I am trying to locate the discussion thread on 'Wasp Removal'. I found this by a Google search.
I have wasps that have moved into an old house (entry between the wall and the roof line) that we use for storage. Their point of entry is directly above the entry door, and only about 2 feet from where I have to stand to unlock and then enter the house. Just got stung, and they are quite large and aggressive.
Besides waiting for winter (by the way I live in Alberta, Canada) what does anyone suggest? We live just north of Montana (about 2 hours driving time) and the weather during the day averages from 85 to 100 degrees. While it does cool down at night, not that much (say to 60-65 degrees). I will be October before we have any significantly cool weather.
