Sorry, Neil
Looking at some of my pin specimens. Carpet beetle larva and Mole cricket.
Used MPE-65 at about two x.

They have cost me a lot over the years. A collection of hackles and feathers for fly tying, a Cornell drawer with a series of dragonflies, and about a hundred papered, reared Saterniids worth a few hundred dollars. Not to mention the constant watch over the little I have left. Time for the minus 20 or so F. freezer. I have a theory about predicting the chance of a specimen being damaged by a Dermestid. The chance of damage is proportionately increased by the rarity and value of the specimen.

That looks like a very good use for that lens, horrible little larval critters, well done. My threat of stealing it worked then

I have only small remnants left of a once very large collection. Those are kept in air tight boxes and they seem to be ok. Using napthalene is limited, since the darn stuff evaporates and I wonder what breathing it would do over the long term.

Napthalene is mothballs, if I remember correctly. Repels but not fatal. PDB, paradichlorobenzine, or moth Chrystal's kills. Both stink, and they both sublime. My boxes were made by me, they are tightly fit, I thought. The first instar is minute. They get in and do damage, but cannot get out. When I donated the bulk of mine the first thing they did was super freeze them before adding to general collection. SOP, I was told.
