HOW TO CARE FOR YOUR OVERWINTERED NUCLEI

For Maximum Results and Yield!

 

Your overwintered 4-frame nucleus is a live unit of honeybees from the Russian stock, with a laying queen introduced during the summer of last year.  The queen is the daughter of a Pure Russian Select Breeder Queen who underwent a number of tests designed to select for traits desirable to genetically control both mites:  Varroa and Tracheal.  These test also deals with resistance to brood diseases, such as AFB and EFB.

 

It has not been treated with a Check-Mite  or an Apistan strip last fall or this spring.  It may have been treated with formic acid last fall, using the Mite-Wipe application three times, to control varroa.  It was treated with oxytetracycline last fall and this spring against AFB and EFB.

 

This nucleus is capable of producing a good crop of honey this summer.  Your nucleus needs care and attention from you the beekeeper and to maximize its potential for production you should follow these guidelines outlined below.

 

1.           Clean Equipment

1.1.              Use new equipment if you can or disinfect with a propane torch by scorching brood chamber, inner cover and floorboard.

1.2.              Use frames of foundations or new empty combs to fill the supers.

1.3.              Do not use combs of honey from a dead colony, it may contain disease spores in the honey.

1.4.              Discard or cull old dark combs, the ones you cannot see through when holding up to the sun.

 

2.           Location

2.1.              Locate your nucleus in a permanent location that will enhance its productivity.

2.2.              Choose a sunny area, sheltered from dominant winds.

2.3.              Keep away from wet locations where melted snow tends to accumulate in the spring, or where heavy rainfall might also make the immediate environment soggy and humid.  Bees like a dry location. 

2.4.              Elevate your colony from the ground by putting it on a hive stand or a pallet, about 6-9 inches from the ground.

 

3.           Least Disruption Possible

3.1.              When transferring the frames of brood and bees into your full-size equipment, take care not to injure the queen.  Do it delicately, trying not to crush any bees if possible.

3.2.              First, remove all empty frames from the brood chamber, or remove the 4 center frames.

3.3.              Second, you can begin transferring the nucleus by removing the frame of foundation first.  Put in the brood chamber or put aside for later use.

3.4.              Third, gently pry apart the other frames and remove them one by one and transfer them into the brood chamber.

3.5.              Keep them together in the center of the box, making sure they are positioned the same way they were in the nucbox, in relation to one another.

3.6.              Replace or add empty frames on either side to fill the box.

3.7.              Reduce entrance.  Install the inner cover and outer cover.

 

4.           Feed Immediately

4.1.              Your objective is to stimulate and give some food stores to your nuclei.

4.2.              You want to prevent starvation and dwindling.

4.3.              Even if a strong flow of nectar is on you should feed your nucleus to help it develop and grow fast.

4.4.              You can feed it continuously using a top feeder or an entrance feeder.

4.5.              Use 2:1 sugar syrup (2 parts sugar - 1 part water) by weight or volume, it makes no difference.

4.6.              Do not feed dark honey, brown sugar or molasses.

4.7.              If you elect to supply the nuclei with combs of honey, make sure it is white honey and free of disease or contaminants, such as pesticides or antibiotics.

4.8.              Do not underestimate the potential of your nuclei.  The goal is to ensure the nuclei builds up without interruption because of inclement weather in the spring.  It takes a lot of feed to raise lots of bees.

4.9.              Stop feeding whenever the nuclei has gained some weight, and the brood chamber is full of bees.

4.10.         Do not overfeed, because the queens need enough room to lay eggs.

4.11.         Heavier is not the better in the spring.

 

5.           Miticide Strips and Medication

5.1.              Your nucleus was NOT given a mite strip; either Apistan or Check Mite to help controlling Varroa Mites on the day the nucleus was made.

5.2.              It may have been treated with formic acid, using the Mite-Wipe method, whenever necessary.

5.3.              It was treated with Oxytetracycline last fall and this spring, for the prevention of AFB American Foulbrood and EFB European Foulbrood.

5.4.              In our opinion, you need not treat again for either of these diseases or parasites before next fall.

5.5.              The only medication that we recommend to give the nuclei now is Fumagilin to prevent nosema.

5.6.              The direction of the label calls for 1 treatment only.

5.7.              1-2 litres of 2:1 sugar syrup, containing about 2.5 grams of the product.

5.8.              Equivalent to 5 ml or 1 teaspoon per nuclei.

5.9.              If you install a Check-Mite strip in your nuclei, be aware that this product is very strong and can kill the nuclei instead of helping it.  This product is not intended for small colony of bees.

5.10.         Do not use the formic acid pad Mite-Away II on a small nuclei, it is not intended for colonies smaller than 5 frames.  The harmful vapour will also kill the nuclei.

 

6.           Summer Management

6.1.              When the population has reached about 9-10 frames, add another brood chamber or a queen excluder and a honey super.

6.2.              Make sure to add supers as they are needed to make sure the queen has enough room for her to lay abundantly.  The queen must not become honey bound, or her population of bees will dwindle in the fall and they won’t winter successfully.  The queen’s brood nest must not be restrained from May until August.  The queen must be allowed to maintain a large population of bees until the end of summer.  Otherwise, the bees will be too old to spend the winter, leaving the colony with too small a cluster.  The colony needs lots of young bees being produced in September.

6.3.              SUGGESTION:  When the colony has grown in population to cover about 9 to10 frames, add a queen excluder immediately and one empty super for honey.  The bees will move newly collected nectar above excluder and the queen will have enough room to lay eggs.  Do not underestimate your bees!  Add supers as needed; to make sure they have enough room.  It is possible to get 175 lbs in a good summer from a single nucleus!

 

7.           Varroa Survey

7.1.              You should monitor the population of Varroa mites in your colony.

7.2.              You should survey your colonies twice during the season.

7.3.              End of June, beginning of July AND end of August, beginning of September.

7.4.              Survey a minimum of about 25% of your colonies.

7.5.              Install a Sticky Board on the baseboard for a period of 48 to 72 hours approximately, to collect dead mites falling by natural death.

7.6.              A sticky board is a piece of white poster board about 8 ½” x 11” covered with a sticky substance such as Tanglefoot, sold at Lee Valley Tools & Garden to catch fruit flies in orchards.

7.7.              Record the times and dates you put it on and remove it, so you can calculate the 24-hour average of natural mite fall by natural death.

7.8.              You must cover the cardboard with 8x8 mesh to prevent the bees from cleaning it.

7.9.              Retrieve it the sticky boards and bring them home to examine.

7.10.         Count the number of varroa mites on each sticky board and record.

7.11.         Calculate the 24-Hour Mite Drop.

7.12.         24-Hour Mite Fall=# of mites x 24 hour / # hours of survey.

7.13.         If 24-Hour Mite Fall # approaches or exceeds 10 mites, you must consider treatment, otherwise you risk damage or losing the colony during the winter.

7.14.         If 24-Hour Mite Fall # approaches or exceeds 20, you must treat immediately, otherwise you risk losing the colony during the winter.

7.15.         The decision is yours to make.  These guidelines are for your own information and are there only as a help.  We do not make any guarantees in offering advices and accept no responsibilities if you suffer damage to your bees because you followed our advices.

 

8.           Fall Treatments

8.1.              Follow the recommended treatments as described in the Ontario Recommendations for Honey Bee Disease Control located on the OMAF website (Ontario Ministry of Agriculture and Food).

 

9.           Feed Early

9.1.              Remove honey supers early in September and feed immediately before the daytime temperature falls below 15 Celsius

9.2.              Do not leave surplus honey for the bees.  Honeybees overwinter well on white sugar honey.  Fall honey granulates hard and fast, and the bees cannot feed themselves properly.

9.3.              Feed your colony early in the fall, in the month of September, early October.  This is to insure your bees has enough warm weather to help them evaporate all the excess water from the feed and keep them nice and dry for the coming winter.

9.4.              Feed them using 2:1 sugar syrup (2 parts sugar: 1 part water).

9.5.              Give them enough feed:  about 60 lbs .

9.6.              Remember they have to last until the next dandelion flow in May of next year, and raise brood in early spring also.

9.7.              Sometimes the weather in April or early May is unreliable.

9.8.              That way you rarely have to feed them in the spring.

 

10.       Overwinter Properly

10.1.         Make use of wintering boxes with wood shavings or else use some of those valuable winter packing available at most bee supply house.

 

11.      Next Spring Treatment

11.1.         Monitor your colonies again, using the sticky board method.

11.2.         If you have done a good job last fall, you may not need to treat again before next fall.

11.3.         If you need to treat, consult the Ontario Recommendations for Honey Bee Disease Control.

 

12.      Support and Attend Beekeepers' Association

12.1.         At the local level, provincial level OBA and national level CHC.

12.2.         You can learn a lot from attending and participating in beekeepers’ meetings.

12.3.         The last research and techniques are discussed on a regular basis.

12.4.         They have hands-on sessions or how-to demonstrations.

12.5.         You can ask questions to experienced beekeepers.

12.6.         Experts in the fields show presentations of research results

12.7.         You can visit apiaries and honey house facilities.

12.8.         They organize courses for beginners and other topics.
