A Long Overdue Update from the BeesofSpike Apiary


The BeesofSpike are back online.

LandofSpike would like to offer his sincere apologies for his absence from the blogosphere over the last few weeks and for the lack of news from the BeesofSpike. 

This isn't due to a lack of action in the Apiary nor is it due to any Bee-related disasters. In fact, the BeesofSpike are now in the best of health, the colony has expanded excellently and the bees are currently storing up plenty of provisions in readiness for the winter.

LandofSpike's work in the Apiary has continued unabated but he has unfortunately been unable to devote any time to the blog due mainly to the demands of the BeeKeeperJuniors' summer holidays and a sizeable workload in the pesky WorldofReality.

Fortunately he has taken meticulous BeeNotes and will, in time, be able to transcribe all the action to the Land of Bees blog. 
He has also, whenever possible, photographed the important elements of his inspections, his day-to-day observations and any other bee-related activity. 


It was good to see new comb appearing on the new frames

In addition, he and the ever present BKJ1, have recorded every inspection with the trusty CamcorderofSpike.

So, with the excuses out of the way, LandofSpike can now reveal that, since our last post, the bees have been doing just fine.

There she is... the important looking one in the middle

Once the good weather kicked in on July 20th and once the mite situation was under control the colony started to thrive. 
The bees eventually moved into top gear for the end of the summer.

The new comb and stores of honey have been appearing at an ever increasing pace and the new Super has filled extremely quickly.
LandofSpike has decided to leave his Bees with the Super in place for the winter. The focus for this year is to get the colony through the winter and leaving them with a big box of full and heavy frames of capped honey seems to be an obvious choice.



Honey production up and running

They are currently harvesting the final pollen of the year.
Close to the Apiary, the grounds of Spike Towers are home to large swathes of ivy so the workers are stocking up while they can.

I counted them all out and I counted them all back




The BeesofSpike have developed a seasonal taste for syrup and they are consequently taking down industrial amounts of 2:1 sugar solution from the top feeder.
Their concerted effort at draining it dry started in the first week of September and they've been at it ever since.

LandofSpike has today returned from the local supermarket with his sixth 5 kilo pack of cane sugar of the Autumn. 
He has made up yet another batch of syrup and is just waiting for it to cool before refilling the feeder in the morning.
Details of their syrup consumption will be dealt with in a separate post and will also include the methodology for preparing the feed.


A familiar sight in the LandofSpike kitchens over the past month




The varroa count is down to about 1 per day, which means that the Apiguard has done its job perfectly. The All Clear has been sounded and the colony should be able to overwinter without fear of mite attack.
There is consequently now no sign of DWV (deformed wing virus) which, whilst the varroa had hold, had afflicted some BeesofSpike workers.

The Drones have all now been booted out. 
This took place around the end of August and the start of September.
Watching workers escorting drones to the edge of the landing board then encouraging them, nightclub bouncer style, to take off into the blue, was fascinating. 
You could almost see the workers dusting off their hands as they swaggered back to the hive, job done.


No way back for the Drones



LandofSpike's smoker technique has also improved.
From a shaky, hit and miss start, he has developed a sure fire, works-every-time method. There will shortly be a smoker-dedicated post revealing his methods to a waiting world.


Foolproof smoker lighting technique soon to be revealed!


Right, that's all for now.
It's been a rather sketchy, and not particularly cohesive, précis of the recent activity in the Apiary but hopefully it gets us up to speed on the current situation.
There is an awful lot more BeesofSpike info to upload in the near future so LandofSpike is going to try and sort it into bite-size chunks.
The next post will be along very shortly.

The Empire Strikes Back... Apiguard vs Varroa



The previous episode of BeesofSpike ended with a pretty sorry colony of bees blighted by a rather nasty infestation of the varroa destructor parasite.

A new BeesofSpike worker afflicted with varroa

Varroa can very quickly destroy a colony so LandofSpike needed to start medicating his bees straight away.
The batch of Apiguard that he had ordered online was not due to arrive till the next week, which would be too late.
However, one emergency trip to the not-so-local Bee Supplies Shop across town later, and this was no longer a problem. 

So before he set to work dosing the hive with his newly purchased bee medicine, there was just time to find out about Apiguard.
What is it and what does it do?

Varroa Destructor does not like this

Apiguard is a shallow tray of thymol in a slow-release gel which is placed in the hive.
It's the thymol which is the active ingredient. 
It kills the varroa mites.
A treatment period runs for 6 weeks and uses 2 trays of the stuff.
The first tray is left in for 2 weeks. 
It is then replaced with a second tray which is left in for a further 2-4 weeks.

The bees themselves distribute the thymol around the hive. They see it as something which should be removed and whilst the house cleaning workers are busying themselves cleaning it away their activities distribute it to every part of the hive, and therefore to every varroa mite.

The distribution happens more efficiently in warmer temperatures as the thymol sublimes more quickly and is easier for the workers to detect.
The varroa particularly dislike the thymol vapour.

Varroa, at the moment, has no resistance to thymol.
Some strains of varroa have already developed resistance to some pyrethroid varroa treatments but the non-specific effects of thymol on the varroa mean that it's likely to continue to be an effective deterrent for the foreseeable.

Currently, Thymol is LandofSpike's favourite chemical


Before the treatment, LandofSpike removed, cleaned, oiled and replaced the varroa board.
the varroa count was 67 individual mites across the whole board which amounts to 33.5 per day over the two day period.
This is way too many.

Waaaaay too many varroa


Inserting the Apiguard was pretty simple.
LandofSpike and BKJ1 suited up, fired up the smoker (not particularly brilliantly this time, must work on our technique) and smoked the entrance.
The roof and top feeder were removed and the brood box smoked.

BKJ1 tests his smoker

There was time for a quick inspection to reveal that, although still small and beleaguered by rain and varroa, the colony was making new honey and pollen stores. Also, the queen, although not spotted this time, was laying new brood.




The Apiguard pack was opened so that all but one corner of the foil was removed and the lid was folded back. The open tray was then laid on top of frames 4, 5 & 6, above the most active part of colony.

Opened Apiguard tray laid on top of broodbox frames


A super was placed on top of the brood box with the corresponding super frames removed to make space for the Apiguard tray.


The queen excluder was left out out for the time being.
The reasons for this were:
a) to give the bees clear access to the Apiguard tray, the QE may have acted as a barrier.
b) to give the bees unchecked access to the top feeder if they needed to use it.
c) it was decided that there would be little risk of the queen starting to lay in the super frames as there was as yet no comb on them, just foundation.


The entrance reducer was fitted partly to stop too much of the thymol vapour escaping that way and also simply because our small colony didn't really need that big a front door in this grim weather.

I'm sure this door used to be bigger...

The base of the hive should really be shut during treatment to trap the thymol vapour inside but that isn't an easy option with the EPS hive so, with the varroa mesh screwed in place, the varroa board approximates a partial seal.

With the thymol installed, the roof and top feeder were replaced on top of the new super and the hive secured with its strap.
Mission accomplished.






As a little schoolroom addendum to our in-the-field account, here's a little extra theory.

Instead of using a super to make space for the Apiguard, LandofSpike could have used an eke.
An eke is simply a shallow, and hollow, 4 sided box, the same dimensions as the hive, which fits above the brood box and acts as a spacer so that the tray of Apiguard can sit on top of the frames in the newly formed space between the frame tops and the queen excluder or the super.
Without an eke to make the space, well, there's just no space.

An eke is so-called because with it you can 'eke out' extra space

LandofSpike now knows that one of the drawbacks of the EPS beebox is that it doesn't have a designed-in option of fitting ekes into its system.
Which is a bit pants.
However, this becomes an opportunity for LandofSpike to put his legendary carpentry skills into practise and supplement his EPS hive with a custom built, homemade wooden eke.
It'll be ready for winter when we'll again need that space above the brood box to house a big lump (that's a technical term) of fondant.





So with everyone now up to speed on ekes, even though we haven't got one yet, and a big blob of thymol sublimating nicely on top of the frames we can rest assured that the housekeeper bees are just starting to distribute the stuff around the hive. 
Best of all the varroa are just starting to get a nice big dose.


You can run but you can't hide, my pretties...

The Honeymoon's Over


LandofSpike's first seven days of beekeepery have not been the best of times for his lovely new Buckfast bees.

This post was meant to recount the transfer of his colony from the travel nuc to the main BeesofSpike hive.
The transfer was totally successful but unforeseen events mean that the report must wait a bit longer.

I find myself instead documenting a week of problems for the BeesofSpike. 




Problem Number 1: Appalling Weather for Bees


The weather has been atrocious over the last week.
Yesterday was the worst of the lot, it chucked it down all day. 
Just like today. 
It's still raining now, as I type.
In fact, it has tipped it down every day for the whole week. 
It was even raining when the BBC Weather Report was claiming that it was sunny.
And the forecast for next week looks just as bad.



And all the while that it's raining my workers are unable to forage.
This is bad news for a small colony of bees that are already into July and have got limited time to get themselves strong enough to survive the winter.
The bees need every bit of good weather they can get.
Although even in the rain we can see them trying their best.







In the meantime I've been leaving the varroa board in place.
The varroa board is the sliding removable tray at the very bottom of the hive that catches everything that would otherwise fall to the ground.
In this way I can monitor what's going on inside the hive by analysing what drops out of the hive.

And after a particularly heavy rainstorm i found... 




Problem Number 2: Rain Incursion


There was water on the varroa board.
That shouldn't be there.

Drat
Surely the hive wasn't leaking from above. 
It wasn't.
Therefore it could only be one of two things.
Or both of them.
a) the hive entrance is quite open at the front and it's possible rain could get in that way.
b) the tray protrudes from the back of the hive by approximately 3cm so rain can fall directly onto the rear of it.

So, to protect the back, I put a length of 2x1 across the width of the hive stand, just above the tray, to act as a little roof.
For the front, I put a couple of tiles under the back feet of the stand to tilt the hive forwards a bit. 
I now realise that setting it up meticulously spirit-level horizontal was a bit of a mistake.
Hopefully the slope will encourage sitting water to not drain into the hive.

On further advice from Beeguru1 I'm going to tilt it forward a bit more tomorrow. 
As much as 15* is fine so the bees will have to get used to being on a bit of a slope, although hopefully a slope is better than a puddle.



On further inspection of their varroa board, i noticed that along with some encouraging pollen and wax debris, a couple of legs, two wings, an antenna and other assorted detritus, that there seemed to be more varroa activity than i was expecting.





Problem Number 3: Varroa Mites


When varroa mites drop to the bottom of the hive they fall through the cunning wire mesh screen and get trapped on the oily surface of the varroa board.

Not nice
Yesterday, across the whole board, I counted approximately 15 mites.
I cleaned and reinserted the board and today, 24 hrs later, there were about 17 new ones.

And magnified, using the LandofSpike makeshift optical device. Really not nice


In addition, this morning, I found a bee on the landing board, struggling to walk and staggering in circles.
It had stunted wings and a varroa mite onboard its back.

Two ominous mite counts and that poor sad bee infested with that grisly little beast pointed to only one conclusion.
I consulted Beeguru1 and he confirmed that it looked like the colony had a varroa infestation and that we needed to get it treated double-quick.

It's therefore time to get some Apiguard into the hive.
I've got some on order but I need it now. That means a trip across town to the local(ish) Bee Supplies Shop on Monday morning so the fightback against varroa can start as soon as possible.



And so the honeymoon period's over rather sooner than I expected.
My poor bees most certainly arrived at the BeesofSpike Apiary with varroa already on board.
But hopefully, this is where their luck starts to change.
Seeing just that one horribly damaged and distressed bee really underlined for me the consequences of getting it wrong. I've now got a chance to put it right.


Every crisis can become an opportunity, a crisitunity, as Homer Simpson once said.
The more things that go wrong, the more I learn and the better and more capable a beekeeper I become.
Which would imply that after a first week of appalling weather, water incursion and a varroa infestation, if it continues at this rate, I'll soon be the most experienced and battle-hardened beekeeper in the country.
