Hi:
 
               Does anybody know a GOOD method of keeping yellow jackets
out of my nucs?
I have to "harvest"  300 queens , there is no nectar flow, there is some
robbing  because our season is almost over. I avoid robbing for three or
more hours  placing a common feeder (a drum with syrup). The bees go to
feed and do not disturb me when I open the nucs to pick up the queens but I
need to be sure to keep the yellow jackets a couple of hours away. I know
some beekeepers make  baits.  Any idea ?
 
 
Thanks
