Today I completed your one time service for Yellowjackets. It was good talking with you today. I first started by walking around the exterior of your home and I looked for any other entry points and I did not find any others. I then treated the exterior hole above your front door with a liquid residual to help prevent Yellowjacket activity. Please allow this treatment to take two weeks for full effect as it will agitate insects. Please contact us with any questions or concerns. Thank you for choosing Green Pest Solutions have a great weekend.
