Hello today, I completed your one time service for bees. I found the yellow jackets going into the soffit on unit 219. It seems that they have already reached the building, but are stuck in the ceiling panels. At this time, we opted not to open up the panels to treat mainly because of the level of activity. I sprayed the exterior entry point with a non-repellent liquid solution, targeting yellow jackets. Please allow five days for the treatment to take full effect. If you’re still seeing activity after five days or if you have any questions or concerns, please contact customer service. Thank you for choosing Greenpest solutions.
