Hi Nicole As Pascal mentioned, the temperature is going to be critical in ensuring that you achieve 100% mortality. When testing powderpost beetles Dr Mark Gilberg found that it took up to 12 days to kill all stages at 30C and 70RH. You’re using a lower RH than in that test which should reduce the time, but it takes longer to kill insects at lower temperatures (i.e. up to 6 weeks at 20C). If the temperature where you are treating the objects is low you will need to increase the temp. Oxygen scavengers take a number of days to reduce the oxygen level so you need to allow for this when thinking about treatment time as well. Regarding the Anobium life cycle, the adults emerge in late spring/ early summer. This means that there would be minimal risk of cross-infestation as the borers will be in the larval stage at this time (unless they are from the southern hemisphere, e.g. Australia, where the beetles are emerging now).
