Today I completed your one time service for bald face hornets. I inspected all areas of concern and found a nest on the left side of the house in between the gutters. A liquid residual application was applied to the area where the yellow jackets were going in and out of. This will help prevent and eliminate the activity. Please avoid treated areas for the remainder of the day. Allow 10-14 days to see best results. Give us a call if any questions or concerns should arise. Thank you for choosing green pest solutions!!
