Good afternoon. Today I completed your one time service for yellow jackets. Upon arrival you showed me yellow jackets flying in and out of the eaves. I applied a liquid treatment to the eaves along the back of the house for yellow jackets activity. I then inspected the rest of the exterior of the home. I didn’t find any nesting at this time. Please allow 10 to 14 days for our products to take effect. Thank you for choosing green pest solutions. Have a great day!
