Don’t Believe Everything on the Internet. Finding the facts!

Thursday, 8 October 2026

With so much information at our fingertips, it is sometimes difficult to know which sources are credible.  As a beekeeper how do you avoid the fake news and for real information about the beekeeping industry, where do you turn?  In order to help beekeepers get to the bottom of what is what, the current blog talks statistics and information and where you should go to find out the truth about our industry.

Don’t Believe Everything on the Internet.  Finding the facts!

Beekeepers know that best management practice dictates that records should be kept meticulously and maintained indefinitely.  This valuable information reveals trends and patterns over time.  This then will become a great resource in your own beekeeping and a reference point for comparison.  You will record your own winter losses, for example, and then compare that data to industry stats.  This leads to the question of where to get industry data on winter losses amongst other information.

National groups, like the Canadian Association of Professional Apiculturists (CAPA), are great sources of information.  Every year CAPA produces a document entitled, “Report on Honey Bee Winter Losses in Canada.” This is a coordinated honey bee winter losses and disease management report, as stated by the group.  These reports have been produced in a standardized format since 2007 and have become heavily relied on by both beekeepers and industry decision makers.  The data is collected from beekeepers by provincial apiculturists annually and then collated by a CAPA committee.  ATTTA has participated in the committee which produces the report.  The trustworthiness of the information, as it is data from beekeepers, collected by provincial apiculturist and organized by professionals like tech transfer specialists, is high.  If you are not using this data, familiarize yourself with these most useful reports: https://capabees.com/capa-statement-on-honey-bees/ .

Federal government is another credible source of information on the honey bee industry.  There are three important groups that deal with the beekeeping industry and have information and data available to beekeepers.  The Canadian Food Inspection Agency protects the Canadian consumer and beekeepers from honey fraud and adulteration, especially on imports.  Additionally, this agency enforces the rules under the Animal Health Act to protect our honey bees from pests and diseases entering from outside of Canada.  So, if you have a question about packages of bees imported from the USA, as one example, a look on the CFIA online resources will provide direct information.  There you will find stated, “Currently, the importation of honey bee packages from the U.S. is not permitted.” 

A second national source of information is the former Pest Management Regulatory Agency, currently rebranded as Health Canada’s Pesticide Management Directorate (PMD). Amongst other things, PMD approves miticides for use by Canadian Beekeepers.  If information about label instructions is required, then the PMD online directory will have all label information for all registered products. A good use of this directory could be if you are unfamiliar with the use of slow-release glycerine pads for Varroa control, you can find credible information here: https://pr-rp.hc-sc.gc.ca/ls-re/index-eng.php . 

At the provincial government level, there is also good availability of information and data.  Provincial apiculturists collect data as part of the registration process and through interactions with beekeepers.  The best example of providing data for beekeepers in our region is the Nova Scotia Open Data Portal.  This service is established to make government data easier to access for individuals, businesses and researchers.  There are useful data on honey bee imports into the province which can be view through this link: https://data.novascotia.ca/ . Industry data and information is available from other provincial departments, such as PEI industry statistics shown in the figure.


When looking for data, ensure that it is from a credible source.  Also understand that summative data will, by its nature, be historic.  That means, generally, that we will have annual 2026 data in 2027 or later. The winter loss survey is an example of this as we still do not have the final report for the winter of 2025 – 2026. 

Many claims and information sources found online are questionable.  Beekeepers have to make hundreds of decisions for their operations.  All of these decisions need information to ensure they are solid and will support the success of your business.  Filtering online slop to distill out only the verified facts, checking against multiple independent and trustworthy professional sources is essential.

Review of new Varroa Management tools: Part 2 of 2

Thursday, 1 October 2026

To complete the review of new Varroa mite management tools recently made available to Canadian beekeepers, this week’s blog will discuss oxalic acid based miticides.  Oxalic acid is already a much relied on Varroa Management tool but this season has seen two new options for the delivery of this organic-acid based acaricide.  Having gained some experience of these new options, through both hands-on and anecdotal reports from other beekeepers, we summarize some aspects of their use in this blog.

Review of new Varroa Management tools: Part 2 of 2

Oxalic acid treatments have been proven, through both research1 and practical reports by beekeepers, as effective in controlling Varroa mites.  This is especially true when used as part of an Integrated Pest Management (IPM) strategy.  There are two new formulations available to Canadian beekeepers for the 2026 season, one being a “homemade” formulation and the second is a commercial strip.  

The 2026 re-registration of oxalic acid dihydrate includes three application methods.  These are the solution (or drizzle) method, vaporizer method and the glycerine strip method.  The glycerine strip method is new for Canadian beekeepers.  There are clear preparation instructions available on the Pesticide Regulatory Directory website: https://pr-rp.hc-sc.gc.ca/1_1/view_label?p_ukid=439350856 . For most beekeepers, making miticide strips is not a practical option.  There are economic benefits if the strips are made on a large scale.  This saving must be balance against the additional complexity of ensuring the strips provide a correct dose of oxalic acid.  There have been some reports from beekeepers of low efficacy which, it was assumed, was due to an improper dose.  With all pesticide application, follow the label directions but with creating oxalic acid glycerine strips, carefully follow the PRA instructions.  

VarroxSan™ is a product which has beekeepers buzzing and has been newly registered for the 2026 beekeeping season.  This treatment is also based on oxalic acid dihydrate but is a commercially prepared product from Vita Bee Health. This has been used by a number of beekeepers in the Maritimes this season and reports are positive.  The flexibility of this treatment, ability to be used with honey supers present, is one great advantage of VarroxSan. 

Treatment costs are somewhat variable, but a pack of 60 strips is between $90 and $100 from beekeeping suppliers.  So each strip is $1.65 at the higher prices.  The application is easy and straightforward.  The long strips fold over frames and are applied at a rate of one strip per 2.5 frames of bees.  This is to a maximum of 4 strips per brood chamber and six strips per hive.  Maximum cost for a strong double colony would be just under $10.  

Once in place the area behind the strip is lost to brood production and the opposite face may be as well.  There are a few reports of brood dying behind the strips, early in the treatment period.  This loss of brood was initially mistaken for disease but after some discussion this was determined to be due to the physical presence of the strip. The bees seem tolerant of the strips otherwise but a couple of incidences of the bees chewing the strips were reported.

At the end of the treatment period the condition of the strips is varied.  There have been some cases of the bees removing the strips which have been found in front of the hive.  Chewing of strips has been reported (as shown in the figure).  A large number of strips became saturated with moisture or described as “mushy”.  Although unlikely to have any reduced efficacy, these “mushy” strips can be more difficult to remove.

As an early spring treatment, when honey bee populations are growing, brood space is crucial.  At this time, the loss of space behind the strips is a consideration.  As a mid to late season treatment, this will not be as important.  Using the VarroxSan strips, while honey supers are in place is an excellent option to prevent the growth of mite populations.  This treatment will allow beekeepers to determine the need for and apply further treatments at the point when honey supers are removed.  This will help keep the Varroa mite populations under the 1% infestation threshold!

In summary, oxalic acid is a reliable tool for controlling Varroa mites which now has two additional options for its application.  The glycerine strip method has added complexity and beekeepers are advised to take care when preparing and applying oxalic acid with this type of method.  Monitoring when using all treatments is recommended but with the glycerine strip method it is especially important.  The VarroxSan strips, unlike the glycerine method, can be applied with honey supers.  The impact on honey production, if any, is unknown but as more information accumulates it will be revealed.

Additional monitoring to determine the Varroa populations at the time of honey harvest is still necessary.  At this point a more aggressive treatment may be required to ensure winter bees have an opportunity for optimal longevity and winter survival in a low Varroa/virus environment.
