THE INVADERS!

It seems that a few tens of wasps have moved in our house.
They have made themself comfortable in one of the venilation bricks to the roof of the dining room.
We can even hear them chewing or talking.
No one is stung yet.
JINX!
They did not like the Aftershave I sprayed in their home. They got all disorientated.
How can i get them out of here, as they have refused to pay the rent.
Well, I don' like their smile too.
