Good afternoon. Today I completed your quarterly pest control service. Today I used a liquid residual product on the exterior perimeter foundation of the house as a preventative measure for carpenter bees and general pest activity. Please allow this liquid residual product 7-10 days for product to start working and then in that time frame and thereafter you should start to see a decrease in carpenter bee/general pest activity. 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 perimeter foundation. If you have any questions or concerns please call us. Thank you for choosing Green Pest Solutions.
