I am surprised that the US is still using clearer boards (fume boards), and something on them that apparently smells like vomit. I can only remember using carbolic or benzaldehyde here. So why are some bods using something that smells like vomit? Is it regarded as character building? And the option you propose??? Escape boards on a large scale are less than adequate, abandonment is dependent on a lot of factors, and blowers can be hard on bees. Not aware of other choices?
