You received good advice from Ellen about the particulars of freezing and from Pam about seeking help from local universities. I also wanted to remind people on this list about the www.museumpests.net resource and its PestList e-mail list which are both meant to provide resources for exactly these kinds of issues. You can register for the PestList by visiting www.museumpest.net and following the instructions there.

They have been in a freezor for over two weeks. The previous collections manager said that they should now be taken out for two weeks to allow any existing eggs to hatch (because they are not affected by the cold) and then the objects put back in the freezor for two weeks to kill newly hatched bugs. Then if we felt it was necessary repeat the process again. The current collections manager said that where she worked before they only froze objects for one week and that was it and that was supposed to kill all the bugs and any eggs. What is the correct way for doing this? Thank you.
