As the insecticide powder was preventing the wasps from leaving via the front of the nest outside,
they had decided to go out through the back way, which was untouched by the pest treatment.
And once the wasps had figured out their exit strategy a bit of plasterboard wasn’t going to stop
Once we knew what the wasps were up to, we re-treated the nest to exterminate the last of them.
As the guest bedroom wasn’t being used, we sealed the hole with tape to prevent any wasps
coming out until we returned a week later.
At our next visit, we carefully removed the tape and were pleased to see that there were no longer
any live wasps in the nest. The plasterboard had been weakened from the wasps’ activity, so we
removed the wall very carefully to avoid any damage to the ceiling or surrounding area.
We were then able to take out the wasp nest. All that was left was for us to reinstate the wall with plasterboard ready for redecorating.
