Using the oxalic acid dribble method for varroa mite control.
Oxalic acid is an exciting new tool in varroa mite management. The two most common application methods of oxalic acid are sublimation (vaporization), and the dribble method. Of the two of these, we prefer the oxalic acid dribble method in many situations.
Many people are rushing to buy oxalic acid sublimation tools (vaporizers) to take advantage of the ease of use and the minimal intrusion. These tools are great for times when the temperatures are cold, and opening the hive can be detrimental to colony health.
There exists, however, a much quicker and less expensive method of application. We believe the intimidation factor is one of the main things preventing widespread adoption of the dribble method. We hope that the three videos in the playlist above show how easy this method of mite control truly is.
Please keep in mind that no matter which method you choose oxalic acid has some limitations. First, oxalic acid does not kill mites that are reproducing in capped brood. This means that it is most effective when there is no capped brood in the colony. Second, oxalic acid in not approved for use with honey supers on.
