Things You'll Need
Instructions
Install bird spikes along awnings, gutters and similar places where doves might perch in and around the deck. Bird spikes are strips of small, pointy spikes that will discourage birds from landing.
Install a fake owl somewhere near the deck in a highly visible spot. Owls are predators of many other birds, and even a fake one will be enough to scare away many birds.
Install an electronic squawker, which is an electronic device that periodically emits distress calls or predator calls. A squawker installed in the vicinity of your deck will help scare away doves congregating in the area.
Install a bird feeder somewhere else on your property. The bird feeder will attract the doves, and the doves will congregate there instead of on your deck.
Clean the deck of any food scraps and other debris that might be on it. Food scraps will attract birds, and debris allowed to gather may make an ideal home for insects and other small animals that doves may prey upon.
