Hello I completed your quarterly service today. The bait station by the home showed moderate feeding while the one by the shed was empty. I refilled both stations with fresh bait. I also applied a liquid treatment to the perimeter foundation as well as to a yellow jacket ground nest in front of the home. Please allow 5 to 7 days for yellow jacket treatment to take effect. If you have any pest issues, feel free to give us a call. Have a great day and thanks for choosing Green Pest Solutions.
