An anonymous entomologist and PCO who reads the blog has clarified for me the issues around Gentrol (an Insect Growth Regulator commonly used against bed bugs, by PCOs: IGRs are supposed to halt growth, which should cut off reproduction).
But my source tells me this:
In recent research, the results seem to indicate that the
use of Gentrol is at best not producing the
expected positive results in regard to overall
bed bug reduction. In fact in this study it seems
that the use may result in a long term increase.
But again this is one study and the unexpected
outcome itself still needs to be studied.
It hadn’t occurred to me that Gentrol could be not just ineffective, but might also make your bed bug problems worse. Still, the jury is still out, and we need more information.
I would not panic if your PCO uses Gentrol, but I also would not start lobbying for it if they don’t.
