Condensation: Insulating the Vent Box & Dry Sugar

As you might recall from the last post condensation is puddling in Mary. Not certain how or why so I posted the questing at the Beemaster forum (here's the link plus some more good info). What I learned is that condensation is a part of the Winter hive and can be good & bad. It may be necessary since it can be a source of water for the bees. Yet, it can kill the colony if it drips down on the bees. Controlling it seems to bee the task at hand.

• Vent the hive properly so there's not too much. Some type of top vent...(Check)
  
• Tilt the hives to promote drainage away from the bees. Down the sides rather than on the bees...(Check)
  
• Control which surfaces cause condensation by the use of insulation. Such as insulating the top of the Vent Box...(Check, see below)

Mary, sans her T-cover

I'm using 3/4" styrofoam as insulation. This should keep condensation out of the top part of the hive. I left open two vent holes; to the South & East to let the humidity out. I thought about opening the bottom of the SBB a crack but did not. Too easy for a critter to work it's way in and set up shop. The condensation should be less now. I'll monitor of course.

Now this insulated area above the IC provides a good location for Dry sugar to be dumped. As mentioned on the forum dry sugar can help mitigate moisture in the hive by absorbing it. That's good incentive. Plus, Mary's a small colony with half her reserves gone now. I have more honey & pollen frames I'll put in this week but first...

Diner time

I only had a pound of sugar left and gave it all to Mary. I'll pick up a 25# bag tomorrow. The gap between the IC and insulation is 2". I'll see how much sugar I can put in there between refills.

Inspection 1/15/10

Mary
57 F
Sunny

The second fly-day in a row a good time to check the bees. This is my second Winter with bees so one might think it would be easier on me but it's not. I think last Winter I was too inexperienced to know what was happening. Fortunately it was a mild Winter. Yet, this year Winter has been very harsh and I now know just enough to be worried all the time, Ha ha. The girls just spent a month in cluster with daytime temps in the 20's. However, next week's forecast calls for lows in the 30 & highs in the 50's. A warm spell sure would be welcome.

First a quick note about Mary- Weak, under productive, & limping along. SBB (closed), Single Deep, IC, Vent box, & T-cover.

Now back to the inspection. Approach at mid-day, bees flying around the hive. Veil and gloves but no smoker today. Much more evidence of cleansing flights today than yesterday. Good thing I'm wearing the veil. A cloud of bees takes to the air as I remove the T-Cover. A couple hundred bees had congregated inside the vent box above the IC. Yet i still see several bees holding on to one another as if they're still in cluster in the IC opening. Once that comes off i see where the majority of bees are on the top of the frames in the middle of the Deep. Not a great amount of bees, population somewhat low in numbers but I still think they'll make it

For orientation I stand behind my hives and number left to right; more or less. Frames 1 & 2 are still filled with capped honey as are frames 9 & 10. Frames 3 & 8 have capped honey corners and partial pollen filled centers. Frames 4 & 7 are 2/3's empty. Frames 5 & 6 are too busy with bees to check. I replace the frames in this order: 3, 4, 2, 1, 5, 6, 10, 9, 7, & 8. Bees on moved frames were brushed onto 5 & 6 to keep them together. Then it all got put back together. I'll replace the empties with full ones soon. I figure the bees will bee balled up in the middle for now anyway.

Issues.
*Moisture & Condensation. -Again with the puddle of water in the hive. They did this last year too. So over Summer I replaced the solid board with a SBB. I added a Vent cover above the IC with 1.5" holes in it. And all the wooden ware is new. Not much water probably several table spoons worth resting on the luan beneath the SBB (and dripping out the back!) . The T-cover was dry. The IC was dry. As far as I can tell the bees were dry. So why is there water puddling in rows beneath the frames? 8 out of 9 vent holes were closed off so I opened one more, left side, to increase ventilation.

Water leaking out the through the closed SBB ^

Two puddles on the left side beneath the SBB ^

*Heating. Passively that is. -The vent box is 2.5" tall. Heat escapes upwards of course so this box draws heat away from the cluster. To fix this I bought some foam insulation to fill the box. I'll leave enough room, or channels, for the humidity to escape through the vents though.

Vent box currently ^

*Dead bees. -2 kinds of dead bees. The ones that are still standing where they were in the cluster when they croaked. And, of course, the bees that starved head first in a cell. Very few dead in the cells. More dead from the cluster locations.

All dead ^

Starvation ^

Then there's this bee. I believe she wandered away from the ball during a warm spell. Found a whole frame of honey to eat. Then didn't make it back to the cluster before the temperature dropped at night. Poor girl.

I did not get into Myrina as I ran out of time. I'll try to inspect her within the week. Although Myrina almost never has any problems.

First Fly-day of 2010

It's been almost a month since the last fly-day. Compared to last Winter when it happened about every week so I've been concerned. Both hives are brewing with warm bees today. At 55 degrees & sunny it's a great day for flying & the all important Cleansing flights. Tomorrow is to be 56 or so but then it's back to being in the 40's. Tomorrow afternoon I'll peek in each hive to measure their reserves. I have 6 deep frames filled with honey & pollen to replace any empty frames.

Myrina

If you're from the north and need a fix just put on your veil and turn up the volume

-

Mary was the first one out at Noon. Odd I thought since she's the weaker & smaller of the two. It made me nervous about Myrina's condition.

MARY: A good showing

Yet not an hour later out came Myrina to show Mary how it's done. Of course Myrina does have more bees...

MYRINA: Bring out your dead!

We had one not so cold day 2 weeks ago. It was warm enough for the bees to move around some but not fly, 47 degrees. The ground was covered in snow. All the bees did was to toss out the bees that died. The snow was peppered with dead bees in front of the hive. That plus today makes for a big piles of bees. Hopefully the queens will start laying eggs again soon. I have some pollen substitute ready to go. I'll make patties for them. I plan to start some time before the end of the month. Next week might be warmer than this one has been. So hopefully we'll get more days like today.

Winter Storm

Winters here are typically mild. This year, though, is breaking that trend. We got 12 inches of snow dumped on us last night. Normally we wouldn't see that much in a whole season.  Looks like this Winter will be quite a test for my bees & me.

Hives in the Snow

During the storm we had to clear the entrances numerous times.  I don't know how long a hive can survive with a closed off entrance.  I also don't want to find out.  They are calling for freezing rain on Christmas.  I may need an ice scraper before that's all done.

---   ---   ---

The one piece of equipment that helps out the most in challenging weather is the extra wide roofs.  An 1/8 inch sheet of sheet metal extends 6 inches on all sides.  This adds shade in Summer & cover in wet or snowy weather.  The old farmer had them on when I bought the hives.  I never took them off and will include them on all future hives.

Speaking of hives I'm waiting for the next 40 degree day.  A day too cool for the girls to fly but warm enough to allow me to wash the outside of the hives.  Soap & water since I don't like the alcohol & ammonia in window cleaners.

Fly Day

Today was the first day above 50 degrees in weeks.  The bees took advantage of that and broke cluster to get some much needed work done.  Cleansing flights, dead removal, reallocation of reserves to name a few.  The bees in Mary, only 1 box, were massed in the SE corner working the end frames.  Myrina's girls were also in the SE corner but mostly in the lower box, again working the end frames.

I really only went in because i needed to take the Apistan out.  The target date is Friday the 18th but it is forecasted to be freezing again by then. I also looked around Myrina some pulling the frames from the upper box.  All honey and as usual angry bees.  I saw no problems.

This time next month I hope to be feeding both hives with pollen.  I want to build up the population as best i can for the Spring splits I'm planning.

Screened Bottom Board & Winter

I have a Dadant SBB on Mary.  It comes without a bottom sheet normally used for Varroa counts.  I can close it of with anything made of plastic or wood but I thought I might leave it open all Winter.  Moisture has been a problem with this hive so I want to vent it as much as possible.  Last year saw a puddle of cold water drip down through the hive during Winter.  I did not want to repeat that again. But, it has been a very cold couple of weeks & it looks like it will be a sever Winter.  The bees have been in cluster for almost two weeks now.  Last Winter we had fly days every week or so.  I took a picture from under the SBB of Mary yesterday and found a bunch of dead bees.  That is natural, i think, but concerning.  Since she is down to a single deep her cluster is very close to the bottom edge.

Dead Bees 

I sealed off the SBB this evening after work with a piece of luan.  I'll leave it there for the rest of Winter.  The Vent box is still on the hive so the humidity will continue to dissipate from there.  I have designed a SBB of my own that utilizes a deep tray beneath the screen and some adjustable side vents.  I'll post it when its made, after the New Year.  

Some beeks leave their SBB's open all year some beeks use only solid boards.  I guess I'll be taking the middle road on this issue.  SBB's all year but closed off during Winter.  The timing will be dependent on the weather.  But, I figure the hives will be closed off from December to April.

Myrina still having the Solid BB was left alone.  Both colonies showed signs of activity inside the hives.  As good as she is about her solid board I don't yet know if she'll get a SBB.

Wax Moth & Mary

At 60+ degrees today I went into both hives to remove the HTF's. Lots of crystallized syrup. I broke it up on to a cookie sheet & left it for the bees. However, in Mary I found 4 frames infected with Wax moth. 2 frames in the top box & the 2 adjacent frames in the bottom box. The frames had pollen & some uncapped honey. The frames had to go into the freezer; which would leave a substantial hole in the hive. So I broke Mary down to a 1 brood box hive. All I had left to do was pick the 6 additional frames to remove. I left Mary with 5 honey frames, 2 pollen frames, & 3 brood frames. She has a smaller population so the 1 deep should be better. It may be that she had too small a population for the 2 deeps leading to the wax moth problem anyway. When I checked her 4 weeks ago I saw NO Wax moth. I thought After a few freezes I wouldn't need to worry about Wax moth any more. Oh well...

Myrina looked fine with a good population and plenty of reserves. I also closed off 6 of the 9 holes in each of the vent covers on both hives. 3 holes should be enough to vent the humid bee breath. I'll monitor for condensation throughout winter.

A Quick Look

A cool 48 degrees & sunny today. An OK fly day for the bees. I went down to the hives to check activity. I closed off the entrance. Then waited to see what the foragers were bringing in.

Mary's girls were bringing back some wax from that old frame I left out. No pollen. Plus I checked under her SBB and still see signs of CB. I will lay a stone pad beneath the hives this winter to reduce ambient moisture near the hives next year.

Mary's girls coming home almost empty handed

Myrina's bees, of course, were returning from somewhere with some bright orange pollen. I have no idea whats blooming but something is. Even our mums are gone. I'll guess at somebody's potted flowers and leave it at that.

I count 6 with pollen

--- --- ---

Also I took their Fall pictures:

Mary ↓

--  --

And Myrina ↓

Both have double deeps, HTF, Inner cover, Vent box, T-cover, & a tin top sheet. Mary has her SBB while Myrina has a Solid BB. Myrina will get her SBB as soon as I make it. Winter will see even more reduction.

--- --- ---

The November meeting was last night. We hosted a panel of 3 experts to pose questions to. Two local guys and one man from N.C, a Bob Cole. Mr. Cole made the point that we should be raising our own Queens. That plus what else I've read convinces me to do just that. I'll need to read much on the topic this Winter to make a successful try at it.

That and 2 splits will make for a very interesting year in 2010.

Honey Harvest 2009

No I'm not joking. Earlier this year i set out a Swarm trap; Nuc, pheromone, & one capped honey Deep frame. I had placed one extra honey frame in the freezer in case I needed it. And there it stayed. The Wife found it tonight while cleaning out the freezer. A whole deep frame of capped honey. That's it. My entire honey harvest for 2009.

Well I don't believe this requires an extractor (Ha ha) so I used the Mash method. I've not done this before so it would be an experiment. Cut the comb into a pan and mash to a pulp. Pour into strainer and place on top of large saucepan. For a handful of frames I would prefer this method to spinning. Much less equipment.

So now the honey mash sits draining into a pot. Tomorrow I'll jar it. Should be 2 lbs. worth. Plus I have another wad of wax. Which will be added to the bur comb wad and processed. There might be several ounces of the stuff now. Cool.

A little honey & a little wax

Now let me look a gift horse in the mouth. The honey is what I call brood honey. Coming from a brood frame the honey gets made in cells used for brood rearing. To me it gains a distinct off flavor being in the presence of cocoons and what-not. However, we will definitely use it. Most likely in cooking than in tea.

I suppose I could use it on the bees. I don't remember which hive it came from but neither hive had AFB or EFB this year or last.

Wax vs. Green Mold

I've have trouble with a Green mold that keeps appearing in Mary. It beat up some honey supers last year (click here to see) and recently go into my new T-cover this year. I always assumed it was a moisture problem. I did everything I could to vent the hive and still the mold came back.

I posted the problem in the on-line Bee Master forum. Many good responses also dealing with moisture. Then finally one beek mentioned that new wooden ware may sprout mold if the bees have not properly sealed the surface with propolis/wax.

BOOM! There it was!

When I thought about it all the wooden ware that came down with the mold was new. So I need to make sure all the wood is treated by the bees or someone else. Like me.

The current victim is the telescoping cover on Mary. It's a year old but the bees never waxed it. So I took it upon myself to wax it.

Notice that you can see the inner outline of the hive

First I washed off the mold with bleach then dried it. Then warmed up the wood underside under a lamp. While that was happening I melted some bees wax & got a metal scraper. When all was ready I removed the lamp and poured the wax onto the T-cover. To keep the wax soft as I spread it I used a blow-drier. I did not coat to the edge of the T-cover. I feel that exposed wax may attract Wax Moths. After a good coating I put the T-cover back under the lamp to help the wax melt in. When completed the T-cover went back out on the hive.

Wax soaking into the wood

I remembered Michael Bush's article on how he wax dips his hives. So I got the idea to hot wax the inside of my previously painted equipment. If this works (no more mold & no added pests like Wax Moth) I'll be sure to do this in the future when the bees don't do it themselves. I imagine that a strong & healthy hive will have no problem with this task. Mary on the other hand has always limped a little.
