Hi Lars,thanks I will look at it. I have now given poisen all over the apartment and the places where I have found them. I so far found them 2 places in my bedroom and in my kitchen.
I have learned that plastic bags do not keep them out. They can bite holes in them to get inside the bag. I took some comics where there was silverfish in them and put them in bags so I later could check the comics for bugs and kill them. When I got the time to check them the bags had small holes in them so they had escaped the bags
I have also read that flower Lavandula does not make silverfish happy, they do not like the smell of it, so I will try to see if I find a few in the garden shop today for my apartment to see if it works So far I have found 20 silverfish and yesterday was the first day for me where I have not found any silverfish. I am now nearly done in the bedroom. I only need to check one closet more. Then I will begin cleaning everything in the kithen and check all closet there.
I have also bought some big plastic boxes for some of my items. I will buy some more today to protect my things. The strange thing is I have a bookcase in my bedroom and there are no bugs in any of this books. Why the **** to they want my star wars in big closed closets more
I believe silverfish prefer the dark, and come out more at night. Your bookcase is probably not as desirable to them since presumably it's effectively in daylight for half of the day. Whereas a closed cupboard or closet gives them darkness all day long
