Good morning. It was nice talking to you today. Your one time service was completed this morning. I applied to contact treatment directly to the yellow jacket nest for yellow jacket activity. I applied a liquid residual treatment directly to the yellowjacket nest next to the back door to eradicate the nest. This treatment is is Taylor specifically for communal insects like yellow jackets. If you have any questions or concerns, please contact the office. Please allow 7 to 10 days for the effect of this treatment. Thank you for choosing Greenpest Solutions.
