As Keratin is clearly a good part of furs as well, I will definitely see no reasons why it should be acceptable on furs and not on feather. If I understood correctly, we are talking about backing inside and in no circumstances powdering the outside of the skins or feathers. Your concern of drying may be more related to general RH fluctuation stress rather than the root causes of using borax, but it is certainly worth looking further. You may want to check this ref : The organic chemistry of museum objects, John S. Mills Raymond White, Butterworths, 1987, London.

Re: [pestlist] wasp nest in sculpture
This is a message from the Museumpests List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe please look at the footer of this email. --- Dear Bernice, Just an advice from a bronze and patina specialist that does this repeatedly over the years. First, using any pesticide will effectively kill the wasps but potentially damage the sculpture patina. Therefore, fiscally removing the nest by water of vapour jet stream is a reasonably good option following some logical steps. Deep night intervention will ensure some passivity on wasps self defence reaction. So good operator protective thick clothes covering risks of punctures is a prerequisite (let someone else double check before stepping on the operating area). Use a powerful jet stream fit with a sharp nozzle able to cut trough light wood (test it elsewhere) and a long handle to be able to approach as close as possible from a lateral angle to cut the nest from the bronze surface not jetting on the bronze too hardly. Wetting the bronze will not change anything from an ordinary rain, but applying the nozzle front to the surface will affect rapidly the patina surface (as any chemical will do with after mentioned treatments). It is good the day before night to come to plan the direction of the nozzle movements when plenty of light is available. When the nest is on floor, then use pesticide to fill and prevent restoration of their habitat at dawn. Then you may place it on a disposable area. Fire brigade are usually quite incline to deal with this step as for the killing if you wish. Finally days after, when any activity is definitely over, you can come manually to remove all remaining traces of the nest as reported to prevent any return. If needed, you can always repeat this process. Remember that bronze hollow outdoor sculptures are potentially always quite good nest pest of all kinds. Hope this help.

It seems that the nest is embedded somewhat within the sculpture so there is limited physical access. I’m starting to think a pesticide will be necessary… -- To send an email to the list, send your msg to pestlist@museumpests.Net To unsubscribe from this list send an email to pestlist@museumpests.net and in the subject put: unsubscribe - no quotes please.

This is a message from the Museumpests List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe please look at the footer of this email. --- Dear Stevens, Although pest control is not my speciality but may I suggest you to contact the Swiss Open-Air Museum Ballenberg. http://ballenberg.ch/en/Info/Contact They do have an indoor beehive open to the outside (building rear) for bees by a transparent channel visible to the public. The public is quite impressed by this setting and the only comment we may give is the odour the setting is releasing (not necessarily pleasant). Beside this, it is quite nice and very didactical as explanation are directly visible (social rules etc...). Hope this help.

I agree that a museum setting might not be the best place to have an active hive.. Especially with regards to paying visitors and Bee sting allergies! However it could be an interesting web cam project if remotely located. I forwarded the link to the Haven project to a friend of mine who leads an urban beekeeping effort in Minneapolis...

Speaker: Jarrett Mellenbruch http://deepecologyproject.com/ Presentation: HAVEN Jarrett Mellenbruch studied at the Rhode Island School of Design and has exhibited his work in New York City, Kansas City and Tokyo. He is a third-generation beekeeper and an adjunct professor at the University of Missouri - Kansas City Department of Art and Art History. HAVEN is a proposed nationwide network of living beehive sculptures for both honey bees and native bees. Unlike conventional honey bee hives, which have been developed for the easy harvesting of honey and other bee products, and need frequent maintenance and hive management, HAVEN is a self-sustaining hive designed solely to promote the well-being of its honey bee inhabitants. Prototype development for HAVEN was funded by a Rocket Grant from the Andy Warhol Foundation and the project launched with an installation this summer in a public garden in downtown Kansas City, Missouri. The goal is to place 1,000 HAVEN sculptures in parks, gardens, museums, universities and private properties around the country, thereby creating a coast-to-coast sanctuary for honey bees and a educational interface for natives. HAVEN seeks, through the power of art, to effect real change in the current honey bee crisis, as well as to raise public awareness of the importance of native pollinators and the interconnectedness of all species.

[pestlist] Killing pests with microwaves
This is a message from the Museumpests List. To post to this list send it as an email to pestlist@museumpests.net To unsubscribe please look at the footer of this email. --- Would someone have scientific references and more general information on suggested technologies to kill some historical building wood beam pests? They have yet not responded to repeated standard fumigation, anoxia and injection treatments, mainly due to lack of access. The life cycle seems to be between 4-5 years before becoming fast-growing adults. Please do not ask his name, as I have had inconsistent identifications, but life is certainly there as fresh saw dust is produced repeatedly and in high quantity. The now suggested method is to uses microwaves (frequencies between 300 MHz (0.3 GHz) and 300 GHz) set to heat up to 60 deg. C.
