Good morning. Today I completed your quarterly pest control service. Per customer request, I used an interior liquid residual product and spot treated the floorboard perimeter of the basement of the house as a preventative measure for general pest activity. I then used another liquid residual product on the exterior perimeter foundation of the house. Please allow these two liquid residual products 7-10 days for the products to start working to see best results. These liquid products will leave an invisible band that the pests do not know is there, they cross over, pick up the chemical on their sticky appendages(legs) and possibly transfer the chemical back to each other, eventually it will catch up to the pests and kill them. Finally, I used a moisture activated granular around the exterior perimeter foundation. If you have any questions or concerns please call us. Thank you for choosing Green Pest Solutions.
