Beekeepers are going through large challenges, from pests comparable to varroa and tracheal mites and from the mysterious however much more devastating phenomenon generally known as Colony Collapse Dysfunction (CCD). But in backyards and on rooftops everywhere in the world, bees are being raised efficiently, even with out antibiotics, miticides, or different chemical substances. An increasing number of organically minded beekeepers at the moment are utilizing top-bar hives, during which the form of the inside resembles a hole log.
The next is an excerpt from Prime-Bar Beekeeping by Les Crowder and Heather Harrell. It has been tailored for the online.

Usually I’m requested why I made the transition away from Langstroth hives to top-bar hives. You will need to be aware that a lot of what we do as beekeepers would be the identical it doesn’t matter what sort of beehive we use, however there are vital variations in administration, relying on hive design.
My major curiosity as a beekeeper has been to maintain bees organically. The agricultural world has change into more and more toxic, each to the earth and to the individuals consuming the merchandise. Though natural requirements for beekeeping differ from one nation to a different, they often advocate that beekeepers use hives constituted of pure supplies that aren’t handled with any chemical substances. In addition they generally advocate that bees construct their very own combs, forage in an unsprayed setting, will not be fed sugar syrup or pollen substitutes, and will not be handled with chemical inputs of any sort. The highest-bar hive simply accommodates natural necessities. It may be constructed by a beekeeper for about $30 to $40 out of untreated wooden, and even made out of wildcrafted supplies comparable to willow or bamboo. I’ve even made a hive out of adobe mud. The inside of a top-bar hive mimics a hole log, and the top-bar beekeeping bees can draw out their combs in no matter method they select.The highest-bar hive is lengthy lasting and 100% biodegradable.

Certainly one of my preliminary causes for transitioning away from Langstroth hives was the necessity to retailer combs over winter. Langstroth hives have bins referred to as supers which can be positioned above the brood field for honey storage. As soon as the honey harvest is over for the season, supers are saved for the winter within the hope of preserving the combs for the next season. The storage of supers is an issue as a result of wax moths and mice will eat and destroy the combs. In industrial operations, supers are fumigated with paradichlorobenzene to maintain these pests away. Paradichlorobenzene, the chemical utilized in mothballs, is a recognized carcinogen that’s absorbed by beeswax. The combs within the supers are handled with this chemical after which positioned again into the beehives within the springtime to be refilled with honey. In a top-bar hive, nonetheless, there isn’t any have to retailer combs by means of the winter, which eliminates each the issue and its chemical answer.
Langstroth hives are used at the side of sheets of wax or plastic referred to as basis. These sheets are imprinted with a delegated cell dimension, one which’s designed to maximise honey manufacturing. Though basis was made solely from beeswax, industrial beekeepers are turning to the plastic basis as a longer-lasting and subsequently extra economical alternative for his or her companies. Sadly, this plastic finally ends up as an industrial waste product when it’s now not helpful. The predetermined cell dimension of basis additionally presents a matter of debate throughout the natural beekeeping neighborhood.
In a pure setting, honeybees will draw out varied sizes of cells relying on the wants of the hive, typically utilizing a wide range of cell sizes on one comb. Bees generally will construct bigger cells on the prime of a comb and smaller cells on the backside of the comb. The brood cell dimension additionally adjustments barely over the course of a season, and the ensuing physiology of the rising bees shifts to correlate with this alteration. Bees born from bigger cells are correspondingly bigger and have extra fats our bodies. Research have proven that substances within the fats our bodies have an effect on employee longevity and that these substances work together with brood pheromones.1 Bees born from smaller cells, in distinction, are smaller and present better resistance to varroa mite.2 In top-bar hives, the bees are free to fluctuate their cell sizes to fulfill the altering calls for of the hive, and there’s neither the expense nor the waste of plastic basis. The administration of hygiene and illness was additionally an integral a part of my alternative to make use of top-bar hives.
With the Langstroth system, honey is extracted from the comb by centrifugal drive, which leaves the beeswax combs intact. This enables the beekeeper to place them again into the hive to be refilled by the bees. For max honey manufacturing, this extraction course of makes quite a lot of financial sense. The bees don’t need to rebuild the comb, which makes use of up loads of the sources of the hive. The beekeeper thus earnings from having extra honey at a sooner charge of harvest. Nevertheless, the tendency in massive industrial operations is to maintain placing combs again into the hive after they’ve change into a possible well being danger for the bees in an effort to get as a lot use from them as potential earlier than they’re discarded.
Every time the queen bee lays an egg in a cell, the bee larva traces the cell with its cocoon throughout pupation. When the brand new grownup bee emerges, the cocoon stays contained in the cell, is cleaned out, and a brand new egg is laid. When the following grownup bee develops, a second layer of cocoon is left behind, can be cleaned out, and the method continues. As time goes on, the cell dimension will get smaller and smaller, and the comb will get blacker and blacker because of a buildup of cocoons, propolis, and fecal matter contained in the partitions of the cells. The bees born inside these darker cells are smaller, and the hygiene of the hive ultimately turns into compromised because of a better degree of pathogens. The temptation for industrial Langstroth operations to proceed to make use of previous black combs is nice, as the price of changing combs means the price of shopping for extra basis, in addition to dropping money and time on having the bees construct recent combs.
In top-bar hive administration, quite a lot of consideration and care is given to biking out previous darkish combs. They routinely are moved to the again of the brood nest in order that they might be crammed with honey and culled. The honey is harvested by taking the

complete comb off the bar and crushing it, permitting the honey to empty out by means of a colander. The bees then have to attract out recent comb to interchange the comb that has been harvested. Though many Langstroth hive advocates imagine that it’s detrimental to require the bees to make extra beeswax frequently, the bees profit from the common conversion of honey to beeswax. It workouts their wax-making glands, which retains their glandular programs lively and wholesome. Beeswax absorbs and holds oil- and fat-soluble toxins, that are sadly plentiful in our present setting. As these toxins construct up contained in the hive, it turns into an more and more poisonous setting for the bees to reside in. Constantly rotating and culling combs retains the hive wholesome as a result of it removes wax-soluble toxins and cleanses the hive by means of regeneration.
Lastly, the Langstroth system requires some pricey gear. To be able to produce honey in any quantity, an extractor is a required expense. Extractors are stainless-steel machines designed to tug the honey gently out of the combs by means of centrifugal drive. Though extractors save time throughout honey harvest and protect the combs, they’ve their drawbacks as effectively. Beekeepers who use an extractor are likely to delay honey harvest till there’s a massive batch of honey to extract. The labor required to make use of and clear the machine merely isn’t justified with small batches of honey. In distinction, as a producer of varietal honeys, it’s in my finest curiosity to reap honey after every plant circulate, regardless of how massive, in order that I can bottle and promote distinctive flavors.
Cons of Prime-Bar Beekeeping
The highest-bar system definitely has some disadvantages, the primary one being that top-bar hives require a excessive degree of ability and confidence from the start beekeeper. The likelihood for cross-combing is nice, and as soon as a top-bar hive has change into cross-combed, it may be a really daunting activity to scrub up. Cross-combing occurs when the bees draw their combs at odd angles to the highest bars, generally spanning many bars directly, which causes the comb to drop and break when the hive is opened. The primary ability of top-bar hive administration entails spacing the combs in order that the bees shouldn’t have an opportunity to cross-comb. On heavy honey flows in late summer time, when there are a better variety of bees within the hive, it may be troublesome to remain on prime of administration, particularly if a beekeeper has a lot of hives. This makes top-bar hives a probably discouraging alternative for industrial beekeeping. It is usually troublesome to load and stack top-bar hives for large-scale pollination.
One other clear disadvantage to top-bar hives is that the bees need to construct brand-new combs each time honey is harvested, which reduces honey manufacturing. The bees devour 9 to 11 kilos (4–5 kg) of honey to supply each 1 pound (0.45 kg) of beeswax, so the development of recent combs detracts from the quantity of honey that will get saved within the hive. I experimented with 5 top-bar hives and 5 Langstroth hives one yr and located that, on common, the top-bar hives produced 20 % much less honey and 6 occasions as a lot beeswax because the Langstroth hives. Many top-bar beekeepers make the most of these larger wax yields by making candles, salves, and balms to diversify their companies. The financial benefit of better wax yields might effectively offset the drawback of decrease honey manufacturing, relying on how beekeepers select to market their wax merchandise.
The pure top-bar motion has appealed primarily to residence and pastime operators who’ve the time and curiosity in maintaining bees intensively. Though there are some industrial top-bar operations throughout the US, they’re a small minority in contrast with the variety of Langstroth operations. Most beekeeping publications are designed to serve the Langstroth neighborhood, and there’s quite a lot of assist for freshmen. Though there are assist programs for top-bar hive fans, they are typically small teams oriented towards energetic discussions of hive design and home-built programs for harvest and wax utilization. Fortunately, that is slowly altering, aided by the Web and a rising physique of sources for top-bar hive beekeepers.
