Good Afternoon, It was nice to see the family again. A light amount of roach and ant activity was described. I applied a residual liquid treatment for ants and roaches. To the available 1st floor, basement, kitchen, bathroom and exterior perimeter of your home. the ants and roaches will transfer the treatment as they cross over it. 1 ant can kill up to 40 back in the colony. It works the same way with roaches. Please allow two weeks for best results. Thank you for choosing Green Pest Solutions and please call with any questions or concerns
