Wasp nest in a roller shutter box — what to do

At a glance
Do not open the roller shutter box and leave the shutter itself alone. The nest sits in the cavity directly behind the rolled-up slats — any vibration provokes attacks. Keep the room window closed and have the nest removed by a professional.
Why this situation is tricky
Inside a roller shutter box, the nest sits in the narrow cavity directly behind the rolled-up shutter. If you open the box or move the shutter, the colony goes on alert — and the wasps quickly find their way into the room via the guide rails.
What to do right away
- Do not open the roller shutter box and do not move the shutter.
- Keep the window of the affected room closed.
- Do not seal the entrance hole — otherwise the wasps will find a way inside.
- Call a professional for an assessment.
Frequently asked questions
Can I still use the roller shutter?
No. Every movement of the rolled-up slats shakes the nest and provokes the wasps. Leave the shutter alone until the nest has been professionally removed.
Will the treatment damage the roller shutter box?
No. The technician works through the existing entrance hole, for example using cold treatment. The roller shutter box itself is not damaged.
How do the wasps get into the roller shutter box from outside?
Usually through a narrow gap at the guide rail or along the top edge of the box. That opening serves the colony as its only way in and out.
