Hello, Chris from Green pest solutions here, upon arrival and thank you for allowing me early since I was only one street away doing another exact same service. However, I came over inspected the area and I did observe yellow jackets going under the wood pile that’s underneath that pine tree in your rear yard. I thoroughly treated that and the surrounding area Because I saw other stinging insects such as hornets and paper wasps and bumblebees flying around and landing on the ground there. They possibly could be going and feeding on the sap that the pine tree is putting out. Anyway, I treated the area. Please stay away from it till tomorrow morning and the yellow jacket nest will be 100% deceased and all the other stinging insects as they land on the treated areaday two will follow victim to the application and be eliminated. Thank you for choosing Green customer solutions and have a great rest of your day.
