I completed your one time service. I treated and removed 3 wasp cone nest ( attic window, porch, side of home). With a liquid residual I applied product around exterior perimeter and under porch for ants and I applied same product to paper wasp nest by front upper entrance. We’ll return in 3-5 days to remove nest. Best results take effect in two weeks for ants to cross the product and take back to nest. Product is not a repellent and you may still continue to see a few ants from different colonies, that will repeat the process. Office can assist with any concerns. Thank you for choosing Green Pest Solutions.
