I sure could use some pollen traps this year. I have never seen anything like it. I have quite a few hives that are pollen bound in the brood nest. Today I can across a 5 frame nuc with a complete frame packed with polled. I usually struggle to find good pollen frames for cell starters, but not this year.
I just saw this thread Phillip. My main nectar flow is not that strong, but my bees cram boxes full of pollen during the summer. So ...I began collecting pollen last year using this one from betterbee. https://www.betterbee.com/pollen-collection/ptrap1-anatomic-pollen-trap.aspThis year I added 2 of these from mannlake. https://www.mannlakeltd.com/8-frame-superior-pollen-trapBoth work. Last you I got 2 quarts of pollen off the betterbee trap, with intermittent use.I've gotten about 3 quarts so far off of 1 hive with the mannlake trap. The 2nd mannlake trap has netted nothing - I think there might be something wrong with it (I've tried it on 2 hives so far). I think with beekeeping - you harvest what the bees want to (or can) bring in. In my case - it seems to be pollen, more than honey.
