I have that same kit. I used it last year without much luck, but I'll try it again this year. I put the queen in checked it the next day and the queen was gone. no eggs no queen, no queen at all in the hive,, ouch..
This year I will put it in the hive for a couple of days first for them to clean and get any smells out. The rack I have to hold the cups, the mice loved it and chewed all the cell cup holders off, so be careful..
It might not hurt to put a little royal jelly in the bottom of the cups first..
I'm not tense, Just terribly, terribly alert!
