Hello, I completed your service call for bees. I was able to confirm your deck activity at the corner of where the roof meets the siding around the gutters. Due to the location in the height of the entry point, I was unable to spray directly into the affected area. I sprayed the general area of the entry point with a non-repellent liquid solution, targeting stinging insects. Please allow 3 to 5 days from treatment to take full effect. If you are still seeing activity within the next 30 days, please contact customer service for a follow up visit. Thank you for choosing Greenpest solutions.
