Today I completed your one time service for Yellowjackets. It was good talking with you today. I went around your home and looked for any other entryways. No other entryways were found except for the two that you found. I then sealed up the hole on the interior to prevent them from getting inside. I then treated both holes 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 day.
