We searched online first for more info on how to use sulfur in the smoker. Like Iddee said, light up your smoker, good thick smoke, put a tablespoon of sulfur in, close it up. Go to the hive and smoke the entrance real good like for 4-5 minutes. I put a old towel around the entrance because it helped direct more of the sulfur smoke straight into the entrance, it was a little windy. I did three sulfur smokes in one afternoon. By that evening I didn't think it had any effect on the bees. I left the hive alone overnight. By morning the entrance was blocked by dead bees. However, I knocked on the hive and there was still a definate buzz. I got our shop vac and vacuumed out the entrance... then I took the lid off and vacuum as many live bees as I could get out. I got them all. Mission accomplished
Then I got my grandsons toy trumpet and very slowly walked by the other hives playing Taps, pulling the shopvac behind me...
Seems this recipe is good for a hive that is one deep or maybe 2 deeps of bees, no more than that. My hive was 5 boxes tall and I think the sulfur only got to the bees on the bottom portion of the hive.
