I 2nd Mac on Bird B Gone. Take a full rainy day & 2/3 tubes of that stuff & put it EVERYWHERE they land. They will be gone in 48 hrs & stay gone. Will cost ya about $40 & problem is gone!I used to use a product called Bird B gone. Came in a tube that fit in a caulking gun. It was basically a substance you applied and it stayed effective for maybe 6 months. It was just real sticky stuff that the birds hated. BB guns are also effective if you're a good shot.
And I'll take a Crown & CokeGreat. You can buy me a beer when you see me.
