"C02 gun for varroa
by Gina on Feb 22, 2024
This is the 3rd c02 gun. This is the only 1 that has worked. I was told 2 squirts, bees knocked out 30 seconds. Well, they were moving so I got trigger happy so 2 more squirts. Bees were out a solid minute, n minute 1/2. They finally woke up, alive and moving around. I scooped them off the concrete block and put in hive. I'm so happy I have 1 that works and no killing bees in the process."
