Abby - Drione dust (a combination of pyrethrins and finely-divided silica gel) is an excellent choice. The pyrethrins eventually disappear, but the silica gel will act as a dessicant dust for years. It is readily available from any pest control supply house, which supplies the pest management industry.

We’re taking all the specimens out to be frozen, the props will be removed and case will be cleaned thoroughly. However the case is quite problematic as there are huge voids underneath and behind that are not easily accessible. I’m going to attempt to clean these areas while the specimens are out, but I’m wondering whether some desiccant dust or insecticide spray would be a good idea to prevent the pests returning. Does anyone have any recommendations?
