Good morning Maryam , today I completed your service. I started off by knocking down, all visible webbing on the property. Next, I applied a liquid residual solution that will help to eliminate ants and any other seasonal insects that may arise. Please allow 10 to 14 day shower products to work. if you’d like to have the interior treated or have any questions, please don’t hesitate to contact the office. Thank you for choosing Green pest solutions!
