Good afternoon. Today I completed your one time service for wasp activity and carpenter bees. I started off by applying a liquid treatment to the left side of the home for carpenter bee activity. When I inspected the back of the home I found two yellow jacket nests. One by the roof of the porch and one in the corner by the eaves. I applied a treatment to both nests. There were no other nests 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!
