Description
These door plugs will help prevent starlings, sparrows, and hopefully many other types of critters from taking over your purple martin house or gourds. Rest assured that the units or gourds are remaining clean and safe for your purple martins to arrive. This is a great way to keep your martin house and gourds in good condition when the purple martins have moved south for the off season and makes cleaning your purple martin house easier when the new season come around.
