> it would appear that bottom board flash treatments would therefore be 
the most effective method of application.

Originally liquid formic was just shot in on the bottom board with a 
syringe or like device (such as a sheep drenching tool). The switch was 
then made to soaked pads, news paper, etc slid in. These slowed 
release.  None had the efficacy which we found later by placing the pad 
on the top bars, they were however very good for dropping queens.
