I use the inverted hive lid with an empty deep on top to inspect and remove frames from the hive I am working on. The lid with an empty brood box is also handy for setting brood boxes on as you go through a hive. The empty keeps the heavy box elevated so less strain on the back. I also tend to set hive tool, smoker and so forth on the next hive.
I have been wondering for some time whether this is a bad idea because the banging, thumping and clanging could set off alarm pheromones. The colony that you haven't even gotten to, yet, could already be on alert before you even approach them.
I have also thought about the ground shaking thud that I create when I remove the cinderblock, brick or rock that is on top of the hive lid.(Yes, I throw them off. Especially the cinderblock.) To the bees that probably feels threatening and the alarm pheromones could be triggered.
Does anyone else have any thoughts regarding this theory?
Correct or not, a cart or stand would be an excellent back saving addition to a beekeeper's tools. Next year's Christmas wish list?
