I have red wasps (see below) that are coming in and out of a little metal vent outside my bedroom window. I keep finding dead wasps in my bedroom below the vent....I have my window tightly closed and air vent in ceiling closed, yet I keep finding them. Found two live ones....one stung me and I had a horrible reaction to it...was very sick. Because I can't get to the nest (the vent sticks out of the building and is about 4" wide and 4" out) and I know there is a colony in there, I can only kill them as I see them. I want the queen and whole colony killed. What do I do??? They are very aggressive and angry wasps.
