It is a good idea to have the insect in a 'Bug Box' whilst you use the Key - it's much easier than relying on your memory. If you've found an insect and you don't know what it is then you can use the on-line Key below to find out what order your insect belongs to. Only the adult males possess the orange tips to the wings that give this species its common name. If there are annotations or something else unique about the item, you may not wish to discard.įor more examples of pest and other damage, you may want to check out our Gallery of Horrors: When Bad Things Happen to Good Archives post, and the National Park Service's Conserv-O-Gram on Integrated Pest Management.An adult female orange tip butterfly, Anthocharis cardamines. If your object is reproduced elsewhere (such as a historic newspaper that is now available through a library microfilm or digitized online resource), you might even consider making a preservation photocopy and discarding the original, in favor of spending your disaster recovery funds on a more precious unique object that is similarly affected. Visual examples of pest damage in paper and books and guidelines on eradication can be found at the very excellent site linked above. This might involve a number of different steps, including: cleaning the area and looking for nests or egg sacs rehousing the objects into zip-closure polyethylene bags for the interim and discarding the original container if infested and it itself is not a sentimental or historic item and then possibly freezing or using anoxic methods to starve the critters of oxygen (both of these methods are best left to a professional, but resources for doing so yourself are available). Those insects leave a more visibly destructive and messier trail, which in turn, can attract even larger pest animals.Īs suggested by my colleague above, the first step is identification of the species, and then you can take steps to isolate and mitigate the problem. The larvae or adult may move on, but their leavings become a potentially interesting food source for other insects, such as silverfish, drugstore beetles (dermestids), and cockroaches, which do feed on paper and leather and textiles.
If one of these critters were nibbling on your papers, you might also notice paper-colored or darker dust or frass (bug poop) around the object, or even molted carcasses of the pests themselves. You may or not see evidence of these bugs or their larvae actively eating your newsprint, but they are certainly eating something. Īnother resource that we use at Smithsonian Institution Archives is the website ĭo you remember the song about the old woman that swallowed a fly, and then swallowed lots of other bigger and bigger creatures to get after that fly? Well, that is also a really good way to explain a key concept of Integrated Pest Management (IPM). Follow the instructions on our forum regarding mold removal. First, to clean off the bugs you will need to find a clean dry surface to gently brush or vacuum the bugs off of the papers. You can do this on a room scale by placing a dehumidifier into the space, or you can do it on a local scale by placing the affected materials into sealed plastic bags that have a desiccant in them.
For a description of Booklice, go to this handy page by the University of Pennsylvania extension service: īooklice and other pests thrive in high humidity - and paper deteriorates more rapidly in high humidity - so you must reduce the moisture in the environment. It sounds as if you may have Booklice, which feed on fungi and mold and the starches found on papers. Sorry to hear that you may have an insect problem (or as we like to call them "pests").
