Can anyone comment on Stretchmaster's Expra insecticide [http://www.stretchmaster.co.nz/expra/index.html <http://www.stretchmaster.co.nz/expra/index.html> ], which I understand is pyrethrin (chrysanthemum extract) rather than permethrin (synthetic version)? Given it apparently contains no solvents, I would expect it to be more hypoallergenic, as well as more plant-friendly. We're considering using it to fumigate the regular bunches of freshly cut New Zealand flax (harakeke, Phormium tenax) brought into the museum for traditional Maori weaving. If we proceed, enthusiasts are likely to want to zoom it into action for collections as well. Is it more likely to have a residual component? Less likely to kill the critters? Any other concerns?

There are also several lines of outdoor and sports clothing impregnated with permethrin. Permethrin is used extensively by the armed forces and, properly applied, will withstand several washing before reapplication is necessary. Permethrin would be ideal for use in a working collection, such as theatre, as well as for museum storage. When applying permethrin, only apply to clothing, never directly to the skin.. Forrest E.

It sounds as if the collection is worn or has the possibility of being worn. If treated with such a residual pesticide, make certain it is safe for human contact for hours under very warm & moist (sweaty) conditions. If it is, I would be very much interested in knowing what the chemical is. Lisa Shockley, Curatorial Specialist, 3-D Collections Union Station/Kansas City Museum 30 W.

A local university has asked me for some help involving a pest infestation in a costume collection and I thought I would ask you. This is not a museum collection but a "working" collection that is used in the theater program, etc; however, it is comprised of period clothing from the 20th century. There are about 1900 hanging textiles and another 2000 in boxes, and they are kept in a 12' X 60' room. When the collection first came to them, it showed evidence of moth/carpet beetle damage. At the suggestion of an entomologist, the most vulnerable items in the collection were frozen, the wool and silk items were vacuumed with a mesh screen, and the room that houses the collection was periodically fogged with a fabric safe pesticide. However, the infestation has returned. An exterminating company has recommended treating the room with a long lasting micro-encapsulated chemical using controlled release technology to be done on a regular basis for a year in 3 month intervals. Are there any other options or suggestions to be considered before this chemical treatment of the room? Bear in mind, this is not a museum collection, and the logistics and cost of freezing the almost 4000 items prohibits freezing the entire collection.
