Styrofoam Mini Mating Nucs allow you to breed your own queens. The larger size allows breeders to "pre-grow" frames and helps keep the bees from plugging out the frames. The high density construction provides optimal temperature stability.

This nuc comes with two built-in feeders, two closable entrances, 2 removeable bottom panels for ventilation and easy clean out, slots for 6 easy-access frames (sold separately here), and two built-in excluders to keep the queen out of the feeder. This nuc comes completely assembled. 

Measures 8-1/2" x 17-3/4" x 11"
