To deter squirrels from eating pecans, try using physical barriers like metal flashing around the tree trunk or netting over branches. You can also use scent deterrents like hot pepper spray or mothballs, or create a distraction with a bird bath or deer antlers placed near the tree. [1, 2, 3, 4, 5]
Here's a more detailed breakdown of methods:
Physical Barriers:
• Metal flashing: Wrap a wide (2-foot) band of sheet metal around the tree trunk to prevent squirrels from climbing up. Ensure it's securely fastened and extends far enough to deter jumping from nearby branches. [1, 6, 7]
• Netting: Cover branches with netting to prevent squirrels from reaching the pecans. Consider using a mesh material that allows air circulation and sunlight. [8, 9, 10]
Scent Deterrents:
• Hot pepper spray: Create a spray with capsaicin (the active ingredient in hot peppers) and apply it to the tree trunk, branches, and the ground around the tree. [4, 11]
• Mothballs: Place mothballs in mesh bags and hang them in the tree. Be mindful of the strong odor and potential harm to other wildlife. [2, 4]
• Other scents: Some gardeners report success with coffee grounds, peppermint oil, or predator urine sprays. [3, 12]
Other Methods:
• Distraction: Provide a bird bath or a designated area with food to divert squirrels from your pecan tree. [5]
• Deer Antlers: Attaching deer antlers to the tree can provide a gnawing alternative for squirrels. [5]
• Trapping: If the problem is severe, humane trapping and relocation of squirrels can be an option, but be aware that new squirrels may move in. [1, 13]
• Cleanliness: Keep the area around the tree clear of fallen pecans and other debris to reduce the attractiveness of the area for squirrels. [14]
