Use of Napthalene or any other chemical insecticide has been the tradition in insect collections but, with our increased knowledge of the negative health problems associated with long exposure, quite a few institutions are now moving to air-tight cabinets and regular freezing of boxes to keep pests down. I have used Vapona cut into little blocks and pinned into my storeboxes but I am phasing this out and will just keep a good eye on my boxes and freeze them regularly.
