Maintaining your insect collection display
Maintaining your insect collection display can be easy and if done properly will allow your insect collection to last a lifetime. Inside the insect display box you should place flakes of moth balls. This will discourage future infestations. I like to crush the mothballs and put them into a very small vial with tiny holes in the lid. I secure the vial to the inside lower corner of the display box.
Although mothballs are excellent for keeping out pests that would destroy your specimens, they do not kill pests already infested. You can tell a specimen is infested when a small pile of brown dust or fraz shows up under the specimen. In this case I remove the specimen and place it in the freezer for several days. This seems to kill the pests and I return the specimen to its display.
