My pollen feeder is a hive body that sits on the stand right next to my other hives. Syrup feeders need to be located a distance away to prevent robbing.
I doubt giving them dry sub will get them off the coffee grounds, different needs.

Well that is good news about the feeder location.
What in the world is in coffee grounds that a bee would need?

 

[JWPalmer]

Coffee is loaded with various alkaloid compounds. Perhaps there is something that is needed in their diet in the coffee. I believe the true nature of bee nutrition is poorly understood. Anytime I see bees foraging on weird stuff I figure they know better than I do. Or maybe the caffeine gives them a little buzzzzzzz?

It's been several years, but there was a study that showed caffeine does give bees a "buz."
