<p class="MsoNormal"><span style="mso-fareast-language:EN-US">Thanks everyone for your responses to this question. It’s an interesting point about the potential for some of the writing on the eggs to be water soluble. In such a case is something like anoxia
or high CO2 not preferable to freezing? And yes I guess I do know that the insides of eggs can be delicious to things like carpet beetle, and indeed I have seen some old evidence of such in our collection. We have 20k+ clutches going on 40k, and we are going
to move to a new building in a few years. In light of that I would like the most practical solution that minimises risk to the egg collection but still ensures we aren’t accidentally bringing a pest problem with us. But it sounds like the consensus is that
freezing would be ok, so long as we make sure everything is well sealed in plastic first?

<p class="MsoNormal"><span lang="EN-US">Agreeing with Stephen I’ve seen insects in egg collections. I agree strongly with freezing in a plastic container such that condensation does not occur directly on the egg when removed from freezer. While having no direct
evidence I suspect that some inks used for curatorial markings on eggs might be water soluble or be poorly bound to the egg surface and condensation poses a risk of information loss.<o:p></o:p></span></p>

<p class="xmsonormal">Hello all,<o:p></o:p></p>
<p class="xmsonormal"> <o:p></o:p></p>
<p class="xmsonormal">I am wondering if any of you have thoughts on freezing egg collections for pest control? I imagine that it is probably ok, but then I wonder if there could be problems to the shell structure. Note I realise that there is not much for museum
pests to eat in a blown egg, but there are lots of places for them to hide in and around the their housing. As usual, any thoughts or feedback would be very appreciated!
