Midlands Beekeeping Calendar for December

As always, all beekeeping is local. Here’s my beekeeping calendar for the South Carolina Midlands for the month of December:

If you thought the beekeeping season was over you would be incorrect. The successful beekeeper continues his/her efforts over the winter to have success in the coming year.

Hive checks this month are tied directly to outside temperatures. Do not disturb the brood chamber or break propolis seals around boxes unless absolutely necessary. On a warm day with temperatures in the 60’s you may briefly remove the inner cover and view down between the frames. Try to not be too disruptive in order to allow them to keep their house (brood box) in order for winter. Use of a stethoscope or an ear against the side of the hive will often tell you all is well inside.

1) Clean, paint, repair equipment, assemble new equipment, build more hive stands, make some of those time saver gadgets, and replace any bad equipment. Remember, when spring arrives you will be very busy and won’t have as much time to construct needed hive bodies, build frames, wire (or wax) foundation, or build stands.

2) Check for excessive moisture in the hive. Lift the cover and note for wetness or mold indicating excess moisture. As needed, ventilate hives with a 1/16th inch crack at the front of the inner cover to prevent condensation and mold. Alternatively, many beekeepers maintain an upper entrance in their inner cover. Other methods of controlling excess humidity in the hive is by using a quilt box above the inner cover or using insulated outer covers. Typically we do not wrap our hives in the Midlands as our winters are not harsh. Remember, the bees can keep themselves warm if they have enough bees and enough food stores. It’s the moisture we are focused on preventing.

3) During winter, it is important to tilt the entire hive forward slightly with a shim placed under the hive in the back. This is especially true for those hives with solid bottom boards. A driving rain can pool water inside the hive and, coupled with lower temperatures and winter debris on the floor, will chill the bees. To a lesser extent we do this to allow condensation that forms above the cluster to run forward and down the front of the inside of the hive, preventing it from dripping on the bees. While this helps reduce condensation from above, it should not be the sole method of preventing overhead moisture (see # 2 above).

4) Continue to assess stores. Continue to heft the back of your hives to check for weight. (Not having to open the hives in the cold weather is why you learned this method earlier in the year to assess food stores.)

5) If needed, feed using a low moisture method such as a candy board or fondant. Another method of winter feeding that also reduces moisture in the hive is the Mountain Camp method.

6) Order packages, nucleus hives, and queens for delivery mid to late March or as early as possible for your area.

7) Review and evaluate how well your bee colonies performed this year and make decisions on how to improve your operation, particularly regarding disease management and pest control such as Varroa mites, small hive beetles, and wax moths. Document your findings in your beekeeping journal.

8) Plan now for changes you’re going to implement next season. Will you explore making splits, raising queens, increasing your honey yield, producing nucleus hives, or pollinating crops for income? Set goals now and prepare for next year’s success.

9) Call, visit, or write farmers or landowners where you’d like to place hives for out yards next spring. Use Google Maps to scout likely locations.

10) Renew your membership in your local Beekeepers Association. Attend local club meetings. Register for your state’s Spring Beekeepers conference.

11) Scout trees and other locations for bait hive placement and prepare swarms traps (bait hives). Read Bait Hives and Swarm Traps by McCartney Taylor, available for checkout from the Mid-State Beekeepers library.

12) Construct a swarm capture bucket for those spring swarm calls that inevitably come during swarm season.

13) Build a nucleus hive now to keep in your car or truck for community swarm captures next spring. These small hives are also very handy to have on hand when you see swarm cells in your own hives and need to move a queen or queen cells to capitalize on, or survive, an unexpected reproductive event.

14) Order or ask Santa for a copy of that beekeeping book you’ve been wanting to read. Read some every day.

15) If, for some reason you have not yet treated for Varroa, this time of year presents the Midlands with as close to a broodless period as we get. A cheap, economical, quick and easy, method of Varroa treatment during this broodless period is the oxalic acid dribble. Read about how it’s performed here: Once a Year Opportunity to Save on Varroa Treatment.

16) December is an excellent month for selling honey. Farmer’s markets, holiday festivals, and other events are great places to sell your golden treasure.

17) Celebrate Lorenzo Langstroth’s birthday on December 25.

The above are general guidelines for the average bee colony in the Midlands of South Carolina. We all have hives that may be outperforming the average. We also have colonies that underperform the average. Use your judgement in making changes suggested here. Beekeeping is an art as well as a science. Only you know the many, many particulars associated with your physical hives as well as the general health and population of your colonies.

Protecting your Drawn Comb by sassafrasbeefarm

First and second year beekeepers! You may be pulling honey supers, extracting, and have empty drawn comb. Or maybe a hive failed leaving you with drawn comb. Drawn comb is gold! You can always buy more bees, catch a swarm, make a split, or otherwise replace bees. But drawn comb can not be purchased. Having drawn comb exponentially increases a colony’s productivity versus starting on foundation. A spring package on drawn comb typically makes honey the same year.

Beekeepers must protect their drawn comb from wax moths which will take every opportunity to destroy your bee’s legacy.

Here are a few excerpts from an email I sent discussing protecting drawn comb:

<begin>

Be thankful they are on plastic foundation. Otherwise you often have to replace the foundation. And if they are in wooden frames wax moths will actually bore holes in the wood as well. On plastic you can scrape it off and re-coat with wax for next year.

As for the freezer: You can Google wax moth, life cycle, etc and find some research. It’s like anything else, dependent on temperature and length of time of exposure. Two days may be sufficient IF your freezer is at 0 degrees F. If your freezer is kept at 10 degrees F it may take 6 days. And if at 20 degrees F it may take 14 days. (These are guesses but you get the idea.)

There is a temperature range for wax moth reproduction. When the temperatures get cool enough outside they are no longer a threat. I guess there are some people with a limited number of frames who can store them in the freezer until the weather cools enough.

Every year we get posts on the local discussion board with pictures saying they froze the comb for X number of days and then placed in in a Tupperware or other container and under the house or some similar dark place only to find the comb destroyed by spring. Last year in bee school a member of the class asked me about this specifically and said if he placed them in the freezer for days and then immediately placed it in lawn trash bags and sealed them completely and absolutely shouldn’t that work? I told him that “in theory” his plan would work but my experience is some eggs will hatch and if conditions are right they will destroy his comb.

On Para-moth (paradichlorobenzene) crystals: They do work but it is not a one and done application. Use them generously. Periodically check them through the storage period and replenish them as needed. They do “melt” as they release their gas into the supers. I’ve seen some people tape the edges of the supers to make a gas seal. Unfortunately this dark, sealed environment is also ideal for the moths when the para-moth dissolves and no longer provides protection.

Using open air and light: I did this one year with good success. I simply have too many supers now. Also, anything I place outside now is subject to squirrels who seem to like the comb, pollen, honey residuals.

BT (bacillus thuringiensis aizawa): Reports are, this works well. As you know it used to be a recognized method of wax moth control in bee hives but the company decided to not renew it’s license for use as such. Data used to be on the Clemson site. BT for use on crops is recognized as non chemical, organic bio control method and approved for use on organic crops. While an approved organic pest control method, it is no longer legal for use in bee hives.

I have a friend that uses BT and sprays the comb coming out of the extractor.

If you do not protect your comb from wax moths don’t despair, I understand the larvae are great as fishing bait.

Early Spring? Or not…

Early Swarms 2016

I’m not at all convinced the warm climate we are seeing this winter is here to stay. But I’m not sure the bees agree with my weather predictions either. Watching the landing boards with foragers in full pollen collection mode and brief inspections tell me that some colonies are already in full tilt brood production.

What does this mean for the beekeeper?

Well, it means lots of excitement watching them grow at a rate that is phenomenal. By this time next month either you will have made room for the extra bees and managed them for swarming or you may be looking up in the trees for half of your work force.

Or it could be more dire. Winter food stores up until this point have been steadily declining at a gradual but predictable rate. What happens now when the queen is at full egg laying (brood producing) coupled with a growing workforce? Well, between increased consumption of ever more house bees and foragers, plus trying to feed thousands of larvae, the food stores decline can no longer be graphed as a straight line. Now it is a sharp spike upward!

Beginning now is when the beekeeper needs to remember to lift the backs of their hives. And on those pretty days when you get into them to ooh-ahh at their numbers and beauty, look and assess their nectar stores. December and January saw a full pantry with slow, steady declines, but brood rearing brings on food demands that dwarf the demands of fall and early winter.

And a final scare for you. It’s quite a curiosity that starved bees don’t slowly decline due to lack of food. No, for them, it’s the Three Musketeers: “All for one and one for all,” meaning they’ll go down together if they run out of food. One day they are all fed, the next, well…not.

Feeding the bees pollen substitute

Some things don’t change much year to year in beekeeping. At least not the chores. There is some comfort in the routine. This year is much like last. Building boxes, cleaning frames, painting and maintenance. And building bees for the spring. ~sassafrasbeefarm

This time of year can be as busy for the beekeeper as the spring nectar flow period. But now it’s all about preparation. My experience, since beginning this beekeeping journey, is that there is never enough time during the nectar flow. In fact, time becomes precious even before the nectar flow with the need to rotate hive bodies or employ other swarm reducing measures, placement of swarm traps, movement of hives to out yards, making splits, and lots of last minute surprises.

So, here are few pictures of what I occupy myself with during this so called off season:

Order queen pen and my favorite markers to write on the hives.

Making sugar cakes for the tops of the hives.

Adding extra wax to plastic frames.

Collecting and bagging pine straw for my smoker.

 

Building boxes, bottom boards, and tops.

Adding some color to the entrance reducers.

Painting entrances to the queen mating nucs

This is Advantech – a new material that resists weathering.

Painting everything. Three coats!

Joy! I found three 50 pound sacks of sugar I had forgotten!

ProVap110 Oxalic Acid Sublimator by sassafrasbeefarm

Product Review:

For Varroa mite control, I sprung for a ProVap110 this year. I put it through the paces this week and thought I’d report on it here.

View Video Here:

Disclaimer first: Yes, Larry of OxaVap is a friend of mine. We met at a South Carolina Beekeepers Association conference several years ago and hit it off talking bees non stop for the duration of the conference. This was all before oxalic acid was approved for use in the United States. Larry told me then it would be the next big deal in Varroa mite control and apparently he was right as it was approved a couple years later. (Larry also told me where U.S. beekeepers were already ordering vaporizers from across the border in Canada.) Anyway, Larry and I always look forward to conferences and hanging out, telling bee stories when we can.

Before getting the ProVap110 I was using two Varrox, pan type ,vaporizers. Using two really sped up my mite treatments. Duh, twice as fast, right? No, don’t ask me how but everything moved faster and down time between hives was less so I really think I was doing the job in less than half the time than with one.

Recently, Larry suggested I needed to try the ProVap110 but I was resistant due to the issue of needing AC current. He said that most inexpensive car/truck inverters would do the job as it only used 250 watts and 2.2 amps. I checked and Harbor Freight had an inexpensive inverter. But I really wanted to be able to treat without having to drive my truck into sometimes muddy out yards. Larry assured me that a long extension cord run would not be a problem but I resisted and bought a small WEN 1800watt generator. I do plan on buying that inverter as well but the WEN1800w is under 50 pounds and, so far, I really like it and don’t have to worry about getting my truck stuck in a muddy out yard field while vaporizing mites.

One morning this week I oxalic acid vaporized 32 hives in about an hour and 15 minutes. As with the old Varrox, you still have the setup time of placing IPM boards under screened bottom boards to help seal the hive as well as a damp dishcloth across the entrance. I left the WEN1800w generator in the back of my truck and used a 50 ft extension cord. The extension cord had no noticeable effect on the operation as the ProVap performed exactly as the enclosed paperwork stated it would. I will use a 100 ft extension next time to see if that has any effect. The ProVap110 took about 2 to 3 minutes to reach its operating temperature of 230C. The unit adjusts to maintain that temperature throughout its use. I’ll place a link to a video in this post for those who have not seen how it operates. Basically, after it reaches its operating temperature a measured amount of OA is placed in a cup and attached to the ProVap110 while inverted. The nozzle is inserted into a 1/4″ predrilled hole in the hive body and the unit is spun around to its upright position causing the OA to drop into the 230C pan. The temperature readout dropped to approximately 208C when the OA came in contact with the heating unit and immediately began its rise back to 230C. Within about 20 seconds the temperature had returned to 230C and I removed the unit from the hive. An additional “cup” is provided so the user can prepare the dose for the next hive during the 20 second wait. And so it goes hopscotching down the row of hives.

Some things I learned are: 1) Hole placement is more critical than I first expected. I had used a homemade template based on the instruction sheet and some of the holes were drilled into handholds which caused me to have to hold the unit in place instead of leaving it to prep the next dose. The instructions say drill the hole 3 to 4 inches up from the bottom . I will drill future holes below the handholds in the lower box – if you use cleats drill well below. You want the vapors to circulate readily once inside the hive so make the hole in that area where the frames are narrow (lower half) to allow for the bees to move around the frame. 2) The tube that sends the vapor into the hive is copper and about 3/4″ in length. That makes sense since it is going into a hive body with a thickness of 3/4″. Longer and it could bottom out on a frame inside. Unrelated to the tube length but I’d like the tube to be made of a harder metal than copper if possible – I am uncomfortable with the possibility of bending the copper tubing. 3) You will need an acid/vapor PPE mask as you will be in close proximity of the OA vapor. There is no getting around this. I currently use a 3M 7502 mask with organic vapor/ acid gas filters – $13.99 on Ebay, and non vented safety goggles – $7.99 Ebay. The mask worked great and I never even got a whiff while standing behind the hive administering the OA vapor. (more on this later)

Some of the nice things about the unit are: 1) Its speed. I usually just stood there behind the hive for 20 seconds and let it do its thing. 2) The plume of vapor into the hive is thick and sudden. The bees don’t have the “warning time” they did with pan type vaporizers to start fanning. Bang, it’s in there and done. Most of the hives didn’t object any more than they did with the pan vaporizer but a couple did. All hives settled down soon afterwards. 3) The almost constant 230C temperature ensures the OA is properly sublimated. I always suspected the gradual warming of the OA with the pan vaporizers may have wasted some of the OA as it was evaporated, boiled off, or was otherwise consumed instead of sublimated thus diminishing the dose. The ProVap110 ensures the OA always hits the pan at exactly 230C. 4) I often lose my biggest and strongest hives over the winter. I’ve always suspected it might be related to inadequate OA treatment reaching the upper boxes. Now I can treat the hive via a 1/4″ hole placed anywhere, in any box, instead of just underneath the hive. And don’t worry about drilling 1/4″ holes in your woodenware, the bees will propolize it soon enough or you can use a golf tee or dowel rod to plug. 5) It would be nice to have a half dozen of the “caps.” to prepare in advance. It’s not essential; that’s just my OCD speaking.

General comments: Most efficient use would necessitate a planned layout of the hives in the bee yard. If you scatter your hives around here and there you’ll waste time in transit. I have basically three different zones in my home yard. This meant driving the truck to three different positions and repositioning the drop cord each time. I think keeping your hives within a 100 foot radius and using a 100 foot drop cord might be ideal. Having plenty of IPM boards available is also a great time saver as transferring them hive to hive is a time waster. Luckily I have plenty to use in case of a severe winter but others may not. The hives with solid bottom boards were easiest to treat.

Now, here’s an interesting thing: The visible escaping particulate using the ProVap110 was noticeably less than when using pan type vaporizers. I can’t really account for why this is other than the bees don’t have the 2 – 4 minutes to start fanning before the deed is done. I actually used the ProVap110 in the first two hives and thought, “Did it work?” So I loaded the ProVap110, held it downwind, and flipped it to see if it was sublimating the OA. Yes, it was working and it’s done in about 20 seconds. If you look at the video, at the end the guy does exactly this and you can see how thick the plume is and how fast it comes out. Anyway, my point is, there appears to be less particulate escaping the hive than with pan vaporizers – and that’s a good thing!

Cleanup is a breeze. A little water to wash out the areas where the OA comes in contact was quick and easy. The unit itself cools off quickly when unplugged which is good and bad. Good for safety once you are done but moving into different bee yard zones meant having to wait the 2 – 3 minutes for the unit to return to operating temperature. I’m convinced I can shave 30 minutes off my first effort implementing some of the changes mentioned above.

I am satisfied with the unit over the pan type vaporizers for a few reasons: time efficiency, proper sublimation, flexibility in selecting placement of the area the OA is administered, and ease of use. I’d recommend it to anyone that starts to feel that pan-type vaporizing is taking too much of their bee management time that could be better spent more productively.

Addendum August 31st, 2017: After having used the ProVap100 for multiple yard treatments I thought I’d comment on a couple items I hedged on in my first review (above). First, use of multiple extension cords makes no noticeable difference in either warm up time or time to sublimate the oxalic acid. I am now using two fifty foot extensions cords and I get the same excellent performance as with one. Second, After having a problem with my gas powered generator I purchased an inexpensive 400 watt inverter at my local Harbor Freight store for ~ $23.00 USD. Using this as my power source the ProVap100 performed again without any degrading of performance. At $23.00 versus what I paid for the gas powered generator I’d opt for the inverter first unless there was an issue with access to the bee yard. Third, Thus far this year I have not lost my biggest hives post nectar flow and during the Varroa buildup as I have in previous years. I am unable to say that positive outcome is a result of the ProVap100 but I suspect it is a contributing factor. I remain very happy with the unit and from emails and messages I have received from people that have also purchased one they are likewise happy with the efficiency and ease of use of this unit.
