On today’s visit, I inspected and treated the exterior. I began by inspecting exterior. There was vegetation touching the house and some algae in stones and on foundation of house. These are conducive conditions for ants and other crawling insects. To combat this, I applied carpenter ant bait to the tree out front, where the source of the activity could be. I then applied a liquid application to exterior foundation. This will eliminate them using a residual product. It usually takes more than 1 treatment for ants, so if you see activity after 10 to 14 days please let us know. Thank you for choosing Green Pest Solutions!
