Exclusion is one of the best choices for homeowners. Evict starlings wherever they have gained entrance to your home or buildings and seal the entrance with hardware cloth or metal flashing. Light materials such as nylon or plastic netting and window screen will not keep out determined starlings as they can easily tear these materials out. Keep birdhouse openings to less than 1½″ in diameter to exclude starlings. “Porcupine” wire, which has several parallel rows of 3″ stiff wire attached, is also useful in deterring birds from roosting or nesting areas. Use netting to cover fruit trees and bushes.
