Are there any bird controls that will stop birds pecking my veranda rails or roof?
Unfortunately most products marketed as bird repellents have not be proven to be very effective, and may also not be suitable for painted surfaces such as veranda rails. It also depends on the bird species that you are trying to discourage. Clear perspex sheeting has been used on city buildings to prevent pigeons from being able to grip onto surfaces and has been effective at stopping them from roosting or nesting. You may need to explore creative building solutions or ask at local hardware stores for good ideas.
