Anoxic treatment on a building is very possible. Grain silos were purged with nitrogen during the Second World War preventing food lose to rodent and insect populations. Textiles from 1890's have changed color under Vikane, off white to a yellow white from the acids. Most companies will tell you your Art is safe, not always true.

Many years ago conservation scientist Jim Duizak at the Getty Conservation Institute did research on Vikane and found that the commercial formulation contained residual organic acids that would tarnish and etch metals and affect other acid sensitive materials. I talked to Jim about it and he told me that the lab-grade Vikane was free of the acids but was too expensive to use commercially. He recommended removing acid-sensitive collections before the fumigation of a whole historic house with a commercial Vikane treatment. I understand that Vikane is considered useful when a whole structure requires fumigation / eradication such as with a termite infestation in the structure. It does have deep penetration and once done and the tenting removed it does not leave toxic residues. I have not heard of an anoxic treatment for a whole building - is it even possible? What are the alternatives to the use of Vikane for a termite infested building? Cheers!

It certainly will tarnish silver and certain other metals. It has amazing penetrating properties and therefore would not be able to be confined to the lobby area of the museum. I like the dog suggestion; however, if they're in the ceiling or walls, a dog would not be able to detect them. In California, with small infestations, a type of ray-emitting gun is used to fry 'em in their galleries. I don't know if anyone in Florida uses this device. I agree with Mr. Louche - research, research. A lot can go wrong with a Vikane fumigation. Thomas A.

We have determined that we have drywood termites infested in the front lobby of our museum. Our extermination company of course wants to fumigate the entire museum. We know that this not possible, so my questions are as follows: The exterminator wants to use Vikane Gas. Is this the correct gas to use? Will it harm artwork if the gas leaked into a gallery? Is t his the proper way to exterminate drywood termintes? This is definitely not something that we have ever had to deal with before, so any suggestions on how to fix this infestation would be greatly appreciated.
