"BeeVital HiveClean? activates the purification of bee colonies. Honeybees will be regenerated by natural means and will produce best quality honey."
Sorry, but it sounds like meaningless drivel to me... What do you "activate"? What is "purification of bee colonies"? Is it a purgative? Laxitive? Does it give them the runs? How are the honey bees "regenerated"? What does it mean to "regenerate" a honey bee? My bees already produce the "best quality honey". How is this product going to improve that?
"activates the natural cleaning instinct of the bees" Bee already have natural cleaning instincts...
"...microscopic droplets to adhere to the fine hair of the bees. Through social contact and the natural instinct of purification, the product is distributed evenly to all other bees and ensures, that the cells containing dead larvae are thoroughly cleaned by the activated bees. These larvae and all other foreign objects as well as dirt particles are consequently removed from the bee hive."
So this makes them all feel dirty and that motivates them to clean out dead larvae that they were otherwise going to leave there? I'm sorry, but bees already do all these things without anyone spraying anything on them...
