Good afternoon It was a pleasure speaking with you. I completed one time service for bees you reported that bees were getting into the home. Your dad tried treating the area outside where they were possibly getting in and possibly blocked off entry or exit. I used an aerosol inside to kill as many bees as I possibly could inside of the window and sliding door tracks. I could not find where they were actually entering the interior of the home. I treated the back of the home crack and crevice and any areas that look like the bees could be entering. There was one spot that was right next to the gutter in the corner, that was very promising because yellow jackets were going into it, but it was not steady activity. Please allow 5 to 7 days for the activity to stop. If you have any activity after this time please call the office for a service call. Thank you for choosing Green Pest solutions and have a wonderful day.
