RE: [pestlist] Bed bugs treated with diatomaceous earth
This is a message from the Museumpests.net List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe look at the footer of this email. --- Hello Jessica, I can’t answer most of your questions but diatomaceous earth is used for passive treatment of bed bugs and other insects. They physically have to crawl across the sediment for it to have effect, it scratches their undersides and ends up killing them. Exterminators will place it around trim, in corners, electrical outlets, anywhere that they may be hiding. Generally in treatment an insecticide or other poisonous substance is used as a more active treatment so you may want to research the types that were used at the time of treatment in your area for health and safety concern for staff. There is food grade diatomaceous earth so it isn’t in and of itself necessarily harmful to you beyond irritation to eyes or lungs even if this particular usage it isn’t food grade. The issue would be more if it’s ground into the collections or related concerns. Typical ‘waiting them out’ treatment can be up to two years. If they’re been sealed or isolated for the 10+ years since treatment it’s likely that there isn’t a concern but I would be personally very concerned as you sound like you might be. No good story ever started with, “So I found this bed bug……”.

If it is, they tend to like a number of different textile type items but have a tendency towards animal hair/fur, clothing, carpets/rugs, and that type of material. Check your surrounding environment for similar materials and see if you have any larvae or more full grown moths. Depending on what you find depends on what you do. Anywhere from dry cleaning to large scale freezing. Keep the humidity under control, regular inspection, good house keeping policies, sealing of items (if appropriate), and closing up entry points will deter further issues. Sticky and pheromone traps are handy for keeping an eye on the situation. It might be something else or could have come in on someone, lets hope!

RE: [pestlist] "Forest Debris" and Possible Pests
This is a message from the Museumpests.net List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe look at the footer of this email. --- Erika, Ah! My concerns would be about the same as yours: potential for pests (new and existing even with past treatment), dust, and additionally people. I don't know how much the charcoal would be of interest to pests but the unburnt/partially burnt items may. The image shows well burned items but there may be some parts that still have enough to be of interest to pests. The silk is the same concern as if you had silk items in your collection in my opinion, monitor and be careful. This would honestly be my least concern for this piece. The dust from the charcoal would worry me. Disaster response literature or those that have participated in a response effort for a fire will note how charcoal dust and soot gets EVERYWHERE. As it is so fine it can get ingrained into just about anything very easily. Granted this will be much more controlled than the dust/soot from a fire but I feel it would travel easily. That leads to my last point of people. People will touch the charcoal. I want to say especially children but as I'm sure everyone has seen adults are just as bad. After they touch the charcoal they will do their best effort to touch everything within reach, especially if its collection items. This would be my biggest concern. Would it be possible to have the charcoal and burnt silk in a Plexiglas box? Off the top of my head, a base of Plexiglas, the artist or staff arrange the charcoal and burnt silk on the base and then a Plexiglas lid is placed over top, possibly within a shallow recess so the lid can't easily slide off? While this isn't impenetrable it would certainly drastically reduce any concerns and would minimally affect the aesthetic of the piece. Good luck!

To post to this list send it as an email to pestlist@museumpests.net<mailto:pestlist@museumpests.net> To unsubscribe look at the footer of this email. --- Hello once again! No beetle questions this time! An artist has proposed an installation that is going to include "forest fire debris" (please see attached image). The artist has described said "debris" as such: "...the 'debris' is more or less charcoal and silk, piled in a line about 6" high directly beneath the photo. It is the charcoal remains of the forest that appears in the photo, so it is essential to the concept of the piece. Some of the charcoal retains the shape of pine needles, cones, bark, branches or wood. It is fragile and can be crushed by hand. The brown bits you see in the picture are charred pieces of silk from the bottom edge of the photo. There are no leaves or wood chips. The charcoal bits have been re-burned and subjected to multiple freeze-thaw cycles. The material was screened after cooling down to remove ash and fine dust. The reality is that both the charcoal and silk are very fragile and can be pulverized in handling as well as shipping which can result in dust." Obviously there are many concerns about this installation. The artist claims to have done freeze-thaw cycles but how much would this actually help in regards to keeping pests away. Certainly it could rid the "debris" of any bugs that might be in there at present...but what about prevention? We have a prohibited items list that we use for flower arrangements and pine cones, bark, branches and wood (unless it has been treated) are prohibited. But I am not so sure about these items after they have been burned. This work has mainly been in galleries in the past...and I think this is the first time it is coming into a museum so I don't have any institutions that I can contact to see what they had did during install and the duration of the exhibition. I am hoping that we could make this work, but no matter how I look at it this install seems like it can't happen. Does anyone have any experience with dealing with piles of charcoal? Are there any pests that would be attracted to this material, would they be the same types that are attracted to wood and plant matter even though this material has been burned down to charcoal? Obviously the dust is also a concern because of our HVAC system...but that is a w

I don't allow any kind of food on this level of the building, nor any drinks outside of water in resealable bottles and then only in designated areas with restrictions. Most of the time there's no one else on this level of the building and if there is I'd likely notice them bringing in food or other drinks. I haven't seen any fruit flies in the collections storage areas (woo!). There are exhaust vents in my work area and in the washroom. The washroom vent empties out into a crawl space under part of the building and I'm not sure where my work area vent goes but potentially the same spot. Some of the fruit flies have been getting stuck in the sticky trap in the washroom which is located by the door jam. I haven't noticed any fruit flies in other traps so I'm thinking they may be coming from there and potentially from the crawl space through the vent, though why they'd be in there I don't know. The main level of the building does have food friendly areas such as offices and a food service area for events but there doesn't seem to be an issue up there and I don't know how they would continually be getting down here as there is always at least one closed door to get, though generally more. It's a scent free workplace so it's not like I'm wearing eau de pourriture fruits perfume down here! Any thoughts?

RE: [pestlist] What kind of you larvae is this?
Hello Oberli, It looks like it could be a black carpet beetle larvae, though it’s quite pale in colour from what I’d expect; however, this could be your answer as you say you’ve found previous evidence of carpet beetles. Typically black carpet beetles eat animal products so they’re probably not interested in your artificial petals if they are synthetic but if they’re made with animal products or some of the packaging is they may be after that. A pest expert can probably weigh in but I thought I’d throw in my two cents nickels.
