For those who have used it, I was wondering:
1. I have top entrances on my hives made by placing shims under the front of the inner cover. Do I need to remove them while I treat?
2. Do I really need to use the tray, or can I scoop the gel out and just spread it onto the top of the frames? (so I won't need a spacer)
3. The instructions say to place the trays on top of the brood frames. If I have two deeps of brood, should I still go to the top, or to the top of the bottom box.
Thanks. I hope these questions aren't too redundant-
