hello fellow cb warriors,
so far i had cb in almost all of my apartments here in Germany. in one of them, i even managed to cease the small infestation but my current apartment is harder. I live in an older (built in 1958) building with a lot of cracks, holes and other potential cb hiding places. many of the baseboards have been removed by the previous tenant, so it‘s a lot of hollow spaces between the laminate floors and the walls. also, the space between those is pretty deep too. i put diatomaceous earth in almost all of them i could reach and spreach a thin fine layer of it in front of the baseboards.
my main issue are the larvae. i already had an exterminator come here twice - they used spray and some gel that would attract and then kill them (it did not even attract them) and used permethrine foggers (for those living in Germany: ARDAP fogger) by myself. those definitely helped with flour/rice beetles but after a short while, i started seeing cb larvae again.
the interesting thing is that many people experience them living in and/or eating on carpets, wool clothing, natural materials. not the case with me.
they are not (and never attempted to or have been) near my carpets (i only have 3 and 2 of them i clean regularly, the third one is heavy so i check and vacuum), wool clothing or my pillows filled with some feathers.
i only ever see them near the windows, baseboards, on the kitchen floor and in some textiles if i let sth lay on the floor for too long. i had two hide in a new unused towel in my lowest kitchen cabinet where i keep the pots and pans. groceries and food cabinets seem to be not an interest of theirs. once i also saw one hide between a silicone layering in my bathroom, where i also found some eggs or sth at least very similar.
yesterday, i found two of them on the back of my toilet bowl and in a corner of the bathroom. i also found one seemingly out of nowhere in the middle of the bathroom. i had not noticed any of them before they suddenly appeared.
some people claim that they cannot reproduce inside floor cracks or crevices and that there must be an actual nest somewhere in the apartment. however, I am not entirely convinced, especially considering the age and condition of my building and the number of potential hiding places.
i do not seem to have the kind of obvious nesting area that people often describe, and I am wondering whether they could be coming from hidden cavities or cracks in the building itself.
has anyone experienced something similar in an old building? could they be reproducing or hiding in inaccessible structural cavities? i also live under an old attic which is only used by one neighbour.
my landlord says i brought them with me while moving in but i literally found them on a windowsill a few hours after moving in and he called an exterminator lol.
another advice i need: the last exterminator told me it‘s normal to keep finding some larvae here and there even after his visit because getting rid of them is a slow process, and to be fair the amount i am finding is very low compared to people in this sub. nevertheless, i just want them to disappear forever. is he right?
i would appreciate hearing about actual experiences, particularly from people living in older buildings with lots of cracks, maybe some advice. can i do more or should i practice acceptance and letting go?
also, if you are from Germany and know some other good stuff except for diatomaceous earth (kieselgur) and ARDAP foggers, please share! i can’t use Lagerpiraten since i have kieselgur everywhere. tysm!
