I would like to point out to you that there are plenty of other ways
to treat insects, perhaps more sustainable methods, and chemical
treatment is only advised as a last resort. The advantage of
integrated pest management (IPM) is that the emphasis is on
Prevention. Thus many problems do not even occur when the museum is
properly monitored and if they do occur measures are taken in a very
early phase of the infestation. Methyl bromide is banned in Dutch
greenhouses and human studies have shown that the chemical affects
the lungs. You can read more on pest management and IPM in
R.Teygeler: Preservation of archives in tropical climates (2001),
see chapter 7. This publication can be consulted online at
