Hello Claudia,
I am sorry for answering that late – it was holiday time in between … 😊 But to reply to your question which traps I can recommend for using … WHAT WE HAVE TESTED IN HILDESHEIM - HOUSEHOLD PRODUCTS As the museum is not funded by the government but has to deal with “income” on its own there is in general “no money for anything”. That is why we started with household products from the regular drugstores in Germany, namely “dm” and “Rossmann”. The types of products they are selling are “glue traps for …” (e.g. silverfish, specific flies, pests in general etc.) and “bait for …” (e.g. silverfish, ants etc.). https://www.dm.de/search?query=falle <https://www.dm.de/search?query=falle&searchType=product> &searchType=product (en “trap” = german “Falle”; en „bait“ = german „Köder“) The “glue traps for silverfish” was not really working. One would expect having an attractant included within the glue (as the product is called “… for silverfish”.) But that seems not be the case. It is more likely that this product is just a regular glue trap without any additions which is just working because you place it in a quite area on the floor. The function of the baits is that the gel is placed inside a tiny metal box and it is a mixture of an attractant and poison. So the specimens are attracted to the gel, feed an that, within that feed the poison as well and then running somewhere else where they would die. Not a good idea in our surrounding as dead specimens work as a food resource for other pests. https://www.dm.de/search?query=k%C3%B6der <https://www.dm.de/search?query=k%C3%B6der&searchType=product> &searchType=product But the combination of the “glue trap for silverfish” and “bait for silverfish” was working quite good. The disadvantage is you would then have to open the metal box with the bait gel and place a bit on the trap. It takes times, can be a mess and you are working with a poison (what is not needed in that combination). As there was already the rumour of using dry food for dogs as attractant we were testing that as well. And that worked the same way as with the bait. - PROFESSIONAL PRODUCTS I have been on the “Exponatec” fair (specialised fair for conservation and museology topics in Germany) just some month before that project which took me to Hildesheim. https://www.exponatec.com/?_ga=2.95002271.2059273849.1631872149-1052875370.1631872149 And the company Pankow had a booth there and offered “test-kits” of their products. So we had the opportunity to try the new version of the “S-Trap”. (The former version was developed for silverfish. But the new version is recreated for the grey silverfish and has now bigger entrance holes. That is what I was told.) No need to say that those traps worked best. Not just that the attractant was obviously more “attractive”. But the main advantage is the closed shelter with a gel inside where the specimens sinking in and therefore are not available as a new food resource for other specimens. EXPERIENCES FROM AN ARCHAEOLOGICAL SITE - OVERVIEW I am also working at an archaeological site in Egypt where the finds from one tomb are stored in another tomb which is already empty. Within that project I am responsible for the IPM as well and the same question occurred: which traps should we use to get an idea of what we are dealing with? What we have recognised very early (2017?!?) was that we have minimum of species from the family of Zygentoma. (in the meantime we are sure to have two different species.) But there have been several points to include in our decision: - Working at archaeological sites is usually limited to some month within a year. In our case we are there normally for 2 month. That means the tomb is closed for 10 month, everything can happen and nobody will realise it before the next working season / the re-opening in the following year. - As usual in Egyptian tombs: there is no solid and completely closing door. Just a metal net fixed within a metal frame. It is more like a lattice or grid which means everything in the size of mice or smaller can just enter whenever they want. - We are located in North Africa rather than Europe. So we are dealing with species that need to be identified first to figure out if they can be considered as “pests” in our definition. Therefore we would need some specimens in a good condition. - RESULTS We have tested the same products and combinations as I did in Hildesheim and those have been the results: The household products were obviously working quite well. But the “S-Trap” from Pankow was better due to the reasons already mentioned and in this specific case even more: - The regular traps were completely dusty which lead to a less efficiency of the glue area (especially after several month). - Also we mostly found remains of specimens which means they have been eaten by other specimens. That lead to the problem that they are not countable in a proper way. (And because we couldn’t count them adequate on the several traps we had placed - we had no chance to figure out in which “rooms” of the architectural construction they occurred most or if they are really entering via the open exit or more likely via fractures in the hill from nearby tombs.) - Now and then some small stones have been fallen off the ceiling and landing on the top of the traps. That caused the upper side being stuck to the glue area and the trap could not function anymore. - At last a very practical disadvantage: the traps need to be transported to the office of the excavation house to be documented and counted. But transportation of a bunch of regular traps while walking “home” is not an easy task, because with just a little bit of pressure it very often happens that the upper side is stuck to the lower side with the glue area and the traps can not be opened anymore. The “S-Trap” turned out to be the proper solution within that specific area. - Not just that the specimens were trapped within the plastic box and sunk into the gel (and therefore countable and not a resource for others). - It also turned out that when we were controlling the traps several alive specimens were still running around in the boxes so that we were able to collect some of them for further investigations. - And of cause no dust or falling gravel is influencing the functionality of the traps. - At last the enclosed containers in combination with the outer shape of the traps make them easily stackable (placed upon each other) and therefore transportable without any damage. TO SUM UP - for private households I would recommend the combination of a regular glue trap with dogs fodder for private households as this is cheap, you can just buy the trap and the fodder in any drugstore and there is no poison included (as with the bait). - for professional surroundings In the future I will always go with a trap like the “S-Trap” from Pankow if there is enough money in the museum / the project for the mentioned reasons. I hope that helps a bit. 😊 Best wishes from Germany.

And that roll of toilet-paper was standing in my private kitchen! (The toilet-paper was used due to the lack of regular kitchen-tissue-paper. The photograph was taken with an iPhone.) Here is the story to “How it / they got there”: 2018, Hildesheim, Germany In 2018 I joined a project in a museum in Hildesheim, a town very central in Germany. While being there I was asked not just to work in the project itself but also to help with the regular tasks of the conservators. At the same time an exhibition was planned to open soon which consisted only of paper-based materials (prints, sketches, photographs …). Just before the opening the volunteering curator of this exhibition came to the conservators workshop asking for help as he has seen “strange creatures crumbling around”. I was asked to took over this task as I had dealt with pest management before and so we were checking the rooms where the temporary exhibition was installed. At the time we removed the first picture from the wall a huge infestation was obvious. (Later research has shown that there was a flooding in the basement several years ago and that within the cleaning of the affected rooms an infestation was already realised but it was not clear which areas of the building were infested, there was little known about that type of pest and the museums conservators had to deal with a lot of other things. As usual.) What we have done for the time that I joined the project were two things: 1. Every two weeks on Monday (governmental museums in Germany are closed Mondays) we took of every single object from the walls and collected all specimens we could find. We could do that together 8 times before the exhibition run out and at the end we had collected about 240 alive specimens. 2. We started with testing different materials and methods. And we figured out that the basic problem was the specimens were living / sitting behind the hanging objects and not coming down to the floor on their own. So the regular glue / blunder traps and diatomeen were not working. After that we have tried using glue traps with additional attractants (from drug stores and the S-trap from Pankow). This was working already better but the problem was where to place these traps in a running exhibition with nearly nothing standing around. I left the project and so the museum at the same time when the exhibition was finished and these rooms were used as a temporary storage within the movement of the whole objects storage. So the tests didn’t go on and I don’t know what the situation is now. But when I left I packed my private stuff in cardboard-boxes from the museum to transport everything to my flat … (The boxes were old ones, having been used already several times in the museum and of cause have not been treated. They stayed for about two weeks in my museums-office – in a completely different architectural area that the investigated rooms – before I could go back and take them home. And I transported them with a rented car.) 2019, Cologne, Germany When I repacked everything at my private home one specimen crawled out of one box. I caught it and hoped that has been the only one. 2021, Cologne In the last two years it turned out that it wasn’t that way. I have already collected several specimens at my place – in the home office room, in the kitchen and in the bathroom. Till now they occurred very seldom so I have just collected them in the idea to give them to a colleague who is doing further research on treatments (a paper conservator). But I have tracked three specimens in the last two days and I guess now it is time to place some traps with attractants … So far. Just a private story of spreading C. longicaudata from one building to another, in fact one city to another. Best wishes from Germany Antje PS: If someone likes to have a specimen for a referencing pests collection I am willing to go on with active collecting – rather than passive collecting via traps – and send them wherever needed. But please note that I am just sending them as dead ones. I don’t want to spread them even further. 😊 Antje Zygalski Conservation Scientist, specialised on Ancient Wooden Objects (M.A., Cologne Institute of Conservation Sciences-CICS) Conservator of Wooden Objects and Furniture (state-certified three-year apprenticeship) Carpenter / Joiner / Cabinetmaker (state-certified three-year apprenticeship) a.zygal...@googlemail.com <mailto:a.zygal...@googlemail.com> 0049 - 173 – 67 222 32 <https://independent.academia.edu/AZygalski> https://independent.academia.edu/AZygalski ______________________________________________________________________________________________________ interest of research: ancient Egyptian constructed wooden objects ______________________________________________________________________________________________________ <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> Virenfrei. <http://www.avg.com/email-signature?utm_medium=email&utm_source=link&utm_campaign=sig-email&utm_content=emailclient> www.avg.com -- You received this message because you are subscribed to the Google Groups "MuseumPests" group.
