The words, pests, and birds aren’t synonymous though if the birds are being a nuisance and causing damage to your cars, roofs, and property, then it’s time for them to go. Birds can be annoying; not only are they loud, but they can also block pipes leading to your stoves, dryers, and fan vents with their nests, as well as clog your gutters and the drainage system. Then there are those acidic bird droppings and can harm the paint on our home exterior and of your car.
