@Wil my neighbor made mine (after he adopted one of my lost swarms and I helped him get them going)
That's a great idea.If I was to open feed powdered sub I would half fill 3 or so quart jars with feed.
Then lay these on their sides on a solid bottom, cover with a box and lid to "keep your powder dry".
Then Sprinkle a some powder on the entrance to help them find it.
I'll check it out. I have Fred Dunns videos bookmarked so that I can view from time to time.Fred Dunn just did a video that covers this, and he one ups the jar trick I stole from Duck River.
But I think I also read something by Miller along the same lines.
I believe he makes reference to feeder location as well.
