Where do you see troyers with excluder? Troyers come in round or conley II. The PMCA excluder gourds come with excluder entrance. The excluder II is very starling resistant. I have Conley II entrances and no starlings but the excluder II is more starling resistant IMO.

Only option I've ever seen from Troyers is round or Conley II. Maybe someone else is changing them up somehow. I have been using Troyer Gourds with Conley II's now for many years and have only ever had one breach. It took a couple days but I got it trapped and no others have ever been able to get in.

Hi Ladybug,
My short and sweet answer is Conley 2. I've had the Conley II entrances for 15 years and have never had a starling get in.
Mite control, heat venting, predator protection and additional feeding during bad weather add up to success.
