Good afternoon. Today I completed your first quarterly pest control service. Customer said to me when I arrived to just treat exterior only. Today I used a liquid residual product on the exterior perimeter foundation of the house. Please allow this liquid product 7-10 days for product to start working. This liquid product 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 front yard area but not the backyard due to customerâ€™s pet dogs. If you should have any questions or concerns please call us. Thank you for choosing Green Pest Solutions.
