Wasps – In Fireplace Vent

Q: I have wasps living in either my fireplace chimney flue or the vent for the fireplace. Even after the cold snap, when I light a fire a few wasps come into the house. How can I rid my fireplace of wasps?

A: My guess is that they are somewhere in the chimney flue rather than in the vent. I would think that the heat of the gas logs would have killed them in the flue already.

So if they are in the chimney, someone has to find the crack through which they enter which might be easier to do in summer when they are active.
