Excluder entrance holes are widely regarded as the most restrictive of SREH and work very well to control starlings from entering your martin house, where other SREH may fail. Install plates by using either screws, bolts, or even pop rivets which are NOT included. We will send instructions. As SREH are wider that round entrances, you will have to enlarge your houses original entrance.

Protection from the destruction that can be caused by European Starlings is easy and convenient with these doors.
