We have a log cabin in the mountains of north Georgia. We are only here for part of the year. For the last several months, we have had wasps appearing in the house, usually in the second level, around a large window. So far today, my husband has caught and released over 40 black wasps. We cannot determine where they are coming from. They don’t fly around which would allow us to see where there are many of them. They just seem to appear.
