Information about bedbugs in the library

Published Sep 09, 2025

During an inspection by Anticimex, bedbugs were detected in the KTH Library. Thanks to Anticimex’s swift response, we were able to confirm that the occurrence was limited to three armchairs in the South-East Gallery. The affected furniture is being removed and immediate measures are being taken.

The furniture and the South-East Gallery have been inspected and secured by the bedbug-detection dog Jackson and Anticimex staff.

The area has been secured with the help of specially trained dogs, and further actions are being carried out to ensure that the problem does not spread.

Since the library is open to the public, such incidents cannot be completely ruled out. Unfortunately, we have now been affected, but we are doing everything we can to resolve the situation and restore order.

KTH will also review routines for both action and communication in the event of similar future incidents.

The library remains open, and we ask for your understanding of any disturbances during this work. South-East Gallery, where the affected furniture was located, will remain closed until Monday, 22 September.
