This is from their literature:

Bee hives were sprayed with full concentrate BZB nutrients made of amino acids and salts. Varroa mite counts were taken at 1- and 24-hour intervals post-spray to assess the efficacy of Terra Vera's technology in promoting bee health while creating an inhospitable environment to the Varroa mites and other pests.

The Results
After 1 hour post-spray, 100% of bees were alive while 99% of Varroa mites were no longer on the bees. The same efficacy was observed 24 hours post Terra Vera application.

Conclusion
The results of spraying full concentrate, activated BZB nutrients on honey bee hives showed high efficacy postspray that was maintained over several hours.
