Good morning, today I completed your one time service for roaches. I applied liquid treatment to the entire office perimeter. This will help eliminate the insects as they moved through the treated areas. I also placed multiple glue boards throughout the office to help catch and monitor any activity moving through the area. Please allow 7 to 10 days for best results. If you have any questions, please or hesitate to contact the office. Thank you for your business and thank you for choosing green pest solutions!
