Sealing up the fireplace from inside the house
I've got stink bugs coming down through the chimney, out the fireplace, and into the house. I'll get the chimney capped off soon. But first, I need to seal off the fireplace opening so they stop getting into the house. What type of tape would you recommend using? I'll put plastic around the fireplace opening and then seal it with tape to the fireplace brick, but I don't want to use a tape that will forever mark up the brick (either leave adhesive or change its color). Any ideas?
