Today I placed sections of pool noodles in the openings, and stuffed the center holes with moth balls...we will see if that works?!
I do like the idea of the rubber snakes though...but with so many rattlers in this area maybe the birds will ignore them.
As for the fake owl...I use one here at home for my garden area, but actually the local red tailed hawks do a much better job of controlling the bird population...I wonder if could get the hawks to move across town to my storage yard??
Thanks again for the ideas.
