18 Possible Solutions No scientific evidence but worth a try: Deodorant soap tied to tree branches Egg mixture sprayed on foliage –2 eggs –1 to 2 cups cold water –Mix in high speed blender –Add to gallon of water and spray on foliage –Does not wash off foliage easily, reapply 2-3 times per season

19 Possible Solutions Noise Alarms –Using sound not effective –More bothersome to homeowner than deer –Deer become accustomed to noise
