2015-10-25: Winter Prep

We've finally hit a few nights of freezing temps so that means it is time to complete any winter prep that needs to be done on the hives.  I have empty feeder jars that need to be removed, boxes with no stores in them that need to be taken off (the bees don't need a bunch of extra space that serves no purpose) and mouse guards to be placed on.  I also need to decide what to do with my newly established nuc hives.

Old Nucs - Yellow/Green hives:

These are the splits I made some time ago that were moved into full sized boxes last month.  They've been feed 2 quarts of syrup each in the hopes that they would draw the empty frames with wax and start filling them up.  If I found 10 good frames then I was thinking to take two nuc bodies (5 frames each) and stack them.  It is suppose to be easier for the bees to move up in the winter and it would be easier for the bees to cover 5 frames at a time instead of 10.

Yellow Nuc:

I had suspicions during the last inspection that I had waited too long to transfer this nuc to a full sized hive and they decided to swarm (I saw some torn open queen cells).  The bees seemed "flighty" and the only brood I saw were drones.  The number of drones walking around the frames was high, especially since they should all be kicked out of the hive by now!  I did spot some eggs and developing larva but something was telling me that this was not right. 

Drones, lava and eggs but no queen

So, either I have the start of laying workers or I have a queen laying all drones.  On top of that, the bees had not touched a single new frame that I had placed into the hive.  Stay tuned for more on the Yellow Nuc during my inspection of the Green Nuc....

Green Nuc:

I was a bit annoyed after pulling the first few frames since the bees had not touched them at all.  Thankfully the original 5 frames that were moved into the hive looked pretty good.  Lots of capped honey and worker brood!  Two more frames in and I spotted the queen with her pretty green dot. 

Queen with a pretty green dot

I was even nicely surprised that after I moved past these 5 frames the bees were actually drawing out one of the new frames! 

Drawing out a frame with new wax

Have I mentioned how I love festooning bees before?  =) 

Festooning bees

 Based on my findings between both nucs, I decided the one was probably queenless and had the start of laying workers and the other was queen right.  I thought it would be a good idea to take two 5 frame nuc boxes and stack them with the best frames from each hive.  I unscrewed the bottom from one of the nuc boxes and stacked it on top of another nuc box.  Crap!  They are not made to stack.  There was a large gap between the two that would be open to the air.  Ugh.  I guess I need to deal with the full sized boxes instead.  I decided to do a newspaper combine and thankfully I had one sheet of newspaper left!  I placed it across the top of Green nuc, picked up the Yellow nuc off of its bottom board and placed it on top of the Green nuc.  The bees will eventually chew through the paper and this slow integration will hopefully prevent any fighting between the bees before they merge together into one happy family.  I'm just hoping that there wasn't some drone laying queen that I didn't spot in the Yellow nuc that ends up battling with Green nuc's queen.

Newspaper combine complete

Where did that orange pollen come from?

Yellow Hive:

This is my cutout hive that has made some really good progress over the summer.  I removed the empty feeder jar and took a look through the top box.  The bees were covering about 6 frames and had most of them drawn out. 

Yellow Hive bees

Quite a few were filled with capped honey.  Looking down into the box below I saw lots of bees and some rubber bands still on the frames from the cutout!!  They typically chew through them and dispose of them but I'm guessing they've propolised them right onto the frames now.  I'll have to remove them during the first inspection in the Spring.

Green Hive:

The top honey super on this hive was filled with drawn combs that were completely empty.  I thought for sure that when I added them that the bees would fill them quickly with the Goldenrod flow.  No such luck.  I pulled this box off after clearing a few stray bees off the frames.  I pulled a few frames from the next honey super and at least there was some capped honey there.  Looks like that box will stay on for the Winter.

White Hive:

Looking at the top honey super on this hive I could see that it was packed.  I knew this from my last inspection but I had also seen a large pile of dead bees in front of the hive.  I was concerned that this hive had been robbed out by other bees.  Well not a single frame of honey appeared to be touched so this hive should have some great stores going into Winter.  It also had a nice population of bees and when I looked closely at the pile of dead bees I saw numerous dead yellow jackets in the pile.  Maybe they tried to raid the hive and picked the wrong one to screw with!

Battle aftermath

To complete my tasks I needed to put the mite sampling boards back into the hives that had screened bottoms to prevent any wind drafts blowing up from the bottom of the hives.  With that done I also wanted to put my mouse guards on but with the entrance reducers on it didn't really look like they would fit properly.  Based on http://www.honeybeesuite.com/what-size-hardware-cloth-is-best-for-beehives/ it looks like #4 hardware cloth is the proper size for a mouse guard.  So I think I'll grab some and use that instead.

I'm also considering getting or building some candy boards that come with a top entrance.  This would allow the bees to leave the hive for a cleansing flight during the Winter if the bottom entrance happened to be plugged up with dead bees.

With four hives going into Winter and some diversified genetics (one Italian, one cutout wild open mated and two "northern" queens), I'm hoping to have some better luck overwintering this year.  Wish for a mild Winter and wish the girls luck!

Until next time, thanks for reading!

Winer Prep: 2014-11-28

I'm trying a few new things to prepare the hive for Winter this year.  Ideally I would have two hives of similar strength and try something new on one hive and not the other.  Then I could compare the results in the Spring and see if it made any difference.  Not exactly a complete scientific study, but it would be a start.  Alas, I only have the combined Green/White hive to overwinter this year, so it is all or nothing. 

The first thing I am trying is adding wood shavings to the ventilation board on top of the hive. 

Vent board.  Notice the propolis on the edges and center of the screen

During the Winter, the bees generate heat to keep the cluster warm.  That warm, moist air rises in the hive and when it hits the inner cover can possible condense.  This water can eventually build up and drip back down on the bees.  Not good.  Bees don't have too much trouble handling the cold.  But if they are cold AND wet, it is a death sentence.  So, the idea is that the warm moist air rises up through the hole in the inner cover and then through the wood shavings in the ventilation board.  If it does condense at all, the wood shavings absorb the moisture and it cannot drip back down on the bees.  I think the loose wood shavings also allow for some air circulation from the bottom of the hive without creating some sort of wind tunnel.

Wood shavings added

The second thing I am trying is using a Winter wrap on the hive. 

I put velcro on the wraps to attach them

In the past I used a wind break to keep most of the wind chill off the hives.  They were big, bulky and heavy sheets of plywood that I would stake into the ground.  I would then have to put braces on them so they wouldn't blow over.  Way too much of a pain.  My thought on the Winter wrap is that it would serve the same purpose as a wind break and be much easier to use and store.  From all that I have read, the opinions really go back and forth on the benefit of using them.  They do help to block the wind for sure but they also may block the solar radiation on a nice sunny day from warming the hive.  Even though they are made of black plastic that would absorb some sun, there is a very thin layer of foam on the back side of the plastic.  I think that would prevent the warmth from actually reaching the hive.  Any heat transfer experts out there that can weigh in on this?  I know of others who staple black tar paper directly to their hives.  That may actually allow the heat to transfer into the hive enough for the bees to move around and get to other sources of honey.  I really wish I had my Arduino hive monitor running so I could see the temp difference from outside and inside the hive on a sunny day!  Maybe next year.

All tucked in for Winter

The last thing I did (which is no different than previous years) is to take the entrance reducer off and put the mouse guard on.

I have also gone out to the hive about once a week and used my J-Hook style hive tool to scoop out the dead bees from the bottom of the hive. 

Bring out yer dead!  (And look out for the 1 attack bee)

You don't want so many dead bees to build up on the bottom that they can no longer get out of the hive.  What has really amazed me is that I am still seeing drones!!  I really thought that every last drone would have been expelled from the hive two months ago!

So far, December has been mild.  Cold, but not horrible.  The end of this week is suppose to reach 40 degrees F.  I'll take it!  All I can really hope for is that this Winter isn't as bad as last Winter.  Waiting is the hardest part  =)

Until next time, thanks for reading!

Guest Beekeeper : 2014-06-25

One of the fun things about beekeeping for me is teaching others about bees.  I have found many seemingly willing students.  Or at least ones that feign interest while I blab on and on about the bees.  I have also tried to get as many of these people as possible into the beehives.  For this inspection, I was fortunate enough to have Byron be my guest beekeeper.  It sure doesn't hurt to have an extra set of hands either!

My main concern for this inspection was to make sure the bees hadn't run out of room, since each hive consisted of only one box.  At this point they should be covering most of the frames and be ready for a second box to be added.  I was also hoping I hadn't waited too long and they weren't preparing to swarm!

Green Hive:

I took my time going through this hive since I wanted to be able to show Byron all the facets of beekeeping.  How to separate and manipulate the frames.  How to use the smoker and hive tool.  And what to look for in the hive: nectar, pollen, honey, eggs, larvae, capped cells, workers, drones and the queen.  The bees had just started to draw wax on the first two frames in the hive so I was able to show him how they create the wax in an empty frame.  He was also able to see the festooning behavior of the bees as they constructed the new wax comb.  The queen in this hive remained elusive and we did not spot her.  Although we did see some eggs and very young lava so she was there somewhere.  A second deep box of empty frames is now on this hive.  I have a feeling I should have used a technique called pyramiding to encourage them to move into the new box.  If they haven't done so by the next inspection I will make it so.

White Hive:

This hive had a second box added with some frames from the hive that died this past winter.  Some were empty brood frames and some were filled with honey.  Since this hive appears stronger, the bees were already working these frames.  After going through these I let Byron take over the inspection.  I'm sure it was his observation of my fantastic abilities that allowed him to jump right in like a pro!!  LOL

Byron inspecting the hive

The queen in this hive seems incredible to me.  She has solid brood patters across almost every single frame.  This hive will sure need the room in that second box!

Lots of brood

Even more brood

I never get tired of seeing new bees being born and emerging from their cells.  This inspection was no disappointment when we spotted 3 drones being born at the same time!

Welcome to the hive boys

After Byron had pulled 8 frames I thought for sure I was going to strikeout in showing him the queen.  But when we pulled frame 9 there she was!

Smile Queeny!

After watching her run around for a bit, we completed the inspection and closed up the box.

All in all, both hives are doing well and it was a great evening for an inspection.  Next inspection I will hopefully see that the queens have moved up into the second box and started laying eggs there.  I'm also planning on creating one or two nucleus hives and buying a "northern" queens to put in them.  At worst, this will allow me to have some backup hives in case one of the hives fails.  At best they will become fully established hives with better genetics for surviving these horrible Michigan winters!

Until next time, thanks for reading!

Second Inspection: 2014-06-10

I was very eager to complete this second inspection for a few reasons.  First, I was very eager to retrieve my fist set of Arduino Smart Hive data!  Second, the hives are currently at Installation +30 days (Bee Math) and there should be many more young bees in the hive.  Not only will these bees be nurses for the next generation, but they will also be wax comb builders (Honey Bee Worker Jobs).  So, they should be expanding the nest area and allowing more bees to forage for nectar and pollen.  The increasing number of bees also means they will be running out of space soon.  Normally in nature, the size of the cavity the bees live in does not increase and when they run out of room they swarm.  Part of being a beekeeper is controlling the bee's swarming nature by adding more space (boxes) and I needed to see if it was time to add another box or not.  If your hive does swarm you've lost probably half of your bees and your old queen.  Not a good thing if you actually want any honey.  Plus most of your neighbors probably wouldn't appreciate a swarm of bees landing in their yard!  Well, onto the inspections...

Green Hive:

I opened the lid and found that my ventilation board with my electronics in it was nicely stuck to the top of the lid.  There must have been some propolis left on the underside of the lid and it works really nicely as glue.  I spent a few minutes trying to remove the ventilation form and when I finally removed it, I notice a LARGE, furry black spider resting comfortably on the underside of the lid.  Thankfully I was armed with a steel hive tool and dispatched the menace quickly.  I really dislike spiders but I also know they do eat "bad" insects, so I try to leave them alone when I spot them in the garden.  But when they are around my bees I show now mercy!  I'm sure beekeepers in Arizona, Florida or Australia can get some really nasty surprises around their hives.  Yikes. 

Anyway, after all that drama, I pulled the SD memory card from the Arduino and downloaded the data.  My first disappointment was that it appeared that it only logged about 3 days worth of data.  It appears my 6 AA battery pack didn't last very long at all.  I'll be looking into an alternate power source for sure now.

Arduino Smart Hive data

With that said, it was cool to see that the general data collection does work!  From the data it looks like the external sensor might be a little flaky since the humidity spiked at 100% a number of times and the temperature measured at 103.82 F on June 2, 3:22 PM.  According to the weather report on that day, the highest it hit was 82 F.  Other than that oddity, the data looks consistent.  What I really like seeing are the readings from the brood area.  The temperature reading is a very flat, steady line, right around 95 F.  Despite what the outside temperature is, they do a fantastic job of maintaining the same temperature and humidity levels where the baby bees are being raised.

Pulling the first two frames from the hive, I saw they were still empty.  The third frame in was built much wider because of the empty space next to it.  With the top down view in the photo below, you can see how the wax sticks out past the top bar of frame 3.

Green Hive

Frame 3 was heavy with honey and frame 4 was the first to have brood on it.  Typically the brood nest is toward the middle of the hive so it was no surprise to see frame 5 had a lot of brood on it.  The other side of this frame had a large empty area where all the baby bees had already hatched out of their cells.

Hatched Brood

Frame 6 looked very similar to 5.  Frame 7 was about 50% covered with capped brood and had a large section of new wax drawn out.  Looking closely I could see there were eggs in almost every cell in the new section of wax.

Frame 7

Frame 8 and 9 actually had some large patches of brood on them with an empty queen cup as well.

Queen Cup

Thankfully there wasn't anything in the cup so it doesn't look like they are preparing to swarm or replace the queen.  The last frame hadn't really been touched by the bees since the last inspection.  So in total there are still 3 empty frames in Green Hive.  Looks like I'll be ready to add another box during my next inspection.  They are coming along nicely!

White Hive:

The first thing I noticed after removing the inner cover of White Hive was that I could see bees looking up from between almost every frame!  This hive in increasing in numbers more quickly than Green Hive for sure.

Looking into White Hive

The bees had stored quite a bit of nectar and pollen and the brood nest started a few frames in.  The queen in this hive knows how to lay some eggs!  Look at the photo below.  This frame is wall to wall brood with very few empty cells.  They will be bursting at the seems very soon.  I will need to add a second box for sure next week!

Lots of future bees

You can also see the patch of drone brood that was built along the bottom of this frame.  And speaking of drones, I was able to witness one being born.  Very cool!  You can watch the 30 second video here: http://youtu.be/X1rwGvIbuck

The last thing I did before concluding the inspection, was to change the entrance reducers on both hives from the small opening to the medium sized opening.  The population should be steadily increasing now on both hives so they should have no trouble defending a larger entrance.  This will also help alleviate any congestion as the foragers come and go all day long.

Looks like I have a lot to prepare for the next inspection.  New boxes to add and hopefully another way to power my Arduino.  So, until then thanks for reading!

You Take the Good, You Take the Bad: 2013-04-30

We have had really nice weather here in Michigan for about the last week.  It was a long time in coming but it is finally here.  So, of course, I was eager to get into the hive(s) and see what the girls are up to.  I had a few tasks left over from winter that I needed to attend to as well.  First off, removing and cleaning up my dead hive, Green Hive.  I began to disassemble Green Hive and quickly noted that the bees from White Hive were greedily robbing out all the remaining honey left over in Green Hive!  It didn't take them long to find an undefended honey source!  I pried each box apart and hauled them away from the bee yard.  I then applied a liberal amount of smoke to each box to try and drive the remaining bees out.  Finally, the last box was removed and only the bottom board remained with the deceased remnants of Green Hive gathered in a sad pile.

I scanned through the dead bees to see if I could find the queen and I did not see her.  I plan on going through all the frames from each box and decide if I will melt down the wax or keep them for later use.  Hopefully I will find what was left of the winter cluster somewhere in there.

The second task I needed to complete was the remove the extra sugar I had placed in White Hive as emergency winter feed.  I'm not sure they really ate much of it.  Anyway, I removed it and put some empty frames back in.  Now onto the inspection!

Typically the bees will start in the bottom boxes during the beginning of winter and gradually move up through the hive over the course of the winter, eating honey as they go.  So, come the spring, you expect to find them at the top of your hive and that is where they were.  I pulled the first frame and BAM, there was the queen!  I'd like to think my queen spotting abilities have improved but this time was way too easy.  She just visually jumped right out to me.  I could see that she was doing her job as the frame was fairly well covered in sealed brood, eggs and larvae.  The workers have also packed quite a lot of pollen along the top of this frame as well.

Brood Frame

I zoomed in a bit with the camera once I saw the larvae because I usually cannot spot eggs unless I'm looking at a photo.  The eggs are about the size of a grain of rice, so I don't think my vision is that bad yet.  Can you see the larvae of various ages tucked in their cells?  They look like little 'C' shaped grubs.

Larvae

Here is a slightly closer look with a lot of pollen packed in near the off to the lower right in the photo.  Pollen is very important in raising new bees so they keep it stored close!

Larvae with pollen

As I continued my inspection, I became concerned when I saw brown spots along the top and sides of some of the frames.  These brown spots are also referred to as bee poo  =)  Normally bees are very sanitary and never "go" inside the hive.  If they go inside the hive it can be the sign of a disease called "Nosema".  It is a spore that infects the gut of a bee and causes intestinal problems.  I've also read that it could be simply "bee dysentery" and could easily clear up on its own.  I will have to closely monitor this in the future.  I may decide to swap out some of these frames once all the brood has hatched out of them.

Nosema or bee dysentery?

 During an inspection you check for a few things:  Queen?  Check!  Eggs?  Check!  Open and Closed Brood?  Check!  Pollen?  Check!  Honey?  Check!  Things are looking pretty good.  The last thing I'm looking for are drones.  Spring time is also swarm time and usually the first drones are emerging at the same time.  I'm also planning on splitting this hive and you need drones in the air to mate with a new queen.  I did not spot any drones nor did I see any drone brood, so it looks like they might be a few weeks away yet.  I saw the first dandelion in the yard so I think a nectar flow is coming soon!

All in all I guess you take the good (they survived the winter) and you take the bad (maybe have Nosema), you take 'em both and there you have the facts of life.  Sorry.  Really bad but I couldn't resist!

Until next time, thanks for reading.

First Hive Inspection: 05-08-2012

Weather Report:
High 60's, mostly cloudy and breezy

Finally the weather has cooperated and we were able to do our first inspection.  I swear every time I saw a decent weather forecast and planned on the inspection, the weather would turn to crap hours before!  Grrrrr.

So, why do an inspection anyway?  Well, we are looking for the general health and well being of the colony.  We want to see that the bees are gathering food (nectar and pollen).  We also want to see if they are raising baby bees (eggs, uncapped and capped larva).  The typical stages of a worker bee can be expressed by this simple formula (start at three and double the number): 3 + 6 + 12.  Three days as an egg, six days as a larva (the cell is capped over at nine days) and twelve days as a pupa before the baby bee emerges.  A total of twenty one days from the day the egg is laid until the new bee come out.  We are also checking for any pests, diseases or other problems that may arise.  What did we find?

Inspection Report:
White Hive:
After lighting the smoker and blowing a few puffs of smoke into the front entrance, I cracked open the lid and found that the feeder jar was empty.  I brought the little remaining sugar syrup that I had left and filled it about half way.  Time to make up some more syrup!  I removed the top box holding the feeder jar and blew some more smoke into the hole in the inner cover.  After waiting for a bit for the smoke to take effect, I removed the inner cover which the bees had lightly glued down.  It was a bit sticky but I was able to lift it without using the hive tool to pry it off.  What I found was a bunch of burr comb hanging down!

Looks like they have been busy!  Don't they know they aren't suppose to build comb like that?  =)  Basically bees work within "bee space" or about 3/8 of an inch.  It was discovered that when given more space than 3/8" the bees will fill it with wax comb.  If given less space than 3/8" they will fill in the gap with "bee glue" or otherwise called propolis.  For more information about this interesting phenomenon: http://en.wikipedia.org/wiki/Langstroth_hive

After scraping this offending comb off of the inner cover, I started pulling the frames and taking a look.  The first five frames were mostly empty with only a few bees hanging out there.

On frame number six I found some stored pollen and nectar!  The nectar looks like glossy pools of water in the cells.  The cells filled with yellow and orange are pollen from different types of flowers.  Very cool!  It is interesting to see how they have outlined the rim of the plastic cells with a small bead of light yellow wax comb.  I am very happy to see this because I have read that sometimes bees will have trouble accepting fully drawn out plastic frames like this.  Glad to see that will not be a problem!

Frame number seven seemed to be more of the same but I'd really like to see some evidence that the queen has started laying eggs.  Frame number eight is looking the same too isn't it?

Can you spot the different kinds of bees in this close up photo?  There are three different kinds of bees.  The queen who lays all the eggs in the hive.  The workers who are all female and make up 90% or more of the total bees in the hive.  And finally the male bees, the drones.  I describe them as unemployed guys who sit on the couch all day drinking beer, yelling at the girls to bring him a sandwich and checking out the hot chicks all day long!  =)  The drones do no work, the female worker bees feed and clean them and the drone serves one purpose.......to mate with a virgin queen.  If the drone is successful, he dies as his insides are ripped out (I'm being polite when I say "insides").  If a drone fails to mate, and survives into the fall, he is eventually kicked out of the hive by his sisters to starve, freeze to death or get eaten by another critter.  Bummer.

On to frame nine....finally there they are!  Larva in the cells!  They look like shiny little grubs shaped like the letter "C" right in the middle of the frame.  I also see what might be drone brood.  Since a drone is physically larger than a worker bee, the cell that they are raised in has an enlarged, dome shaped cap on it that protrudes from the frame.  Because of this they are sometimes called "bullet brood".  Spot any drones yet?  The key is the eyes.  Since the drone depends on his eyesight to spot a flying queen, his eyes cover almost his entire head.

Finally, frame number ten.  Wow, they sure built some weird looking comb on this frame.  A large section of comb protruding with tunnels underneath it!  After looking at this frame and the one next to it, I can see that this frame is warped away from the neighboring frame causing extra space there.  And bees fill extra space with comb!  I might have thought about removing this comb but I see lots of eggs in it and I really don't want to loose all those baby bees.  They really have everything in this weird comb!  Brightly colored pollen, glistening nectar, larva, capped larva (pupa) and if you really zoom in,

you can see tiny things that look like grains of rice.  Those are eggs the queen has laid.  Since we know that an egg changes after three days into a larva, we know that the queen was at this spot sometime in the last few days.  It would be nice to spot the queen, but this is the next best thing.  I'm wondering if the bees were in the process of capping a few of those cells of larva, or if I somehow tore them open by accident.  The edges of the cells look a bit ragged and I'm not quite experienced enough to be able to distinguish some of these subtle differences.

I find it really beautiful all the many different colors of pollen they have stored on the left hand side of this frame.  Orange, yellow and almost a white color.  Which flowers are providing all this color?!

Green Hive:
Sadly the camera battery died just as we were closing up the white hive, so have no pictures of the inspection on green hive!  =(  The top feeder was empty when I opened it up but I counted almost thirty dead (drowned) bees in the feeder and mold had started to grown on the floats.  I am not happy with this feeder.  I decided it is coming off and I will replace it with an inverted jar feeder just like on the white hive.  The inverted jar is much easier to maintain and doesn't drown any bees.  I have the foundationless frames on this hive and the bees had comb drawn on four of the ten frames.  About 3/4, 1/2, 1/2, and 1/4 of those four frames were filled with comb.  I found it very difficult to see what was in the cells of those frames.  I did spot lots of nectar but there were so many bees covering the comb that I couldn't tell for sure if I saw capped honey or capped brood.  How do you other beekeepers get your bees to move out of the way so you can see this stuff?  Do you brush them off or use your fingers to move them aside?

All in all I was very happy to see that the bees were drawing out comb, storing pollen and nectar and making more bees!  I would have liked to have spotted the queens but I was happy spotting eggs in the white hive.  I'm hoping that in my next inspection that I will have a better technique and a camera with a fully charged battery!

Until next time, thanks for reading.
