Hello,
we moved into our new building in October. Shortly after, we noticed that there were small beetles everywhere.
After 4 weeks of heating and ventilating, we called an exterminator.
He found out that they are yeast beetles (supposed to be like booklice) and that he can get rid of them.
After 4 treatments with short-term insecticides, the situation has improved, but the beetles are not gone and new ones come every day.
We have observed that the beetles come out at the edge insulation strip of the screed.
We are looking for someone who has experience with this and can share it with us.
Thank you very much
