I think I founf a solution for squirrel problem
A friend of mine got a work contract in United Arab emirate and he left the country to stay there for 8 years. He has a little dig called Jack Russel terrier and did not know what to do with him. I offered to adopt the little fellow. He goes with me to check on my trees and I discovered how much he hates squirrels. He makes a lot of noise parking and chases them and they are very scared of him. He chased one and the squirrel jumped high on the tree. The dog waited for him to come down parking and angry. I stood calm and noticed the action. The squirrel did not eat any fruit, he just was looking to scape, then jumped and ran away. Lately I don't see much squirrels in my backyard any more I have a little guard. I am thinking to get another little Guard.
