Good morning. Today I completed your one time service for yellow jackets. Upon arrival your husband showed me above the front porch yellow jackets flying in and out along the eaves. I applied a liquid treatment to the entry point. I then walked the perimeter and found another ground nest on the small bush in front of the house. I applied a treatment to that nest as well. Please avoid the area for a few days. The yellow jackets are agitated and will sting. Please allow 10 to 14 days for our products to take effect. Thank you for choosing green pest solutions. Have a great day!
