[Sílvia Sequeira]

Thank you all very much for your answer, but we are trying to get a
pesticide free option, maybe the sealed packaging could be a good
alternative.
Does anyone have experience in preserving this type of collection in
microclimates?

Packaging an object in a sealed barrier film bag will protect it from a variety 
of threats (including insects). This is a well-established procedure in many 
industries (especially foodstuffs). A great deal of effort, study and funding 
has gone into the development of these methods.

Of course, the microclimate thus created must be carefully considered (in 
industry, this is called MAP or modified atmosphere packaging).  MAP has many 
attractive benefits.

One aspect of barrier packaging is that while it prevents insects, pollution, 
dust, etc from entering the package, it also locks existing poisons in the 
artefacts inside the bag. This mitigates most of the problems involved in 
handling and storing poisonous objects. 

Packaging in clear barrier film bags, perhaps using oxygen absorbers, might be 
an option for some or all of the collection. Of course, this depends on budget, 
size of collection, expected use of collection, etc.  However, it is a real 
possibility, and should be considered. 

There's more general information on anoxic packaging in my new website at 
www.keepsafe.ca

We are conservators at an investigation institute, in Lisbon, which has many
different collections related to tropical countries. Our biological
collection comprehends a unique insect’s compilation, several skeletons and
stuffed animals. Currently and for almost one century, this collection has
been frequently sprayed (twice a month) with commercial insecticides and
naphthalene balls have been placed in the specimens’ enclosures as a
preventive measure. The collection director can not put at risk these unique
specimens, so he continues to apply these toxic products.

Due to the obvious reasons we are searching for a non toxic option, which
would prevent the vulnerability of this collection to pests, at all levels.

We are aware of the disinfestation methods with anoxia, CO2, freezing and
heat treatments, but they are not preventive.

The freezing permanent storage could be an option but we are not sure if
would not damage some of these fragile specimens.



Does any one have an advice for preventive solutions, besides IPM, since,
with this program we can not assure 100% protection, and we can not afford
losing any specimens?



Many thanks,

To Silvia Sequeira
There are a number of products now on the market based on the insecticide 
transfluthrin. This is a synthetic pyrethroid which readily vapourises into an 
insecticidal gas. It has been found very useful in slow release packs for 
fumigating closed ares such as drawers, cupboards etc. There are a number of 
suppliers of proprietary products containing transfluthrin including IBA, 
Rentokil etc available in Portugal.
I am using it with success.
