It may be, but alcohol is no more effective than cracking the little bug(ger)s between your teeth. Nor does setting the bed legs in coffee cans of kerosene work well. Obviously, in hotels which change linens daily (and use soap/detergent), the problem (and the bedbugs) would lurk in bedding (spreads, mattresses, pillows, etc.) for which effective treatment involves an insecticide. I'm sure that some of the organics (Pyrethiums?) would work, but that still leaves wool carpet or even some room furniture as temporary harboring material (although I suspect that bed bugs have a short lives not extending beyond a single egg laying cycle, without human contact/nourishment).

Since several sources suggest that guest luggage is the most suspect transport medium, do you want the TSA to spray bags?
