We found two live bed bugs in the books treated with NUVAN when we unpacked them/vacuumed -- they were hiding in a tight spine hollow. We've since put them in a -20 freezer for treatment. We are planning to do 7 days in the freezer, 6 days out, and another 7 days in the freezer. Would anyone recommend a different cycle/combo for a -20 freezer? And if we used a 0 freezer, what cycle would you recommend? That 7/6/7 cycle seemed to work on the batch of books we froze last time but they also weren't as heavily infested. We did not find any evidence of dead bed bugs either. Thanks again, Stephanie __________________________________ Stephanie Lamson Preservation Librarian University of Washington Libraries salam...@u.washington.edu On Fri, 14 Sep 2012, Louis Sorkin wrote: > This is a message from the Museumpests List. > To post to this list send it as an email to pestlist@museumpests.net > To unsubscribe please look at the footer of this email. > ----------------------------------------------------------- > > There was a recent report by Wang, Lü, Xu. 2012. in J.
