<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I have been working at the Harvard MCZ for 25 years now, Collection Manager for the past 14 years….anyway, after all of this time maintaining our beetle colony
and working in an old historical collection with specimens that date back to the 1830’s and old wooden cabinets almost that old
</span><span style="font-size:11.0pt;font-family:Wingdings;color:#1F497D">J</span><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"> (all new steel cabinets now), I have learned a few things about carrion beetle pests. While the
cigar beetles may eat plant material, what I have noticed about our dermestid colony is that they DO NOT like silicone sealant at all. We have our colonies in old bathtubs up on cinder blocks (waist high) and I had a carpenter custom make wooden framed screened
lids. We sealed the inside of the lid were it meets the screen with clear silicone sealant (like bathtub caulking) and low and behold, they have never chewed their way through the sealant, even though they can burrow through the wood next to it. I have a
feeling that they dislike the smell/taste of what smells like acetic acid (vinegar smell) in the sealant (probably used as a solvent and quick-drying agent?). I guess my point is….if you clean out the cases, remove all drawers, HEPA Vac the inside of the
cases and drawers, then use the caulking bead to seal cracks and seams……it may help a lot, especially if you do not have the funds to buy new steel cases. You can also buy new weather stripping (several types of material) at a Home Depot to reseal around
the cabinet drawer.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">Additionally, we had one area of our collection that constantly had outbreaks of odd and ham beetles (deer skeletal collection). We tried freezing each specimen
drawer (sealed in a large zip or garbage bag) that was infested several times, adding moth balls to the sealed drawers , etc…nothing worked, the pests always came back. I finally ended up just putting each skeleton in its own (4mil, white block zip bag from
Uline) Ziploc bag and then labeled it nicely with self-adhesive labels. This prevented future infestations and if the skeletons were already infested, the beetles could not escape the Ziploc bag and thus finally died out, preventing infestation into other
drawers of specimens. I’m not sure if you can slide the herbarium sheets/specimens into a zip bag…..but it would prevent further infestation. If you think sealing the specimens in zips may cause humidity problems, you can always add Drierite (spelling? Calcium
carbonate) or those little sacs that have absorbent material in them (silicone?).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I hope this helps even a little bit, good luck, Judy<o:p></o:p></span></p>
