October Apiary Notes

Now we are into October the weather has turned more autumnal although the bees are working the ivy during sunny spells. In fact some hives are working as if there is summer flow so they have a super to collect this last bout of activity. The presence of a super prevents the brood nest from becoming congested with stores and allows the queen to continue laying, albeit at a lesser rate.

Feeding should be about finished by now. Bees are reluctant to take stores down If the weather turns cold so, if some colonies need topping up it is better to do it sooner rather than later.

The next job on my list before winter is to place mouseguards over entrances although I normally wait for the first frost before doing so. Mouseguards can knock off pollen loads from incoming foragers and pollen is vital for colonies while brood is being produced. Do tap the brood box before putting mouseguards in place – otherwise you could be trapping mice in the hive for winter!

The last job before winter is to wrap hives with wire netting to prevent woodpeckers damaging brood boxes. I am in the process of moving netting to apiary sites in readiness for this tedious job. If the winter is mild we can get away without nets but if there is a cold snap woodpeckers can do a lot of damage in a short time. Trying to put netting in place in bad weather is not high on my list ‘nice’ jobs so I prefer to do it in benign conditions. That way I know colonies are pretty safe until springtime.

As the active bee season is now over I will send out apiary notes every couple of months until spring. Meanwhile, do try to get along to Improver sessions that are held are the county. They are a great way to acquire beekeeping knowledge over the winter in readiness for next the season. (See page 37 of the Yearbook for Improver group leaders.)

September Apiary Notes

Our bees are now preparing for winter and it is time for us to make sure colonies are in a good condition to survive the winter.

My hives were all treated for varroa during August and this year I used Apivar. It is important to vary the type of treatment applied each year so that the risk of mite resistance is reduced. If you haven’t treated yet choose a treatment that isn’t temperature dependent. Apiguard is less effective in lower temperatures and can leave many mites in the colony at a time the winter bees are produced.

This coming week I shall finish moving colonies to their winter quarters from sites where they have foraged this summer. One of my main aims over winter is to provide as much shelter for colonies from all winds even if it means placing tens of colonies in one site. However, there must be enough pollen resource for such a site but nectar is less of an issue as the bees will be fed over the coming month. In my experience winter losses are reduced if shelter is provided. Weather presenters tell us of the ‘wind chill factor’ and this applies to bee colonies as well as humans!

Over the coming weeks I shall feed my bees Ambrosia as I find this an easy way to feed bees. It is an inverted sugar so there is less work for the bees when processing it. My aim is to finish feeding by the end of September and preferably before ivy comes into flower. Ivy honey can cause issues for bees if they have too much. It is associated with dysentery and can weaken a colony or cause it to die out. So when a colony has been fed enough syrup I place a super back on the hive to collect any ivy honey the bees may bring in. It is conventional super placing, i.e. brood box, queen excluder, super and then crown board. The super can be removed around mid November and processed but the honey will probably have set at this point. The reason I add the super is to allow space in the brood nest for the queen to lay. If bees bring in too much ivy it could take up too much nest space and thereby reduce egg laying .

If you added several frames of foundation to the brood box earlier in the season check if the bees have drawn them out fully.  It may be necessary to move outside frames inwards by one otherwise the bees may not utilise the outside frames for stores. This means they have less food for winter and could starve next spring.

When feeding with granulated sugar it should be a strong solution, that is 2lbs of sugar to a pint of water. Only use white granulated sugar as other forms are harmful to bees. An easy way to dissolve sugar in bulk is to use a paint stirrer attached to a power drill. Place around 20lbs of sugar in a 5 gallon container and add hot tap water to cover the sugar. Stir with the drill for a minute or two and the sugar will have dissolved sufficiently. When I used granulated sugar in the past I was able to process around 100lbs in about an hour.

Finally, assess colonies and ensure they are queen right and look strong enough to make it through winter. It may be better to unite two weak colonies in the hope that a single one will survive rather than two weak ones die out.

Swarming Season

It’s that time of year again when we can expect to see honey bee swarms. Hives are beginning to get stronger and may soon decide to swarm. We have already seen some swarming and the recent warm spell of weather will contribute to this tendency.

If you are a member of the public and suspect you have a honey bee swarm our volunteer swarm collectors may be able to help. See our pages on insect identification and swarm collectors for assistance.

Food for thought ?

Bees on Compost

The bees in my garden have completely ignored the large patch of Snowdrops planted especially for them.  However, they have adored the pots used for growing tomatoes last year, with leftover but “spent” organic compost.  I have seen this kind of behaviour before, but never to this extent or so persistently.  What are they after?  Mineral nutrients?  Something else too?  Mycologist Paul Stamets argues that in forest conditions bees might also derive essential benefits from fungi, and mushrooms can preserve them from virus infections – and save the world.  Google if you are interested!

Beautiful but Dangerous!

As pictured at Queen Bee Day: Beautiful but Dangerous!

One queen has lived in Gill Brewer’s memory since 2009!  Her daughters stung her apiary landlord and his dog.  She culled the whole hive because the extreme aggressive-defensive behaviour might have been passed on to other colonies through the drones.

Our training day on ‘The Queen Bee’ at Flitwick Village Hall dealt with many fundamental issues of real practical importance, attracting 48 participants. Among the matters covered were just how the female egg becomes a fully-fledged queen, pros and cons of different strains of bee, different queen rearing methods and whether to buy in professionally produced queens – or raise our own “British Mongrels”, with a clear majority perhaps leaning towards this approach.

We were privileged to have Peter Tompkins as one of our teachers, who gave us with insights into pioneering bee research at Rothamsted as well as the benefit of his huge fund of know-how about working successfully with bees.

Nosema Clinic

The Association is pleased to announce  that John Rhodes will be running a Nosema Clinic on 10 March. Please see event listing for more details Nosema Clinic.

Honey Show – Honey Festival

Woburn Abbey courtyard and gardens provided a beautiful setting for a new event in our calendar, the Honey Festival on Saturday 30 September.  A wide range of stalls were there to appeal to visiting members of the public, including the ever-popular observation have, skep-making with Ray Smith, and a much-frequented display of local honeys and other edibles for tasting and purchase.  Many members of the Association ran the stalls or helped to talk to the 450 or so visitors, who also had full access to the Honey Show inside.

Around 10% of members entered for the Show this year, with over 250 items.  The judges praised the excellent organisation and overall quality of the entries.  One of the many eye-catching and prize-winning items was a nativity scene ingeniously constructed from beekeeping materials, with figures cast in beeswax from a church apiary, using moulds specially made from models hand-carved in Bethlehem.

Show Secretary Fiona Cook commented: “Woburn Abbey was very happy to have hosted Beds BKA, and we were delighted to be there.  The very friendly, positive atmosphere has received much comment.  It seemed to come about from a combination of the welcoming and very professional staff at Woburn and our own ethos and teamwork as a charity, with so many willing helpers.”

Another ingredient may have been the real interest and willingness to engage with bees and beekeeping on the part of visitors: the public attitude has really changed in a very positive direction.

We hope to return to Woburn next year, perhaps in early September in the hope of warmer weather, and on a Sunday, perhaps with other rural crafts represented.

Varroa Treatment

Previously I used Hiveclean as Varroa treatment, both before supers went on in spring and again at the end of summer when honey was taken off. However, Hiveclean has been withdrawn and is no longer available.

So I decided to treat for Varroa this summer using MAQS (Mite Away Quick Strips) which contain formic acid. At the recent Bee Disease Day, Keith Morgan our Regional Bee Inspector, described the best way to apply this treatment: He recommended that mesh floors are closed by inserting the monitoring tray, in order to keep in sufficient fumes, but allow a wide entrance so the bees are not exposed to excessive fumes. Keith also recommended that a couple of supers be placed above the brood box with no queen excluder; allowing the queen to move away from the fumes if she needed to.

In the event I decided to use just one MAQS pad per colony (rather than the recommended dose of two pads per colony) to err on the cautious side, as I have heard reports of queens dying as a result of this treatment. Using a low dose of MAQS will not cause Varroa mites to become resistant to the treatment, as happened with the pyrethroid insecticides in Apistan and Bayvarol.  My mesh floors are homemade and not designed to take a monitoring tray. Luckily I kept my solid floors from years ago and brought them back into use. I moved the whole colony to one side, placed the solid floor on the stand and replaced the hive, including the mesh floor, on top of the solid floor. This allowed the mites to fall through the mesh onto the solid floor for a visual check at the end of treatment. The bees did not have access to the solid floor so they would not remove any debris or mites.

It is not realistic for me to monitor the mite drop in my hives due to the number of colonies I run. So the only way I can assess varroa levels is by forking out drones around June time. But looking at the mite drop after a seven day treatment shows me the level of infestation in each colony.

MAQS is a seven-day treatment. I did not have enough floors to treat all hives at the same time. I was also cautious and wanted to see how colonies fared after treatment. So I treated a few at a time.

When I started removing the solid floors and checking the mite drop, initially I was concerned that the treatment may not have worked well as there were only tens of mites. I was not sure if I was under dosing or whether the volume of the hive was too great.

Then I came to remove the floors from five colonies that have Danish Buckfast queens which I bought last year. These queens are prolific with large brood nests and high populations of bees since early spring. They were very productive in honey gathering and most did not swarm in their first season. The mite drop from these colonies was in the hundreds.  So I contacted Keith Morgan to ask why the mite count was so high. In his opinion strong colonies such as these are Varroa factories. Because so much brood is produced – and Varroa mites reproduce in the brood – there are greater numbers of mites. Also these large colonies produce more drones – Varroa reproduces faster in drone brood than worker brood – increasing mite numbers further. Finally, with no swarming – and therefore no break in brood production – there is no break in mites multiplying. Incidentally, low swarming impulse is another benefit of these queens.

According to the instructions, MAQS can be used with honey on the hive. However, my policy is to remove honey before treating, so there is no possibility of contamination.

We cannot rely on a single treatment per year as mite numbers can build up to dangerous levels.

My next treatment will be trickling oxalic acid in December. This treatment is effective and I have used it for several years. I may give a MAQS pad to my Danish queens next April just to try and keep mite levels low before the colonies build up.

If you haven’t treated for Varroa yet, please do use something soon. Strong colonies which did not swarm this year can be more prone to Varroa damage. It is important to produce healthy winter bees now to keep the colony going till next spring.
