Good evening. Today I completed your quarterly pest control service. Due to the cool temperature this evening, there were no signs of bees or bee-like activity. Today I used a liquid residual product on the exterior perimeter foundation of the house. Please allow this liquid residual 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. If you should have any questions or concerns please call us. Thank you for choosing Green Pest Solutions.
