Today I completed your one time service for both yellow jackets and European hornets. I inspected all the areas of concern and found a yellow jackets nest by the front of your home. I applied a liquid residual application to the entry point. This will help prevent and eliminate the activity. I then checked underneath the deck as requested and no activity was found. I also, inspect the shed outback and found an European hornets nest which I sprayed and removed. Please avoid treated areas for the remainder of the day. Allow 10-14 days to see best results. Thank you for choosing green pest solutions!!!
