Nesting birds are a common problem among gardeners who grow flowers in hanging baskets. Birds seek out spots where they can make nests that will provide shelter from predators and inclement weather. Hanging baskets often provide the perfect spot, from a bird's perspective. Once birds build a nest, it is not a good idea to disturb the birds. For this reason, preventing the birds from nesting in the first place is the best course of action.
Wear plastic gloves and slice the jalapeno peppers and the garlic cloves so you have raw edges of each.
Rub the raw surfaces of the garlic gloves and jalapeno peppers along the rims of the hanging baskets. The oils from the garlic and peppers will deter birds from nesting in the baskets. Apply fresh garlic and pepper one time each week.
Insert one plastic pinwheel in each side of the hanging basket so the plant has a pinwheel to the left and right of it. The pinwheels will move and give off noise and light and this will frighten away birds.
Hang the wind chimes near the hanging baskets to create noise and movement. This will deter nesting in the hanging baskets.
