“I purchased this product last year. I have a 3 car garage that the birds had pretty much taken over. I couldn't park my car in it because they would "crap" all over it. The 1 side of the garage was the worst. The entire wall and door were just covered. I put up the product and within a week they were gone and didn't return. I decided to get ahead of the problem earlier this year. I'll be happy to update you later in the summer. Thanks.”
