They'll go away, if you got rid of the nest when removing the shutters. This happens a lot at our place, everything and anything that has not been moved or used, is and will be loaded with them, when you move or use whatever they are in, they will buzz around in a stupor, if you try and kill the nest during the day, many will escape or will not be home, and they seem to return to the area and will for a few days after the nest or whatever they lived in is moved or disturbed. After that they move on, these are the yellow stiped, black type wasps that make those honeycomb like paper nests with all the cells in them. I moved an aluminum extension ladder yesterday and in one of the rungs up high was a nest, I did not see them, and you know one of them bumped me square in the middle of the forehead, but either he had no stinger or who knows what, I did not get stung, had to be luck, because that is what they seem to do, fly hard and fast with that tail forward and stinger out. Many times these just bumble around the area then calm down and go back to the nest, the brown wasps, that make the same kind of nest, seem a lot smarter, recognizing you or the apparent threat to them and come out like an F-16 straight at you, no bumbling usually, and will chase you a certain distance away, and will turn back. They are more difficult to escape from, both seem to be satisfied after stinging you once, unless you have really disturbed them and stay too close. I consider any place that a nest can be made to be "hot" and test by spraying to see if any are in there before fooling with whatever it is, I hate being caught by surprise.
