Good afternoon. Today I completed your one time service for yellow jackets. I treated the yellow jacket nest that they were flying into near the eaves of the roof. I also treated and removed a few paper wasp nests on the porch as well. I scrapped off a few mud dauber off the porch as well. I then treated the ground nest out back of the house along the back lawn. Please allow 10 to 14 days for our products to take effect. Thank you for choosing green pest solutions. Have a great day!
