<div dir="ltr">Dear Adrian, <div><br></div><div>Have you checked the option of anoxia - in the old facility or the new? Although this is indeed a difficult situation, creating giant anoxia "bubbles" could be more feasible in a case where all of the objects need to move somewhere, but haven't yet entered that place. Anoxia bubbles can be tailored to size, with temporary racks of wood or metal stationed inside so that even very large objects can be treated. For us, the problem lay in not being able to move a collection into a bubble for lack of space and the size of the collection within an existing storage place. In your case, you are already planning to move, so could it be possible to move first into a bubble and only then into the final storage? </div><div><br></div><div>Since we can't move all of our collections into anoxia, we had to fumigate with pyrethroids (because pyrethroids are less toxic to mammals, with some exceptions (e.g., cats). The trouble with fumigation of large collections in building spaces lies mainly in these spaces not being 100% sealed and the collections often being within packs or enclosures or stacks (herbarium stacks, for example) in various ways, so that fumigation may help, but may not be 100% effective. Anoxia would be much more effective - but requires the right kind of setup. Moving collections could actually provide the circumstances for setting up an intermediary stage of anoxia. </div><div><br></div><div>Best, </div><div><br></div><div>Gali </div><div><br></div><div><br></div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Mon, Sep 8, 2025 at 3:21 PM Adrian Lenninger <<a href="mailto:Adrian.Lenninger@nrm.se">Adrian.Lenninger@nrm.se</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg-8078667042398932206">

<p class="MsoNormal" style="margin-bottom:10pt;line-height:115%"><span lang="EN-US">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.<u></u><u></u></span></p>
<p class="MsoNormal" style="margin-bottom:10pt;line-height:115%"><span lang="EN-US">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.
<u></u><u></u></span></p>
<p class="MsoNormal" style="margin-bottom:10pt;line-height:115%"><span lang="EN-US">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.<u></u><u></u></span></p>
<p class="MsoNormal" style="margin-bottom:10pt;line-height:115%"><span lang="EN-US">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.<u></u><u></u></span></p>
