Is it dangerous?
Long-tailed silverfish do not pose a health hazard and the material damage is minimal. They are nevertheless considered pests because many people find them annoying. If they develop freely, they can destroy objects of high value. It is therefore problematic with Long-tailed silverfish in libraries, museums and historical collections where irreplaceable objects can be degraded and destroyed.

What can you do?

  • Make sure the rooms are tidy enough for the cleaning staff to have good room access.
  • Place handbags, backpacks and bags off the floor, and in places with good light access.
  • Unpack new things outside.
  • Remove packaging immediately.
  • If you observe a Long-tailed silverfish, contact Demand notice building operations (Lydia).

What should a leader do?

  • Preventative - pay attention to topics during HSE rounds.
  • If the leader is informed that Long-tailed silverfish are in several rooms then the leader must contact Demand notice building operations (Lydia) for a total enrollment of the problem.

What does the UiB /Estate and Facilities Management division do when a demand notice has been reported?

  • The division puts out glue traps to map the problem.
  • If there is a Long-tailed silverfish in the premises, the pest control company puts out poisonous bait. Then the pest control company checks with glue traps to make sure the stock is kept down.
