I put the box with the butterflies or moths inside the freezer for a few days. If you freeze a wooden box of specimens it is advisable to put the box inside a large plastic bag and seal it before putting it in the freezer. It is very important to leave the box sealed inside the bag for at least 24 hours after removing it from the freezer before taking it out of the bag in order to allow the whole box to return to room temperature. If you take it out of the bag when still cold humidity will be absorbed by the box, and if it isn't completely airtight humidity will also be absorbed by the specimens. Adam. Thanks Adam for the advice ,I have to say that I don´t use the plastic bag but until now(I´ll knock on wood)I have not apreciate humidity,boxes are very hermetic,but I´ll begin to put them in the box like you say.

It's not so problematic in places with very low humidity, but it is better to be safe as humidity in most places is higher than you may imagine. If you take a glass of fridge cold water (never mind frozen) and put it on the table and then see water droplets form on the outside of the glass you will know that it is too humid for safety.
Adam.
