Good afternoon. Today I completed your quarterly pest control service. Today I used a liquid residual product and spot treated the floorboard perimeter of every room on the first floor of the apartment unit. I then treated the exterior perimeter foundation of the apartment unit using the same liquid product. Please allow this liquid residual product 7-10 days for liquid product to start working to see best results. The liquid product was used as a preventative measure for general pest activity. This liquid product will act as a barrier to prevent any pests from entering the interior of the unit. If you have any questions or concerns please call us. Thank you for choosing Green Pest Solutions.
