Wyatt Mangum on Top Bar Beekeeping

Wyatt Mangum is a professor at the University of Mary Washington in Virginia. He also has written a monthly column for American Bee Journal for years and years without ever missing a month on honey bee biology. He kept bees as a boy and then started over in 1986. He keeps all of his bees in top bar hives. His book on top bar beekeeping is in the final stages. I want to buy it the minute it is available.  He spoke at EAS in Boone at the beginning of this month.



He likes top bar hives and builds them now according to his own standard although there is no industry standard. Here are a few of his hives below. The photo below shows one that he built by weaving sticks together with telephone wire to form the sloping sides of the hive!


Because he does keep to his own standard, then he can easily transfer combs from one hive to another since the slope angle is the same on every box. He uses his own template.

He starts with a 1 X 12. The dimensions for the end boards are 12" sides, 17.5" top and 9.25" bottom. The sides are 1 X 12. He uses untreated wood and he keeps his entrance holes standard as well. He drills six holes at the end of the hive with a hand drill. Because he moves these hives, he has a hand grip on each hive which is simply a top bar turned sideways and nailed to the end. The floor is a 10" board (which we know is actually about a 9.75" board). He puts a cleat at the front of the hive to fill in the space between the first top bar and the end of the hive.. He paints his hives with paint rollers rather than brushes.

His top bars are 1 3/8" wide. He cuts starter strips for his top bars that are the same width (1 3/8"). He waxes these in with a dipper of melted wax - he made the dipper by cutting down a plastic cup and melting it slightly to form a pouring spout. He attached a dowel for a handle.

Note: This man is very handy and inventive. He makes all of his own equipment in a small tool shed. He showed us the stacks and stacks of wooden end boards and sides as he worked on putting together some 200 hives over the winter.

His slides are his own and although I took pictures of many of them for my own learning, I am only going to share the one below. The top bars are upturned so that you can see the starter strip. This is a 3 foot hive with 22 top bars. Since beekeepers have been known to lose fingers ripping top bars, I asked him how he got them cut and he gets a sheltered workshop to do them for him.



Very, very generously after his talk at EAS, he stayed in the hall and spoke to a number of us for about another hour afterwards.



He uses roofing tin as his roof. He says that if you don't have a good enough roof the combs drop off of the top bars (which explains why my top bar hive has comb lying on the SBB at the bottom.) He also said that bees won't stay in a top bar hive unless you have some old comb that is drawn to help the bees want to stay in the box (which is what finally worked in mine).


He nails the roofing tin to 2X4s to allow ventilation in the hive.  I used that corrugated white plastic but it wasn't enough insulation to protect the hive from the intense Atlanta heat this summer.  I went to our big box stores in Atlanta and they don't carry roofing tin.  Maybe I can buy some in the mountains at the hardware store there.

The notch you can see on the edge of the roof is for anchoring the rope he uses to tie down the top.
He cuts the tin section so that it can have an overlap the length of his hand.  He demonstrated how he measures it with his hand when he puts the top back on the hive.


Then he begins the tying down process.  He uses the notch cut in each end of the tin roof to anchor the tie.




He is very efficient so he quickly throws the rope to the opposite side.  He has this down to a fine science.






He has a screw eye on the end of the hive through which to tie the top down.














The hive is now secured until the next time.  (Don't you love his hat and jumpsuit - he said nobody recognized him on his wedding day because he didn't have it on!)

He plugs his entrances with pieces of sponge rather than trying to find a cork that will fit - like I said he is quite inventive.

I learned so much from Wyatt Mangum at EAS.  He was the highlight of the conference for me.

As I was chatting with him, up came my buddy from the Southeastern Organic Beekeepers Conference where we both were presenters:  Sam Comfort - my other top bar hero.

  1. Did he mention how hard it was to get the combs out of the stick & telephone wire contraption? It looks like you could detach it and you could roll down the sides, if the comb wasn't attached too much.

  2. The bees grow their comb from the top bar and don't attach it to the sides. They leave bee space around for them to move. I do think occasionally they stick it to the sides but for the most part they do not. If they do, then you cut it off of the sides with the hive tool.

    I've noticed some attachment to the sides in my TBH. I use wooden clay tools to cut the sides very slowly so bees can get out of the way. The clay tools aren't so sharp and don't seem to damage bees so much.

  4. Ah ok, that's neat.

  5. Very cool! I'm not sure what I would do with roofing tin, but hopefully I can put together something similar and try my hand at top bar hives next year.

      for the roof on my top bar hive, I use political signs. I have two hives. One has an ached roof, the other has an almost flat roof. So far they both seem to work equally well.
      I have not tied mine down just because I am lazy, but do plan to do so one day using a screw and a loop of wire. So far the wind has not blown the roof off.

  6. I've been pondering trying a top-bar hive, because I hate how I end up squashing bees when I stack and unstack the Langstroth boxes.

    (I rather like that straw hat.)

  8. Hi Linda -
    This is such a great synopsis of Wyatt's talk this summer at EAS in Boone!

    Not only was the talk good, and informative, the ad-lib session in the hallway afterward was fun too.

    I really love the intense focus that Wyatt puts into his beekeeping, and you have to say - he's RESOURCEFUL in capital letters!

    What Gary is implying that the weed-stalk top-bar hive is difficult to open is absolutely false.

    These weed-stalk hives are easy to open if you know how to work with them. I made my first top-bar hive from similar material back in the 1980's and enjoy working with these hives. You open these hives like my other top-bar hives made from wide board. For more information see

    Kind Regards,

  10. Sam is awesome! Can't wait to see him again after his summer up north. "The Comfort Zone" and I was just as thrilled that he liked my wife's kombucha. He was brewing even before the bees!

  11. IMHO the lid of the TBH is the most neglected. That's why with my FL Style TBH the fully insulated, gabled hinged lid/cover/roof is key to them being brood machines in the hot urban rooftop apiary.

  12. Has Dr Magnum or anyone else experimented with shorter widths of foundation on the top bar? I am wondering if 1/2" or 3/4" strips would work as well? My thoughts are that when I harvest honey by cutting the comb off I wouldn't be leaving such a large strip.

  13. Sorry for the typo, should have been Dr. Mangum
