There are few more irritating experiences than trying to prepare food while moths and other assorted denizens of the air buzz round your head and fly into your ears.
Now Sumitomo 3M, in Japan, has come to the rescue of food manufacturers with an insect repellent called Mushi Clear Film. The non-tinted film is applied to windows, fluorescent light fixtures or any other light source, where it reduces the wavelength of light emanating to the extent that most insects do not sense it. The film lets light shine through whilst keeping away insects that are attracted to light. This product is currently only available in Japan where food and pharmaceutical companies are making use of it.
