Details of the Taranov split

The Olympia beekeeper who submitted the photos of splitting a Langstroth with a Taranov board, Dave Hurd, sent in some details based on reader questions. He did a nice job explaining his method, so I’m presenting it as today’s post. Once again thanks, Dave, for all your input and your great photos.

I can add a little more info about my split experience. On the afternoon of 4/28 (two weeks ago) we were having some usually warm weather and the bees were flying so I thought it would be a handy time to start a HopGuard treatment. I first installed the strips in my nuc and then moved onto my triple. I put strips in the top box, then as I lifted it off I saw a couple of capped swarm cells along the bottom of the frames. I carefully lowered the box back into place and closed the hive. That was probably around 2:30.

At that point I was sure that the hive had either already recently swarmed or was just about to, and decided to make the split immediately in case the girls hadn’t bolted yet. Having read Rusty’s excellent description of the Taranov method I knew what I needed to do (run back into the house to read it again), so I came up with the materials to fabricate my board and put it together, got a nice floral print sheet from my wife, and got set up.

As I was placing the board and sheet I noticed right away that through some adrenalin induced measurement error the lip of the board was about 1.5″ too high, so I slipped a couple of 2x4s under the hive to even them up. It was probably about 3:00 when the apparatus was assembled, in place, and ready for action.

I started shaking frames working from the top down, stacking the emptied boxes on the top cover. When I got to the bottom box I pulled, shook, and replaced the frames leaving the box in place.

Per the instructions I made sure to carefully brush the bees from frames with swarm cells to protect the new queen. For the other frames it only took one or two firm shakes to drop the bees onto the sheet. The whole process proceeded very quickly; after 20 minutes the hive was as empty. I spotted the marked queen midway through the middle box as she fell on the sheet.

At 5:00 all of the bees were either back in the hive, clustered under the board, or out foraging. By 5:05 the cluster was in a new home sipping sweet syrup. This was a brand new box, with brand new frames of brand new foundation; no queen cells added.

Today, two weeks later, the old marked queen is still in the new hive with quite a bit of eggs, brood, and capped brood. They seem to be doing well; in fact they seemed a little crowded so I added a second box on top of the first. I’ll check the old hive to make sure there are eggs next week, and if not I’ll requeen it from my nuc.

As far as needing help, I did this all on my own and it was, in hindsight, not a big deal work-wise. I will admit to being a little panicky during the process because, well, that was a lot of bees! I was much relieved when I saw the queen and knew that I had caught it in time. I don’t think it could have gone much faster if I’d have had help; but there would have been someone to hold the video camera . . .

Another take on Taranov

A beekeeper here in Olympia, Dave Hurd, sent me the following photos of splitting a hive with a Taranov board. His design for the ramp is slightly different than my own but the principle is the same. Because he split a Langstroth rather than a top-bar hive, I thought you might enjoy seeing his photos.

Based on these two examples, it’s hard to say if all bees are this smart or if Olympia bees are smarter than most. Hmm…

Anyway, in his comment, Dave wrote:

I’m an Olympia, WA beekeeper (well, I keep most of them) and today is my one-year bee anniversary! . . . I wanted to let you know that I detected impending swarmification (my word) a little over a week ago in my triple deep and so used this method to split the hive.

It was astonishing. It was also unnerving to be shaking sooo many bees out onto the sheet. The carpet of bees marched itself up the ramp and split just like clockwork. . . . My board prototype is a little different than yours but performed admirably. Both the triple and the new colony seem to be doing well, though I don’t think I’ll open them to snoop for eggs for a while yet. . . .

I crafted my board out of an 8-frame bottom board, plywood scraps for side stands, a chunk of 2×6 attached to the bottom for ballast, and 1.5″ wide piece of leather-backed fuzzy material that I cut off of an ice scraper cuff that I then stapled to a piece of 1×2. I figure by the time winter comes back my wife won’t recall exactly how long that ice scraper cuff was. . . .

Thanks, Dave, for your description and some really great photographs!

The great divide: a Taranov split

I recognized the cacophony coming from my top-bar hive. The insistent roar told me those bees were ready to swarm. They were milling about, climbing up the sides of the hive, flying but not foraging.

I had just returned from a week on the road and didn’t feel like messing with bees, but they were hard to ignore. I watched them for a long while, then asked them (nicely) not to swarm until tomorrow.

On Friday I got up early with the intention of taking a shook swarm from that hive. It’s my only top-bar hive, so I have nothing to split it into. But as I was getting ready, I recalled a conversation I had just had with Karessa of Nectar Bee Supply in Corvallis. She had read my post on the Taranov board and asked if I had ever tried it. Suddenly I knew I had perfect conditions for a test—a hive that was going to swarm any minute.

So I printed instructions from my own website and went through the steps one by one. By the time I was set up and ready to begin I decided there was no way this could possibly work. What on earth made me believe I could shake all the bees out of the hive and expect them to divide themselves into two camps: the swarmers and the stayers? This Russian guy was insane.

But at that point, I decided to keep going. One by one I took out every frame, inspected it for the queen (which I never found), and shook the bees onto the sheet. Like a scene from Harry Potter, all the bees marched up the ramp and divided into two groups. They behaved like a swarm, very gentle and completely non-aggressive.

Now, two days later, everyone seems well settled in. I saw no crossover between the two hives and both have good populations. All the swarming behavior ceased. I no longer think the Russian guy was nuts; I think he was a genius—and he certainly knew bee behavior. Have a look at the photos below . . . this split was too cool for words.

My husband doesn’t like me to use his radial-arm saw because I might delete an important appendage. He wasn’t home however, so onward and upward. I cut an old piece of plywood the width of the alighting board and another as a brace. I couldn’t find a hinge, so I used an angle bracket.

Here is the ramp in place. By now, the whole thing seemed ridiculous. After all, what self-respecting bee wouldn’t make the four-inch journey between ramp and home? And why would bees go looking for a rag under the ramp?

I taped the sheet to the ramp. If you try this at home, staple it. The tape eventually released under the weight of all the bees.

How to make a vertical split

This is one of the easiest ways to split a colony and, if things go wrong, it is easy to undo. I call it a vertical split, but some call it a top split, an over/under split, or a top-and-bottom split. Like all the other splits I have described, it is just a variation on the basic principles of splitting a hive.

Here are the steps for making a vertical split:

  1. Remove two to three frames of brood from the colony you want to split and place these frames in the center of an empty brood box. As with any split, the brood frames should contain eggs, newly hatched larvae, and capped brood—all of it covered with nurse bees.
  2. Next to the brood frames, add at least one frame containing pollen and one containing honey.
  3. Fill out the rest of the box with frames of drawn comb or foundation.
  4. Also backfill the original brood box with frames of drawn comb or foundation.
  5. Place a double-screened board on top of the original brood box.
  6. Put the opening of the double-screen board on the back side of the original hive, and make sure the opening leads to the upper brood box.
  7. Place the new split on top of the double-screen board.
  8. Place the hive cover on top of the new split.

Other considerations:

If you are going to introduce a queen to the new split, wait a few hours or overnight before introducing the queen in her cage. Don’t introduce a queen to the split unless you are certain the original queen is not in the split.

If you are expecting the split to produce its own queen, look for queen cells in three or four days. If there are no queen cells, you may add another frame of eggs and newly-hatched larvae to the center of the brood nest.

As with any split, feeding is optional and depends on how many frames of honey the split has, the weather, the availability of forage, and the size of the split.

Once the new queen (either introduced or natural) begins laying, you can move the split off the parent hive to its final location.

Advantages of the vertical split:

  • The double-screen board allows heat to move from the established colony into the split. This means splits can be done earlier in the year.
  • This type of split can be done quickly with little planning. If during a hive inspection you find queen cells, you can put them in a box above the double-screen board and leave the original queen below. You will have a new queen in days.
  • If the split doesn’t take for some reason, you can smoke the hive and remove the double screen. The hive will reunite quickly with little disruption.

How to make a split

In simplest terms, a split is made by dividing an existing colony into two or more parts. Many variations exist. In fact, the methods of making splits—and the reasons for making them—are as varied as the beekeepers who do them.

The most common reasons for making splits are to:

While there are many different ways to do a split, you must follow of number of guidelines if you expect success.

  • Use overwintered colonies. A brand new colony from a nuc or package does not have the resources needed for a good split.
  • Use strong colonies. If you split a weak colony, you get even weaker ones—if any. The larger the colony, the better your chance of success.
  • A split will need a queen provided for it or it must be able to produce a queen.
  • If you expect a split to produce a queen, drones must be available. The more drones actively flying, the better.
  • If you expect a split to produce a queen, it must also have fresh eggs or newly hatched larvae, plenty of nurse bees, pollen, and honey.
  • The brood nest of a split must imitate normal nest structure—worker brood in the center, drone brood on the outer edges of the worker brood, pollen on both sides of the nest, honey on both sides of the pollen.
  • A split needs protection from robbers in the form of a reduced entrance or robbing screen.

Even when you do everything right, a split won’t always succeed. If after a few days there is no sign of queen rearing, you will need to add more fresh eggs or newly hatched larvae. If it fails a second time, it is best to recombine the split with another hive.

The easiest type of split is made by using a populous hive where the brood nest spans two brood boxes. The beekeeper simply takes off the top box and puts it on its own bottom board, adds a lid, and walks away.

But even that simple form of split requires some attention for success, especially if you don’t know where the queen is:

Finally, here are some additional considerations, regardless of the type of split you make:

  • When splitting the hive and dividing resources, concentrate on the number nurse bees, not the number of foragers. If you are splitting within your own apiary (or within a two-mile radius of it) the foragers will return to their original hive or to the split that contains their queen. Try to ignore these foragers and concentrate on the number of nurse bees that will be in each split. The nurses are the key to making the split work.
  • You can put splits side-by-side, no problem. Just remember that for a long time, the part without a queen will look like no one is home. Gradually, as nurses become foragers, the discrepancy will decrease. Don’t let the number of foragers in the one part freak you out. If the split is raising a queen, everything is working according to plan.
  • Remember to provide adequate honey (or syrup) and pollen (or pollen supplement), especially to the part with few foragers. Since that part doesn’t have a workforce collecting materials from the field, it may need extra supplies to raise that first batch of brood.

Even though it sounds complex, don’t be afraid to try this. It works amazingly well, allowing you to both increase the number of hives and raise your own local queens. At the bottom of the page on the “Splits” tab on the main menu are links to several different types of splits you can try, and later this week I will be adding another.
