Is Boric acid powder for bed bugs?

I am a professional in pest management and the subject recently came up in a discussion with a number of others in the industry as well as academics who are researching this area. The general recommendation is that diatomaceous earth or silica gel work better than boric acid and are considered safer for this application. Boric acid is a great product and is used as an active ingredient in control of roaches and ants, but not as good for bed bugs...
