Good morning. It was nice speaking with you today. Your one time BEE service was completed this morning. I applied a liquid residual treatment directly underneath the siding where the yellow jackets were nesting. This is a slow acting non-repellent solution that will quickly spread among the nest to control the hive. You may see an increase of activity and then a quick die down. If you have any questions or concerns, please contact the office. Please allow 7 to 10 days for the full effect of this treatment. Thank you for choosing Greenpest Solutions.
