[Nhcoll-l] [EXTERN] Pest extermination with really big objects

[Dirk Neumann]

Hi Adrian,

have you considered anoxic treatment in an Nitrogen bubble? Probably this service is available in Sweden as well?

Hope this helps
Dirk

Hello!
We at the Swedish Museum of Natural History are moving material, mostly bones and mounted mammals, from one external storage facility to another. The facility that we are evacuating is riddled with pests, mainly the dermestid Trogoderma angustum, so everything has to undergo some sort of pest managing procedure before installation at the new place.
Unfortunately, a few bone objects are too big to fit in available freezing containers or our own walk-in freezers, and we are struggling to find a way to kill of pests that are sure to reside in the objects. The biggest object is a sperm whale skull measuring 275 * 590 cm at the base with a height of 215 cm.
We have tried to find businesses that might dispose of huge freezers without any luck, and we have failed to find clever ways of tilting the objects in to the freezing containers.
Does anyone have any ideas here? All thoughts are welcome as we really don´t know what to do at this point. If you have worked with fumigation, we are interested in what compounds where used and if you were happy with the results.
Best regards,
Adrian Lenninger
