We have had issues with woodpeckers hammering our metal chimney right above our bedroom in the spring at dawn for years. Pounding on the wall, throwing stuff near them, yelling - nothing worked for long. Called Bird Control last year. They came out quickly, put down some bird repellant, and our woodpecker problem disappeared. I now have a reminder early every spring to call Bird Control!
These guys came right out and humanely took care of our bird problem. We had some sparrows living in an eave of our roof and making tons of noise. Not only did they have a permanent, practically invisible solution, they were very reasonable on cost and came in $100 less than other pest control companies.
