<p class="MsoNormal">I managed dermestid colonies in North Carolina both in a museum and in buildings outside the museum. Temperature and humidity within the museum were fairly stable, but there were high fluctuations in the buildings outside the museum. Outside
the museum, we maintained dermestids at temperatures between 7 - 43 deg C (45 - 110 deg F) and a relative humidity of 5 - 90% RH. When the humidity spiked in late summer to early fall, we added moisture by only wetting paper towels in a tray not touching the
specimens or substrate. <o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">I experienced mold outbreaks with high humidity, and this was a time when I saw adult dermestid beetles fly. I have also witnessed flying adults within the museum when dermestids within a single tank were overpopulated. Dermestid tanks
with flying adults were never opened in the museum until no flying beetles were present. Both flying adults and escaping dermestids can be managed with container/building modifications and protocols when adding/removing specimens.<o:p></o:p></p>

<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Skeletons coming out of dermestids were frozen for one week at the minimum. Each skeleton was then soaked in 70% ethanol, rinsed with water, dried, and then frozen one more time before going to the collections. This ensured that all life
stages of dermestids did not survive before going to the collection. Below are a few comparisons we experienced.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">Steve also had specifics on feeding and management of the colony to keep it healthy. Some interesting observations he made include: they prefer dried meat (although they will
eat fresh, also fresh meat can develop mold or rot); manage the food so that there is little left over; remove excess casts skins to help control mites.<o:p></o:p></p>
<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><br>
As for location for the colony – it is safest to have it in a separate building – if that is a possibility. Freeze the cleaned specimens before you bring them into the museum to reduce the likelihood of carrying the dermestids into collections that could be
damaged. That said, if there is no possibility of an external facility for the colony, you can have one in the building, even close to the collection
<u>if the colony is well managed and monitored. </u> There are a number of ways to do this. At the Science Museum of Minnesota – we had a colony that was not only adjacent to the biology lab, but visible to the public. We took the following precautions: The
room had a small, dedicated HVAC (I have seen dermestids live inside of vents and move from space to space through the ducts). The room was incredibly well sealed, with gasketing and door sweeps around the one door. The window into the gallery was very well
sealed. There were screens over the HVAC Vent. The room contained shelving that was easily cleaned. The colony was in aquariums with screen covers that were well sealed. There was a chest freezer for both storage of specimens to be cleaned and pest control.
We kept sticky traps around the aquarium and used tacky floor pads. Also, the room was kept very clean. Please let me know if you want to talk more off list.

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto"><span lang="EN-AU">I was wondering if any of you could provide insight into Dermestes maculatus, the hide beetle. I just read a paper (Strang & Jacobs 2019) stating that D. maculatus
was not able to live outside the colony (at the Smithsonian) due to ‘humidity and other requirements’, but sadly there wasn’t a citation. Likewise, I have seen dermestid colonies housed inside collection buildings (such as at the Field Museum), apparently
with no threat to the skin collections also housed nearby. I have not been able to pin point down why hide beetles wouldn’t be a threat to museum specimens, but I would love to hear any experiences with them or thoughts on what their infestation risk is to
collections. They certainly can eat a lot when they get going! I would love it if I didn’t have to feel a slight sense of existential dread every time I put a newly created skeleton specimen away (thoroughly cleaned and decontaminated, but still…).</span><o:p></o:p></p>
