Many stores also sell bird repellent. Just make sure it is safe to use if you have house pets.
You also can purchase fake cats and owls, which are predators of birds. Hang them around the front of your house to scare the birds from your wreath.
During the holidays, people like to decorate their homes, and the outside is just as fun to decorate as the inside. Wreaths can be made to celebrate many different holidays, but once you hang a wreath on your front door, it becomes an enticing place for birds to build a nest. You may think this is cute at first, however, you may change your mind when the birds start leaving their droppings on your front door.
Find any aluminum products that you may have in your house and hang them up near your wreath. Birds do not like shiny objects, and this will deter them from coming anywhere near your wreath.
Fill a bowl with warm water. Crush up some chili peppers, and add them to the bowl. Set the bowl out in the sun for two days.
Pour the contents of the bowl in an empty spray bottle. Spray this mixture on your wreath. It will not hurt the wreath, but it will repel the birds if they get past the aluminum.
