Beekeeper Fred's Apiary Update
I performed a sound check of all my hives today using a stethoscope. That involved a hike through the snow of
about 1 ½ miles to reach all of them. As
previously stated I took 40 hives into winter.
Based upon a quick and dirty early October inspection I had classed 27 hives as strong, 10 as medium strength and 3 as weak. As of today 38 hives are still humming. Of the two lost since my last report, one had been classed as weak
and one medium.
Although I have lost 2 hives so far I am happy with the
results (5% loss) to date. This time
last year I had already lost 23% of the hives.
This is a significant improvement
over last year, which I attribute to steps taken back in August. A) Heavily feed all first year hives (that free sugar sure helped), B) Don’t try to overwinter any hive started
after June, C) Treat for mites in mid August and again in September and October,
D) cull or combine weak hives.
Both of the lost hives had been wrapped with a BeeCozy. As stated previously I have tracked hive
survival of wrapped versus unwrapped hives for several years and have seen no difference.
One hive appears to have mice in it. Tomorrow I will slip in a little piece of rat
poison to try to remedy that situation.
There is a long way yet to go until spring, but the winter solstice has
passed and the amount of sunshine is slowly increasing day by day.

FEDERAL HELP??
If interested in getting federal money for bee habitat read the following links. This help is usually limited to farmers (others need not apply) and the recipients must jump through the usual bureaucratic hoops, but don't let that discourage you.

Winter Thermoregulation
This links provides analysis of winter hive temperatures. The study was conducted in a 5 year span in Madison, Wi. The data allowed the analysts to come to a number of conclusions which are at the end of the article. The ones I thought significant were:
1) The hive makes no attempt to regulate the temperature outside of the winter cluster.
2) Insulating does permit the cluster to be somewhat looser; meaning it is spending less energy to maintain cluster temperature.
3) In the Madison area both insulated and uninsulated hives should have no survival issues under normal winter conditions.

VARROA VIDEOS from the Honeybee Health Coalition
Back to varroa control again. Here is a link to a website that has a set of videos decribing varroa mite sampling and the all of the most used varroa control methods. Watch the videos and choose the method you feel will be most effective for you. One thing to remember is that if you want to call your honey organic you will be limited to oxalic or formic acid as a means of chemical control.

WHAT'S HAPPENING HERE
Received this photo taken yesterday on December 14th. It was a high of about 10 degrees yesterday. On the outside of this hive there was a mound of obviously frozen bees. The heads of most bees were pointing towards the entrance. The hive is apparently doing fine. It appears these bees are mostly drones that had been evicted from the hive. My theory is that this package queen did not get the message to stop raising brood earlier this fall and now that crunch time has arrived the drones are being evicted.

WINTER WEATHER
The really cold weather will soon be upon us. Going down to -15F this weekend before a warm up to the balmy 20s. Nothing we can do now but wait out the cold. This extreme cold is one reason for utilizing cold acclimated bees. Nature's Nectar blog has a few words on the hazards of late fall feeding. Read and be smarter for next year.

WINTER 2016-2017 by beekeeper Fred
I think with the past weekend’s snow we can all agree that
winter is upon us and our bees.
Hopefully we all did our best during the long warm fall to prepare our
bees to survive the coming months of cold weather. Again this year I will periodically report on
how my hives are surviving. As you can
tell from previous year’s reports I am not a master beekeeper and have on
occasion suffered heavy winter losses.
Some years are better than others.
Each year I try to learn a little more by reading, hard knocks and
conversations with more successful beekeepers and then apply those lessons to
increase the chances of winter survival for the bees in my apiary.
Last year my final winter survival was a miserable 50%;
worse than some and better than others.
If I had to make my living at beekeeping I would probably be out of
business. In the spring I surveyed
several of the more successful beekeepers in hopes of learning their techniques
to high survival. Here were the items
that seem to have a great influence.
1)
Never try to take a weak hive through the
winter. Put another way: Only take a
strong hive into winter. Weak hives should be combined with another
hive.
2)
Treat for mites in mid August. This permits the hive to raise winter bees in
a fairly mite free environment.
3)
Check mite levels after the August treatment and
treat again as necessary.
4)
Do not start new hives after June. They simply won’t have time to develop large
enough populations and food stores in the remaining summer and fall. In my area the honey flow is essentially done
by mid-July.
5)
Heavily feed all start-up hives through August
and September.
6)
Minimize use of spring packages since the
genetics of the factory queens are not ideal.
7)
Incorporate mite resistant bees into your
operation.
So how did I do incorporating these recommendations?
1)
In mid-August after the honey harvest I culled 5
hives from my operation by eliminating the weak hive’s queen and combining the
bees with hives of medium strength.
2)
After the honey harvest I treated all hives
(except one) with a full dose of MAQS (formic acid). The one exception was the hive with a Purdue
Ankle Biter breeder queen. I did not
want to chance killing the queen during the treatment.
3)
I cheated on the “check mite levels” post
treatment. So yes I was lazy. Instead in mid-September and mid-October I
treated all hives with oxalic acid vapor.
4)
I did not start any new hives this year after
July 1st except for two swarms I managed to catch in
mid-August. These were immediately re-queened
and given liquid feed. A third swarm
voluntarily occupied an empty hive in mid-August.
5)
In early August I began feeding the 2016
start-up hives and also any hives that were not making a honey surplus. Thank
god for that free sugar from the bakery!
6)
I reduced my package purchases this spring to
eight and perhaps that was a blessing.
Through the course of the summer only 2 of those packages did
anything. The others just never got
going. Four of them needed re-queening
and two more superceded their queen. I have my fingers crossed and hope to not buy
any packages next spring. At least
that’s my aim.
7)
This year I raised and incorporated both Russian
and Purdue Ankle Biter stock into my operation.
Both strains are noted for their mite resistance and ability to
withstand northern winters.
Although I did not make mite level checks on all hives as
suggested I did learn how to perform these checks. This year I upped my game by learning how to
use sticky boards, alcohol wash and powder sugar roll mite check methods. After a little reading I plan to standardize
on the powdered sugar roll method next year.
ALL
of the hives I checked did have mites of varying levels; even after those three
(3) mite treatments. All post-treatment mite levels showed my hives
below mite limit recommendations (for those few hives I did check). The fact that I did not check all hives is an
obvious shortcoming. Overall I think my
hives are in the best shape going into winter since I have started beekeeping.
As of October 15th I decided to take 40 hives
through the winter. I tried to gauge
hive strength by quickly observing the number of frames covered with bees below
the inner cover; strong 8-10 frames, medium 6-7 frames, weak 5 or less. Twenty-seven (27) hives ranked strong, ten (
10) medium and three (3) weak. (Yes, I know I should have eliminated those 3
weak ones) Twenty-five (25) are of
Russian stock, eight (8) of Ankle Biter stock, four (4) Carniolan stock and 3
miscellaneous or unknown. Note: Only a
few of these a “purebreds”. All queens I
raise are open mated and therefore their offspring are mongrels that hopefully
retain the beneficial traits of their mother.
This year I will again compare the survival of wrapped
versus unwrapped hives. In the previous
two years I have done this there was no difference in survival rates. I will see if this holds true again this
year.
Unwrapped hive in foreground/BeeCozy wrapped hive in background
I periodically check the hives by simply listening with a
stethoscope for the loud buzz of the bees though the upper air vent hole. I am happy to say as of December 1st
all hives were buzzing. A below zero
cold snap will arrive next week which will test the weaker hives. But as we all know crunch time comes in
January and February . Stay tuned.

CONTAMINATED HONEY AND NOT FROM CHINA
Here is an article from the Des Moines Register that reports glyphosate contamination in American honey samples. Actually, its not surprising since glyphosate is one of the most popular herbicides in the US.

DECEMBER 3RD CLUB MEETING
The primary topic of the December meeting involved a report from club members who attended the Brown County Beekeepers Seminar in October. Patti Ingram provided a bullet point slide show with the highlights of the seminar. Other attendees provided additional background information. Topics covered in the seminar were winter survival and overwintering nucs.
What I gained from their information is that the overwintered nucs were actually regular deeps that were modified to be side by side 4 frame nucs. The two nucs could thereby share heat through the divider in the center. These nucs were also stacked at least 2 deeps in height.
A thank you to Patti, Mark and Paul for their report.
Septembers minutes were read and approved. As was the treasurer's financial report.
The topic of public outreach was delayed until the January meeting. All members were invited to provide both ideas for public outreach, but also do recruiting of personnel to support any activity.
Free kits to perform powdered sugar mite checks were distributed all interested club members. The meeting then adjourned and members went to sample product-of-the-hive treats brought in for our enjoyment. Baklava, honey glazed pecans, honey spiced chicken, mead, honey brittle, and honey cookies were sampled by club members.
The next meeting is tentatively scheduled for January; exact date TBD.

FRED'S MITES
After reading the varroa mite articles in the Nature's Nectar blog and seeing sticky board pictures sent in by beekeepers Gerard and Grandpa Jack I decided to do another mite check on one of my hives. I chose to utilize a sticky board so I could directly compare with the pictures from those three sources.
So Wednesday I slipped a sticky board into Hive U. This hive has a Ankle Biter queen. I had previously treated the hive with MAQS in mid-August and again in mid-September and mid-October with oxalic vapor. I was not expecting to see many mites. When I removed the sticky board 24 hours after another oxalic vapor treatment I counted 19 mites.
Mites are circled.
So now for a big question. Are 19 mites good or bad? I had absolutely no idea. Gerard indicated this was much lower than what he had seen from his hive. Like most beekeepers I was not able to find a handy go/no go recommendation for the method I used. The closest I found were limits ranging from 12 to 50 mites for a "natural" mite fall onto a sticky board in 24 hours. "Natural" mite fall occurs from mites dying and dropping or being groomed and dropping or just losing their grasp on a bee and dropping. I could not find a limit for my accelerated method which used oxalic vapor.
In a beehive at this time of year the population is slowly declining. Right now I am guessing the population is in the 20,000 to 30,000 range. I've seen recommendations that mite infestation levels should be in the 1 to 5% max level. A 1% level means there are about 300 mites on 30,000 bees. Oxalic acid vapor is reputed to kill 95% of the mites on bees (not those on capped brood). 95% of 300 is 285. So potentially on a "good" 1% hive I could kill 285 mites. From this I am making the inference that my 19 mite fall in 24 hours is "GOOD". Since I have treated all my hives in a similar manner I am feeling good about my chances for good winter survival. It looks like the snow may start flying next week so my outdoor beekeeping is done until spring other than periodic checks tosee if the hives are still humming. Stay tuned.
PS-you probably saw that I treated my hives with 2 different natural acid compounds; MAQS (formic acid) and oxalic acid. MAQS is reported to be able to penetrate the brood cell and kill juvenile mites. MAQS is also reputed to have a higher potential for killing the queen; therefore I was hesitant to apply it more than one time. MAQS also needs warmer temperatures to be effective. Oxalic acid can be used at lower temperatures; down to 40F. However, oxalic acid does not penetrate into the brood cells. It is most effective after the queen has stopped laying and all capped brood has emerged. I had also just received the oxalic vapor tool and was playing with it.

RE-QUEENING RECOMMENDATIONS FROM IRELAND?
This article is about beekeeping and bee winter survival in Ireland. However, it also cites some European studies regarding queens. The two most applicable to Wisconsin are:
1) Locally raised queens have a longer survival than purchased queens; an average of 83 days longer.
2) It is better from a winter survival standpoint to re-queen in mid-summer. Re-queening during late summer or early fall is not as successful in getting the hive through winter.

HOMEMADE VARROA TEST KIT
We have been harping you about the need to control mite levels in your hives. Controlling the mite levels is key to minimizing the chances of deadly bee viruses from getting out of control. Here is a simple homemade varroa check kit. It can be used for either powdered sugar or alcohol wash checks. The magazines and blogs that I read indicate that both powdered sugar and alcohol wash yield similar results.
Assembled varroa tet kit.
Cut out bottom with Exacto knife or equivalent
Place screen between containers
Screws and nuts
To make this varroa checker you must be a cheesehead. I think all members of the ECWBA qualify. First eat the cheese out of two spreadable cheese containers. Next cut the bottom out of the containers leaving a lip around the outside edge. Sandwich a piece of screen between the two containers. Join the containers using 3 or 4 screws and nuts. WhaLa! you now have a varroa mite checker.
If you plan to use this with alcohol also place a bead of RTV rubber at the joint of the two containers.
Most varroa checks recommend using 300 (1/2 cup) of bees. Place a mark 1 1/4 inch from the bottom of one container which is the lvel of 1/2 cup or 300 bees.
Place 2 teaspoons of powdered sugar in containers. Scrape 1/2 cup of bees from a brood frame into top container. Replace lid. Shake vigorously for several minutes. Towards the end of the shake allow the powdered sugar (and mites) to fall through to the lower container. Remove lid from lower container over a white sheet of paper and count the mites. Pour the aggravated bees back into the hive. For 300 bees 3 mites equals 1% infestation; 6 mites equals 2%, etc. The most commonly seen limitation is 3% or 9 mites. If you have 9 or more mites you should treat your hive. If you are of the "live and let die" persuasion at least you will know why your bees have died. NOTE: Some experts are now recommending a 1% level as the treatment threshold.
For those club members that might not have cheese containers I will be bringing to the December club meeting about 6 sets of parts to be given away on first come/first severed basis.
Cut out bottom with Exacto knife or equivalent
Place screen between containers
Screws and nuts
Secure together

A Primer for Potential New Beekeepers by beekeeper Fred
The following recommendations are based on personal experience and extensive reading on the plight of the honey bee. As a new beekeeper you will soon find out that every beekeeper has his own experiences and opinions. As a new beekeeper you will need to sift through all of this advise and come up with a plan of your own for raising and maintaining your bee colonies.
Potential new beekeepers often enter the hobby with
altruistic goals. Most have heard of the
plight of the honeybee and after reading various articles think that they can
immediately become successful beekeepers.
Many potential beekeepers become enthralled with the idea that left
alone the bees will naturally develop mite and virus resistance and that
everything will be wonderful. This
sometimes, but rarely, happens in isolated areas where an apiary is free of
outside influences. It also takes years
of dedicated effort for this to occur. In the beekeeping community this approach to
beekeeping is sometimes called the “Live or Let Die” or “James Bond”
method.
Every beekeeper knows that the European honeybee is beset by
varroa, tracheal mites and viruses. In
combination these three factors can cause the demise of a colony of bees during
the additional stress of winter. New
beekeepers will quickly be taught this lesson by the school of hard knocks when
they lose the majority of their bees the first winter. Ideally it would be in the best interest of
the bees to allow them to develop via natural selection the ability to
effectively neutralize these pests. Natural selection has the nasty habit of
killing of the weak. The double whammy
of varroa and viruses if left uncontrolled frequently results in 30 to 100%
hive loss over the winter. Such
horrendous losses are not necessarily in the best interest of beekeepers who
are interested in honey production and selling pollination services. Several approaches have been developed by
beekeepers to hopefully end up with the same end result; honeybees that can
survive without chemical intervention.
The key to helping the bees survive is understanding the
relationship between the bees, varroa mites and the viruses. The honeybee has developed good natural
defenses against virus transmission in the colony. However, the recent arrival of the varroa
mites has upset the equation. The mites
feed on both the adult and larvae bees.
In addition they move between bees. Therefore any virus infection in the colony
gets transmitted from bee to bee by the varroa and can kill a colony if the
mite infection rate is too high. Controlling the level of mite infestation is the
key to controlling viruses.
The first thing to be said in a discussion on bee
survivability is that 99% the queens received with packages are raised from
long established genetic lines. These
genetic lines were developed to maximize honey production and the docility of
the bees. These established genetic
lines have NOT shown the ability to withstand the assault of the three pests. Also to date most major queen breeders have
NOT been motivated to change their breeding stock to more resistant types. So
every time you purchase a package to replace your winter’s losses you are
simply getting more of the same inferior genes.
If your beekeeping philosophy trends towards the “live or let die” approach
you will probably be purchasing packages every year until you give up and quit beekeeping
due to the expense of buying packages every year. Also, when you purchase these inferior queens
you are importing the poor genes into not just your apiary, but also into your
neighbor’s apiaries since bees tend to mate with drones from other areas. Sad,
but true.
There are various approaches to giving your bees a fighting
chance against varroa. First is to
provide them with a little aid in their fight with their antagonists. This involves the use of chemicals (either
natural or artificial) in an attempt to control the mites. History has shown that the mites have
repeatedly developed resistance to artificial chemical treatments. Over the last 30 years several chemical
treatments were the silver bullet for controlling mites for a few years until
the mites via natural selection developed resistance to them. There are currently 4 or 5 treatments that
are still effective, but the efficacy of these may also decline in the
future. New beekeepers should consult
with experienced beekeepers in their area on the use of chemical treatments. Chemicals
that kill mites can also kill your bees and also do harm to you if not applied
to the proper manner. Also remember that the continued use of
chemicals to control mites will not aid the bees in developing a natural
resistance to mites. Most hobbyist
beekeepers, who are mainly interested in honey production, will probably end up
using a chemical approach for controlling mites.
Other less invasive methods include screened bottom boards
for the hive, drone brood trapping of varroa, and temporarily caging the queen;
all of which can also aid in the fight against varroa. A new beekeeper needs to understand the pros
and cons of these approaches and also understand their limitations.
The next (and more difficult) approach is to develop genetic
lines of European bees that can control the mite level themselves. Other types of honey bees (Asian) have
developed the ability to coexist with the varroa mite. There are many reports of beekeepers who
have not chemically treated their hives of European bees for many years and
their bees have also developed resistance to mites. Only very dedicated
beekeepers are likely to succeed in developing resistant bees because the
selection process is long and difficult. The time frame for those who have been
successful is on the order of decades. However, hobbyist beekeepers can take the step
of procuring queens that have these resistant traits and getting these genes
into their apiaries. Varroa resistant
lines include Varroa Sensitive Hybrids (VSH), USDA Primorski Russian, Buckfast,
and Purdue Ankle Biters. The VSH,
Buckfast and Purdue Ankle Biter strains were developed by beekeepers or
scientists performing slow and meticulous data gathering, analysis and then
long term breeding programs. The
Primorski Russian bees were a line of European honeybees that were exposed to
mites in the Primorski region of Siberia and over a period of 100 plus years
underwent natural selection and finally only resistant bees survived. New beekeepers should read up on these resistant
strains of the European honeybee either by doing internet searches or reading
about them in one of the bee magazines; such as American Bee Journal or Bee
Culture. Users of these specialized
strains have reported varying degrees of success.
It is recommended that new hobbyist beekeepers should NOT
follow the “live and let die” philosophy for two reasons. The first is that you will most likely lose
your bees in the winter do to the varroa and virus effects. All beehives in the US now contain varroa
mites; your new hive isn’t any different despite your wishful thinking. You can’t see them (the varroa), but they ARE
there. The second reason is that the
varroa from your hive will migrate to your neighbors’ hives. Bees inherently drift between hives;
especially the drones. Varroa use this
phenomenon to expand their territory and populations by hitching a ride on the
drones. Also when your hive dies (as it
most likely will) robber bees will come to loot the stored honey. In doing this they will pick up mites and
return them to their home hives. Thus
you are unknowingly infecting your neighbor’s hives with varroa.
In summary every new beekeeper should remember:
1)
Every time you buy a bee package to re-stock
your hive you are importing same inferior genes into your apiary.
2)
Following the “live and let die” philosophy,
although altruistic, will most likely result in high colony losses in your
apiary and is harmful to your neighbors’ bees also.
3)
If truly interested in being helpful to the
honey bee you should incorporate varroa resistant genetic lines into your
operation; the sooner, the better.
4)
Unless you have unlimited financial resources
for purchasing replacement packages it is wise to understand and apply a mite
control program. After you have become
more knowledgeable and are successful in getting your bees through several
winters you can then begin experimentation.

NEW VIRUS?
A new virus, the Moku virus, has been identified in Hawaii. It appears to be similar to Deformd Wing Virus and Isreali Acute Paralysis Virus and can also be transmitted by the varroa mite. Here are a few links. Unfortunately I haven't yet found a description of the symptoms associated with the virus. On the plus side it appears that the presence of the DWV virus controls the Moku virus. So far it has not been reported in the continental US.

WARM WEATHER
Here is a link to a blog article discussing our warm weather. The article also stresses the need for all beekeepers to treat for mites. If you don't like using hard chemicals then you should consider either formic or oxalic acid treatments.

INTERESTING BLOG SITE
Here is a link to a blog written by a beekeeper in Stillwater Minnesota, which is about 100 miles north of Central Wisconsin. Looks like he is also computer savvy. In this posting he is writing about tasks for October and then has several short videos on: Oxalic Drip Application, Wintering Hives in Minnesota and Installing a Bee cozy. In general a lot of useful information. I will try to periodically visit this site and pass on items applicable to our locale.

2017 PACKAGE INFO
As many of you are aware Lee Hiene has retired from both Dadant and the package bee business. He passed his package bee business to Tim Wilbanks. Here is an email I received from Tim regarding spring 2017 packages. As usual the ECWBA does not endorse any suppliers. Tim's email address is timwilbanksbees@gmail.com The following is Tim's email.
Our family is excited to start the process of gearing up for the Spring 2017 package bee season. We will continue to provide the great service and quality bees from Northern California that Lee Heine provided for so many years.
This email is to get an idea of how many packages, what size, and when you'd prefer to receive them this coming Spring. It may seem early, but I'm currently receiving lots of orders and starting to compile the list. I'll do my very best to accommodate your preferences (e.g. 2lb. vs. 3lb., timeframe, Italians vs. Carnis, etc.).
Prices will not be finalized until after New Year's once pricing from the suppliers in CA is set, but you can put in your order and send your deposit ($10 per package) to my PO BOX listed below. Once prices are set, I will let you know via email. Payment in full is required by March 15th to avoid a log jam at pickup. Of course, you will be able to add or subtract from your order with no penalties as long as there is still availability. Deposits secure your order quantity and give you priority for preferred time frame for packages. As I receive deposits, I'll update my records. Just like last year, there will no longer be any credits for returned cages. Most all of the producers have done away with reusing them.
Mail deposits to:
Heritage Honeybee, LLC
Tim Wilbanks
PO Box 117
Sullivan, WI 53178
We will no longer distribute packages from the Dadant store in Watertown, as Lee did. Instead, my family is currently constructing our new home and building which will serve as the new pick up location for your bees. It is located only a few miles off Interstate 94 at exit 275 between Johnson Creek and Oconomowoc.
Pick up address will be:
N6007 Hillside Dr.,
Sullivan, WI 53178
Please feel free to contact me anytime; I am almost always available at: 319-321-2494 .
Thanks,
Tim

PURDUE ANKLE BITERS
Follow this link to read a paper published last year in Bee Culture on the Purdue Ankle Biter grooming bee. This paper has more detailed data regarding the performance of this bee type in the field. Several club members are now utilizing queens with the Ankle biter genes in their hives. Any means of combating the varroa mite is needed.

SUMMARY of "GETTING YOUR BEES THROUGH THE WINTER"
This is a short book written by David Burns. It is available as an E-book from Amazon for
those of you that have a “Kindle” e-reader.
I was able to borrow a Kindle from my sister and read the book.
Nothing you haven't heard before, but it summarizes in one
place the necessary steps to get your bees through the winter. It also explains the reasons for each step.
Here is what I gleaned from this book.
1)
The biggest cause of winter loss of hives is the
varroa mites and the viruses it spreads.
If you don’t have year round mite monitoring and control you are doomed
to have high winter losses.
2)
You must have strong colonies in the late
summer/early fall prior to the colony going into cluster. Bees should be heavily present on every frame
until cluster.
3)
He encouraged feeding in late summer and early
fall of both sugar AND POLLEN (or POLLEN SUBSTITUTE) to encourage raising of fat
winter bees. This is addition to fall feeding many beekeepers already do to top
off the colony’s winter stores.
4)
Re-queening in late summer helps with raising
large quantities of winter bees.
5)
Other minor aids such as screened bottom boards,
mouse guards, etc were discussed.
6)
He stated good beekeepers inspect their colonies
every two weeks.
So here we are getting ready to go into winter and I am
reviewing in my mind where I may have slipped up. I have treated for mites twice and plan to do
it once more. I can’t say all of my
colonies are “strong”. I did combine
several, but based on this book I should have combined several more. I did feed about half of my colonies (weaker
ones and new colonies), but not the stronger ones. Although I re-queened many colonies in late
summer I can’t say I was following his recommendation.
This year my late summer/ early fall preparation for winter
was better than any previous year and I am hoping for higher winter
survival. Next year I will add in the
feeding of pollen in the fall.

MITE COUNTS by beekeeper Fred
Today beekeepers Fred and Jon conducted mites counts on four (4) of Fred's hives. It was the first time for both of us. We had both watched two Randy Oliver demos on You Tube the night before; both sugar roll and alcohol wash methods. With two people the mite counting process took only about 5 minutes per hive. We used the alcohol wash method to check for mites. This method sacrifices ~300 bees per hive. I didn't want to kill the 300 bees, but felt that I needed to better understand the mite levels in my hives. The sugar roll method keeps the bees alive, but is not as accurate. Interestingly 3 of the 4 hives still had capped brood. None had eggs or uncapped brood. So the queen have transitioned to their period of not laying.
To run the mite check first you must pull a brood frame and bees. Very carefully check for the queen. If she gets in your 300 bee sample you just killed your hive. We did encounter a queen in one of the four frames we pulled and gently set her aside. Then you shake the bees from the frame into a plastic pan. Next you quickly scoop up a half cup of bees and pour them into the mite washing gadget.
The mite washer is two plastic cups that nestle together. The bottom of the inner cup is cut off. A piece of cheesecloth is wrapped around the bottom. A cup of alcohol is placed in bottom cup. The inner cup and cheesecloth are inserted into the outer cup. Pour in the bees. Put on the cap and begin shaking for a minimum of 30 seconds. The mites and bees are killed. The mites drop through the cheesecloth and collect in the bottom of the outer cup. See pictures. We poured the alcohol and mites into a tea strainer to make counting easier.
Mite washing gadget-I think the cups were Ziploc brand
Tea strainer showing 5 mites
As previously stated we checked 4 hives; 2 with Russian queens and 2 with Ankle Biter queens. The two Russian hives had 5 and 1 mites from the 300 bees samples or a 1.6% and 0.3% infestation rate. The Ankle Biter hives had 3 and 1 mites or 1% and 0.3% infestation rate.
I had treated all four hives twice. First time in mid-August with MAQS and later in mid-September with oxalic vapor. I plan to treat them once more in mid-October when all the brood will have emerged and the mites can no longer hide in capped cells.
I'm not sure if my infestation rates are good or bad. Over the past 10 years the recommended maximum infestation has been lowered. In the 1990's it started out at 20 per sample. but is now down to 1 to 3 per sample.

The Real Sting of Bee Theft
Investigators pursue a rash of honeybee crime during almond pollination
Don't dare try to steal from the bee detective. Jay "Rowdy" Freeman raises honeybees and rents them out during almond pollination. He's also on the felony investigations squad in Butte County, Calif., and stays hot on the trail of bee thieves.
Honeybees have long been a target for criminals during almond pollination, but the rate of theft has jumped due to fast money and easy pickings. Specifically, a honeybee shortage and an increase in pollination rental rates have combined to lure thieves.
California's 1.1 million acres of almonds translates to a $6 billion industry. However, the almond machine would come to a screeching halt without pollination and the Golden State doesn't have nearly enough honeybees to get the deed done. Every year, before the February to early March pollinations season, trucks from across the U.S.. make a pilgrimage west, packed with billions of honeybees. Roughly 1.8 million beehives are used during almond pollination - up to 90% of the available commercial hives in the U.S.
Hive rental rates quadrupled in a single decade, reaching an average $190 in 2016. Bee boxes are frequently placed in unsecured locations. Thieves case the hives and strike in the late night and early morning. Who's doing the stealing? "The majority of hives are stolen by beekeepers." Freeman explains. "They'll usually grab anywhere from 20 to 200 hives in one hit."
In a form of agricultural fratricide, beekeepers lacking bees for contracts steal from fellow keepers. For example, 100 stolen hives rented at $200 for a few weeks use means $20,000 in profit for no work or management. Commercial hives are often kept four to a pallet. Using flatbeds and forklifts, thieves load and drive several hours to another almond-producing area. They often take out the frames, place them in their own equipment, and drop the hives into their pollination contracts. Hive values can average $300 to $350, Freeman adds. Steal 200 pallets with four hives each and the math can bleed a beekeeper for $280,000: equipment, value of bees and queen and rental profit extrapolated for years afterward.
Gene Brandi, president of the American Beekeeping Federation, has been raising honeybees and pollinating almonds since the 1970s. "honeybee theft continues to occur because we're short on bees for almond pollination and colony prices are climbing . Bee rustlers exist and they rent the stolen beehives to unsuspecting almond growers. Legitimate keepers would never do it, but there are a few unscrupulous people in every industry, including the beekeeping industry, who are brazen enough to commit these crimes. There have even been a few people who set up chop-shops, grind off ID numbers and brands, and repaint the stolen hives."
Bee theft is low on the legal priority list. Several years ago, a thief caught stealing honeybees from Brandi and a dozen other keepers received a nine month suspended sentence and two years of probation. Although financial restitution was part of the sentence, only one victim received payment. FJ

HOMEMADE OXALIC ACID VAPORIZER by beekeeper Fred
After viewing a You-Tube video last year the idea of making a oxalic acid vaporizer has been in the back of my mind. My electric vaporizer works great, but I was thinking of doing a late February treatment and carting the heavy battery around in the deep snow didn't sound like an easy task. The video showed an easy to make propane powered vaporizer.
For about $40 I was able to buy all components to build the vaporizer. You might get by for less by buying the components at a big box store like Menard's or FleetFarm. The components are:
-6 inch length of 1 inch diameter black pipe threaded on both end
-4 inch length of 1/8 inch pipe (ID) threated on both ends
-Two caps for the pipe
-A piece of rubber to seal the upper cap.
-2 small hose clamps
-2 large hose clamps
-A low cost propane torch with piezeo-electric starter (I used a $20 unit from Menards)
-A 2 foot length of 1/8 inch thick steel strapping
-JB Weld epoxy
The most complex part of the assembly is drilling and tapping the 1 inch pipe to accept the 1/8 inch pipe. The JB Weld is applied to the lower cap threads and 1/8 inch pipe threads in order to seal these joints and prevent leakage of the oxalic acid vapors. Assembly is straight forward and by looking at the following pictures is self explanatory for almost any handyman/woman. The flame from the torch is pointed at the lower cap which holds the oxalic acid powder.
I plan to use a short length of rubber hose from the vaporizer to the hive. I will bring this vaporizer to the next club meeting.
Overall view. Top cap is not installed.
Steel strap can be forced into the ground and makes a good stand.
Oxalic vapor exiting the exhaust pipe.
You can see the blue flame impinging on the lower cap.
REMEMBER: Oxalic acid vapor is harmful to your lungs and eyes. Use a respirator or stay upwind.
