That’s a weird looking squirrel.
Hey @Girly, I didn’t see aluminum window screen in your list of things to try. I don’t have squirrel problems but remember reading about it here.
You might try plastic berry clamshells also if you have any laying around.
Thanks @hoosierbanana!!! I actually saw those on a youtube video and tried it last year. I used zip ties but the staples in your link looks more neat! It was a lot more work than using bags but did much better at keeping squirrels out than the bags!
Not sure how he made it in the small entrance. Only thing I’ve caught and no squirrels.
