2022 Citizen science to calculate Varroa economic thresholds.

BC-TTP will need the participation of beekeepers in British Columbia.


When?  March 31, 2022- March 1, 2023

How? Beekeepers will be asked to join a webinar or watch a video on how to upload information to three online surveys, including:

-Region of BC where bees are kept

– Mite levels in the spring (March to June) and fall (September to November)

-Method used to calculate mite levels (i.e. alcohol wash, sticky papers, or icing sugar)

-Colony strength in the spring (March to June) and fall (September to November)

-If a treatment was used to control mites (e.g. thymol, oxalic acid, Apivar®)

-Honey yield (March 2023)

-Overwinter colony mortality (March 2023)

Who? Beekeepers in British Columbia with at least 1 honey bee colony.

Important Note: All the information will be kept private. The data will be used to calculate Varroa Economic Thresholds (ET) in different regions of BC.


  1. See the video below for instructions on monitoring for mites.
  2. Send us an email to confirm your participation at
  3. Complete your monitoring and submit your data. There are two ways you can send the data

    a) By filling out the online surveys for:

    Spring Survey 2022

    Fall Survey 2022

    Spring Survey 2023


    b) Or, download the excel file Survey Citizen Science, save a copy and fill out the forms then email to 

  4. We will post updates on the project on this page or follow us on Facebook, Instagram or Twitter @bc_ttp.
  5. If you’d like to share your experience or progress (optional),  use the hashtag #BCTTPvarroa to post your pics of varroa monitoring.
  6. Share your feedback, questions or comments with us at
  7. Share the info with other beekeepers, associations and local clubs.
