a couple of reasons I personally prefer Warré hives over Langstroths and other frame hives:
no frames. for frames to serve the purpose of easy harvest and removal, there must be a space between the outside of the frame and the wall of the hive. that involves creating a dead space that is useless to the bees. if we accept that bees must expend resources to maintain the atmosphere of their hive, then it follows that dead space leads to expenditure of resources without a corresponding gain for the bees. that space at the edge of the hive also provides a hidey-hole for organisms detrimental to the heath of the colony. these include pests such as wax moths and microorganisms such as mold.
further, to prevent the bees from fixing the frames to the hive walls and other frames by use of bridging comb, the hive must be opened regularly to remove that comb. opening a hive dramatically disturbs the atmosphere of the hive, and it can take from two to four days for that atmosphere to return to homeostasis. in the mean time, the pheromones used by the bees for communication inside the hive have been confused by the disturbance. alarm pheromones are secreted, which act in a similar fashion to the human sympathetic nervous system, which is to say that they are alert for danger and generally stressed out (metaphorically speaking). such alarm pheromones are also attractive to small hive beetles, and possibly other honey bee pests.
the purpose of frames being to ease manipulation of combs, such manipulation is made more likely by the use of frames. such manipulation includes checkerboarding, destruction of drone brood, swarm suppression by destroying queen cells,
et cetera. these interventions interrupt and disturb the bees' expected life cycle, weakening the colony and making it more dependent on further intervention in a positive feedback loop.
nadir instead of super. supering is the practice of adding empty hive bodies to the top of a hive. as far as I can tell, supering is the primary practice that leads to larger honey harvests from Langstroth hives compared to less intervention-oriented hives. when a colony moves into a cavity, they generally begin building comb from the top down and fill that comb first with brood, and later with honey and pollen as the brood nest is expanded downward. for there to be empty space, or empty comb, at the top of a nest cavity is not a situation that honey bees are likely to encounter in a wild or feral hive, and they respond to it with panic. that panic takes the form of a desperate race to fill an empty space or empty comb above with honey. production is increased, but not without consequences for the health of the colony.
in regions with very intense nectar flows, I believe that supering is appropriate to prevent honey-binding. otherwise, I believe that it has a lot in common with the use of hormones to increase
milk production in
dairy animals.
and a couple of reasons I prefer The People's Hive to horizontal top bar hives:
my objections to horizontal top bar hives have largely to do with personal preference and regional conditions rather than the philosophical disapproval I have for most frame hives. for the folks who have success with horizontal top bar hives and enjoy using them, I'm all for their continued use.
ease of use. horizontal top bar hives (hTBHs) frequently require a fair amount of manipulation for them to thrive. one example is the prevention of honey-binding. when flows are strong, honey combs must be harvested frequently to make room for more nectar. otherwise, nectar will displace brood and the colony's population will plummet.
another manipulation that is frequently required is ensuring that the winter cluster begins the winter at one end of the hive or the other. if the cluster begins the winter in the middle of the hive and moves to one end as stores are consumed, they will starve even though there may be plenty of honey at the other end.
it
should be noted that hive manipulations in hTBHs are much less disturbing to the colony than in frame hives because the top bars largely prevent disruption of the hive atmosphere, even when the roof is off the hive. disruption is limited to the combs that are moved, while the rest of the atmosphere largely remains intact. so my objection to these interventions is because I don't want to have to fuss with the hive, not because they are particularly detrimental to the bees.
climate. it seems to me that most of the success stories I hear about hTBHs are from regions with milder and drier winters than where I live and keep bees. my own experiences with hTBHs have always ended with the failure of the colony. others relatively nearby have had success with this style, so my
experience could be a fluke, or I could have been doing something wrong. the winter cluster issue I mentioned above wouldn't be a problem in warmer regions because less honey is required by the colony to overwinter. it's more important here, because winters are sometimes short and mild, and sometimes long and less mild. springs are also sometimes wet
enough that bees are unable to forage extensively until May or June, so stores are very important.
modular design. Warré hives are easy to expand and contract with the size of the colony, while the size of hTBHs is pretty much fixed. a follower board may be used to reduce the size of the hive, but not to expand it. if a colony is really thriving, I can add more boxes to the bottom of the hive to accommodate them. when the population declines over the winter, boxes can be removed to reduce the volume the colony has to heat in cold weather.
ease of harvest. I harvest whole boxes at once instead of individual combs. after a box is removed, I can leave it until I have time to press the comb. I don't have to process any combs immediately, and I don't have to build a storage device to keep the combs upright or intact. I just have to protect them from robbing and wax moths.
cross comb. because I harvest whole boxes, cross comb and burr comb aren't a problem. if the bees want to build their combs in spirals, I have no objections. when it comes time to harvest, I will be removing the combs and pressing them. the combs will be destroyed anyway, and I won't be removing them individually, so their shape is immaterial. in a hTBH, a comb that isn't straight can cause the beekeeper some serious headaches, and may well cause problems for the colony if combs need to be moved. I recently helped a friend do a postmortem on a hTBH, and the combs were badly crossed. the shapes were beautiful, but it would have been impossible to harvest or move a comb without seriously compromising the integrity of the hive.
I've gone on too long. for me, those are the main ideas. I do have further objections to many standard frame hive practices, but those are
practices and aren't inherent in the design, so I won't subject you all to them just now.
in the end, your choice of hives will be informed by your own values. if somebody tells you the hive or hives you choose are bad, it might be time to change the subject or find somebody else to talk to.
and David Heaf's book,
The Bee-friendly Beekeeper: A sustainable approach, is good. David's writing is accessible, and I really like his attention to the
energy and other resources involved in beekeeping choices.
