hard wood is perfect for filing them down. To protect your bench, start with physical barriers. Wrap the most vulnerable legs and arms with metal flashing, aluminum sheets, or hardware cloth. Squirrels hate the feel and can't chew through it. For a more aesthetic option, try copper mesh.
Next, employ natural repellents. Create a homemade spray using cayenne pepper, crushed red pepper flakes, or vinegar mixed with water. Reapply after rain. Commercial capsaicin-based or predator urine (like fox) sprays are also highly effective. Make the area less appealing by removing other food sources like bird feeders and fallen nuts.
For a long-term solution, consider providing a sacrificial wood block away from your bench to divert their chewing instinct. Consistency is key. Reapply repellents regularly and inspect barriers. By combining these methods—blocking access, using strong scents/tastes, and removing attractants—you can enjoy your squirrel-free, intact wooden bench for seasons to come.
