How do you keep birds from nesting and pooping on the deck?

Answer 1

Keeping birds away from docks, decks, boats, and other structures can be a real challenge, but not impossible. If you plan at the beginning of the boating season to keep pest birds away, you will be able to enjoy your boat and deck.
Most bird control methods will require timing, persistence, variety, and a little effort on your part. First, most birds are foragers. If there is any type of food source, they are going to hang around and feast. Be sure to clean, stow, and secure any food items away from the birds. Second, be sure to remove any nests and continue to do so. Once birds begin nesting, it is almost impossible to dislodge them. Third, and most importantly, any effective bird deterrent must avoid "habituation," i.e.,

when birds no longer react to sights or sounds that were originally frightening.
A visual and auditory bird repeller

with frightening effects that change and are unpredictable is a great choice to deter nuisance birds. The WhirlyBird

Repeller

is a visual and auditory repeller.

A steady wind will cause the WhirlyBird

Repeller

to produce unsettling sounds and changing light patterns. When installed 6-8 feet above where the birds are roosting or perching, the WhirlyBird

Repeller

will continue to prevent habituation and keep birds away from your deck, dock, or boat.
There are many different bird deterrents on the market. Please be sure to talk to a representative from the company to learn if their product will work to protect your deck from nuisance birds.
