[pestlist] insecticides

[Sasha Stollman]

Can anyone comment on Stretchmaster's Expra insecticide
[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?

Lisa, there are several formulations of permethrin insecticide that are
labeled for use on clothing.  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..

Suggestion:
Check the MSDS in detail.
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.

Hello Everyone,

I apologize for this long-winded email. 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.
