Hello! Today I completed your one time service for yellow jackets. Upon arrival you showed me 2 spots where they are entering on back of him. 1 spot is by corner of siding where 2 roofs meet in the middle and the other was to the back left corner siding where the light is hanging down. I treated entry points with a liquid residual for yellow jackets. Please allow 7-10 days for treatment’s best effects. Thank you for choosing Green Pest Solutions!
