The samples they brought me have numerous cast larval skins – definitely dermestid, I suspect Anthrenus sp.. The little darlings have damaged the felt pads (stops). I sent my friends back to their pipe organ with sticky traps to see if the infestation is active, and to see if we can get a better identification. Has anyone encountered this situation in an organ?

Casings pictured above were removed from the basement ceiling; they are attached in groups of three or four at various intervals throughout the basement.

Her museum recently received a large shipment of paintings for an exhibition – about 70 acrylic paintings on canvas. They have unpacked about one third of them and found signs of infestation, dead beetles (unidentified at this point), larval casings, dust, etc. Most concerning is some of the stretchers have exit holes with powder post beetles caught in tape. The powder post beetles have been positively identified. Nothing live has been found to date. Staff are examining the paintings and vacuuming the backs with HEPA filtration.

[pestlist] killing bugs and leaving a beautiful corpse

I noticed that a squirt of Windex incapacitates them temporarily but does not kill them, so I dropped a small bit of cotton wet with full-strength ammonium hydroxide into the jar with a recently caught one, and it died quite quickly. I am not, however, looking forward to opening the jar. Is there some other common but deadly substance (other than RAID) that would make a quick kill? Based on my Windex experience, I suggest it when you are trying to catch insects without squashing them. It may work on flying ones as well as crawling ones.

Re: [pestlist] Defrosting

To post to this list send it as an email to pestlist@museumpests.net To unsubscribe please look at the footer of this email. --- I believe that many institutions keep the things they've frozen in the bags. Given the use of collections, there may be no good reason to go through the time and trouble of handling things, and the plastic bags will keep bugs out as well as dust and gaseous pollutants, at least for a while. I know that we chronic worriers (conservators, registrars, and collection managers) are always looking for potential damage, but there are a lot of things that aren't as bad as we might think. RH issues often seem troublesome, but when a hygroscopic item takes up most of the space in a plastic bag, the controlling moisture is the moisture content of the item, not the RH of the air. Likewise, I think, with the possibility of thermal shock; it's a highly unlikely problem. It would help us if we could get reassurance about potential problems that , so far, turn out OK. Here's what I think we should do: make a concerted effort to report any damage we have observed on this list, along with reports of large-scale treatments - heat, cold, and anoxia - what kinds of objects were involved, and what the outcome was. Maybe someone can figure out a way to incorporate such a thing on Museumpests.net. I would guess that this dist list includes a large proportion of the people who do this work and who make the effort to examine the things after they have been treated. The information shared in this group is huge, and we should figure out as many ways as possible of making it usable. We need to know as much about good outcomes as bad ones.

Thanks to the group for all their valuable input. However, I don't recall any discussion about controlling the defrost cycle. Are there any special considerations? Off hand, I can think of the possibility of mold growth if an object is kept double wrapped in polyethylene after defrosting, despite being wrapped in tissue paper. Am I overly paranoid? Just how long should a controlled defrost take? Must the object be removed immediately? If not, how long can it go heat sealed in bags? It's not like anoxic treatment where a piece can just be kept inside its polypropylene bag forever. Any input?

So if your floors do not have a vapor barrier properly installed, the floor covering will act like a giant sponge, sucking up moisture from the floor/ground. If your building does not have the relative humidity controlled, the natural fibre floor covering will make it even more complicated to control. Mould/mildew spores will love it and flourish with abandon….ugh…especially on the side in direct contact with the floor and away from the light (mould/mildew is considered a ‘pest’, right?). Any finish applied to a floor covering, whether fire retardant or stain repellency, will be rubbed off as the floor covering is walked on/have stuff dragged across it. Meaning it would have to be reapplied periodically. So the carrier fluid would be contaminating the space again, whether water (raising the RH in the environment) or some other fluid which would off-gas in to the space as it dries.

Geiss-Mooney Textile/Costume Conservator Collections Management Consultant Professional Associate - AIC 707-763-8694 mgmoo...@moonware.net I am writing about the choice of floor covering requested by the Director's Office at our art museum. They are interested in installing either Sisal or Wool sisal in the Directors office. There will also be two or three accessioned paintings exhibited in this space as well. I am concerned about the tastiness of both of these choices (sisal and wool sisal) to potential critters. The Director's office is in a different corridor than the art collections however I am concerned about creating a potentially amiable environment for pests in general within the museum. What do people think? Should I continue to advocate for synthetic flooring options which have heretofore not been of interest unfortunately? I do not believe that they will be using a foam pad under the rug which is a good thing to avoid any potential off-gassing of the foam. I am also concerned that a fire retardant applied to the sisal may be necessary from a safety point of view. I will off course follow-up with an exam of the MSDS sheet of the fire retardant. But basically my question has to do with whether or not a large expanse of sisal is of concern to nearby collections on display.

The tree was hollowed out and had also been stored outdoors for a prolonged period. The tree was about 4 yards long and 2-3 yards in diameter. The tree was sprayed inside and out with a product called Perigen (it contains permethrin - a low-toxic synthetic pyrethroid) using a pressure sprayer. It was allowed to dry for an hour before another application was carried out. We also repeated the process a week later. The treatment revealed that the tree had been home to all manner of bugs, including silverfish, cockroaches and red-back spiders (these are similar to your black widow spiders, if you gave them a gun).

So here are my questions: Assuming that there is an infestation, is there any way to fix this other than fumigation under a tarp? I don't think there is anywhere to put it for long enough to do anoxia. At this point, does identification of the critter matter? Is there someone out there who can take on this job?

Obviously if there is an infestation, I want to do something about it, but it may be that there was water under the wood on the cradle and that freeze-thaw cycles resulted in rotting and crumbling of the wood, particularly where it wouldn't have an opportunity to dry out.

I am told that there was recent damage in the areas that rested against the cradle. (I have not seen it yet.) Some samples of frass are being sent to me - I am told there are no dead bug bodies around, but that after a piece of white paper was left on the deck, frass appeared by morning. (I suspect that maintenance staff cleaned up without reporting anything.) The piece is now in a corporate lobby (nowhere near any other works of art). So here are my questions: Assuming that there is an infestation, is there any way to fix this other than fumigation under a tarp? I don't think there is anywhere to put it for long enough to do anoxia. At this point, does identification of the critter matter? Is there someone out there who can take on this job? I would be eternally grateful. UPDATE: I received a baggie of debris in the mail. It looks like crumbs of deteriorated wood to me - can't make out any frass, but I would be happy to send it to anyone willing to check it out. Maybe the reason they couldn't find bugs was that there weren't any. Obviously if there is an infestation, I want to do something about it, but it may be that there was water under the wood on the cradle and that freeze-thaw cycles resulted in rotting and crumbling of the wood, particularly where it wouldn't have an opportunity to dry out.

Re: [pestlist] Fwd: Fumigating cabinets - bug infestation

Both high and low temperatures, of course, are as effective as anoxia, and many conservators, includin some in charge of large ethnographic and natural science collections, have used one or the other on thousands of objects over many years, with excellent results. It seems to me that high-tech has a great deal of appeal for a wide range of reasons, not all of them scientific! One, unfortunately, is the lack of access to a substantial amount of research carried out at the Canadian Conservation Institute on both heating and cooling, and including RH studies and conditions required for a complete kill. The RH situation is somewhat counter-intuitive, but has to do with what happens when an object takes up almost all of the volume of a countainer, with relatively little air. The CCI Technical Bulletin no. 29, available at www.cci-icc.gc.ca/bookstore/index-e.cfm is a good place to start. This includes specifications for using ambient outdoor weather condition for both heating and cooling, as well as the more usual sources. Some of the research, however, was published in obscure conference prodeedings, and not all are in AATA . You can find more references to the work on B-CIN (www.bcin.ca). If it's easier to look under authors, try Tom Strang.

My question is about low-temperature treatment of icons - egg tempera on wooden panels. I would like to hear from anyone who has done freezing on these or similar items - polychrome sculpture, for example - and how it turned out. Any signs of enhanced cracking? Any indications of the thoroughness of the kill? Many thanks.
