As an entomologist and one who has spent his career setting up Integrated 
Preventive Pest Management (IPPM) programs for museums, historic houses, 
collections, libraries and archives around the world for the past 41 years, one 
must consider what kinds of pests may be considered pests of collections or a 
structure.
 
In reviewing the list, I would consider certain kinds of carpet beetle adults 
(feed on pollen), cigarette beetles (feed on dried plant materials), and 
drywood termites and wood-boring beetles (wooden natural materials and objects) 
to be of concern.  
 
Carpet beetle adults tend to feed on composites and bridal veil.  So 
chrysanthemums and daisies might be of concern.  However, if we are talking 
about cut flowers, I do not consider even these to be a problem.  When a carpet 
beetle adult is disturbed, it folds its legs and antennae into grooves of its 
body and rolls off the flower like a lead shot or B-B.  Or they may just spread 
their wings and fly away as the flower is being cut.  Roses, tulips, daffodils, 
and all sorts of other kinds of flowers would be fine.

Cigarette beetles are often found infesting dried flower arrangements and dried 
plant material on display, such as a string of dried chile peppers.  The are 
also a "bookworm" where the larvae feed on the glue of the binding.  And they 
often feed on paper mache items, such as mortuary masks and puppets.

Wood-destroying insects should be considered when felled logs and branches are 
being considered.  Powderpost beetles should be considered when donated 
furniture arrives from Aunt Ida's basement or attic.  Or the contents of a 
cobbler's shop.
 
What is equally important is what kinds of traveling exhibitions and temporary 
demonstrations does management allow.  For instance, never allow a weaver to 
set up shop in a museum; these well-intentioned demonstrations often infest 
museums with webbing clothes moths.  And don't use real wool in your diorama of 
pioneer life; use synthetic "wool".  The same goes for the importation of woven 
woolen items into a museum shop.  Taxidermy mounts....ugh.

I can't think of any reason succulents are on the list, if we are just talking 
about insect infestation.  The same goes for plastic or silk or waxed flowers.  
Carpet beetles do not feed on plastic, silk, or waxed flowers.  Carpet beetle 
larvae require keratin (an animal protein) in their diet; silk is a mineral 
spun from the salivary glands of a moth larva.  It does not contain keratin, 
even though you see time and again references to carpet beetles feeding on silk 
in the literature; it's simply not true.  Silk damage is usually caused by UV 
light and silverfish feeding on the sizing.

That brings me to silverfish.  Every time you receive a cardboard box into a 
museum, you run the risk of importing silverfish inside the corrugations of the 
box.  Box manufacturing plants are loaded with silverfish.  They feed on the 
glue and labels.  So what is one supposed to do?  Nothing....that's life.  
Insure you have a thorough IPPM program in your institution with lots of 
glueboards.

Hi Dawn,
 
We include this on our list to insure that all the arrangements are of quality 
material.
 
Best,

I’m curious – you permit real, cut flowers but not artificial ones? Would you 
mind explaining your reasoning for that?

Hi All,
 
I am preparing to generate a list of prohibited items to give to some Ikebana 
flower arrangers who are going to have their arrangements accompany an 
exhibition next spring. We currently have an existing list--however I was 
hoping to flesh it out so as to provide more of an explanation as to why these 
items are not allowed in the museum. Does anyone have their own list of 
prohibited items that you provide to florists? Would you be willing to share 
said list with the listerv? Is there anything that you would add or remove from 
the list I provided? Any thoughts would be greatly appreciated!
 
Best regards,
Erika Wingfield
