The service rep. was prompt and quickly confirmed with us the primary issue. He evaluated key locations and also did a broader assessment. He validated the carpenter ant problem, treated the area internally and externally, as well as treating the circumference of the house. Asked if there were any other issues/concerns. Offered direction on the treated areas and provided specifics on the planned follow up/treatment schedule. We have seen positive results with ants immerging from the site and dying.
