First Annual Mite-A-Thon, Sept. 9 – Sept. 16, 2017

By: The Bee Informed Partnership

The Bee Informed Partnership is proud to be a supporter of the first annual Mite-A-Thon that will take place Saturday, September 9 to Saturday, September 16, 2017 and we invite you to participate!

The Mite-A-Thon is a national effort to collect mite infestation data and to visualize varroa infestations in honey bee colonies across North America within a one week window. All beekeepers are asked to participate, creating a rich distribution of sampling sites in Canada, the United States, and Mexico. As beekeepers upload their varroa monitoring data to, you will be able to see Varroa levels in your region on this dynamic site! Click on it frequently to see the heat maps and view infestation levels during this critical beekeeping month.


  1. Raise awareness about honey bee colony varroa infestations in North America through effective monitoring methods.
  2. Management strategies will be made available for discussion within bee organizations utilizing Mite-A-Thon partner developed information and outreach materials.

PARTICIPANTS: All beekeepers are welcome to participate – we need bee associations to help lead this effort!

DATA COLLECTION: Participants will monitor the level of mites (number of mites per 100 bees) using a standardized protocol utilizing two common methods of assessment (powdered sugar roll or alcohol wash) and then enter data, including location, total number of hives, number of hives tested, local habitat, and the number of Varroa mites counted from each hive. The published information will not identify individual participants.

COST: There is no cost. You can create your own test materials or kits can be purchased online.
