Today I completed your one time service for oriental cockroaches. I started by doing a visual inspection of the interior. I have a completion of my inspection. I didn’t notice multiple entry points in the ground on the right side of the salon. The entry points run all the way from the back of the salon to the front of the salon. I believe this area is where the oriental cockroaches are answering into the salon. I did point out to you, but I will also post a picture to the account for reference. I recommend having a sealed up by a professional. As far as treatment goes, I applied a liquid treatment to the entire salon, perimeter and directly into each entry point. I also placed glue boards in the areas that are not accessible by a customer. Please allow 7 to 10 days for best results. Thank you for choosing Green pest solutions!
