Hello Gerald! Today I was here to perform your one time service! First I inspected the door and from the picture you showed it that they were carpenter ants. I applied an ant gel bait in the cracks and crevices of your door. I placed carpenter ant granular in the corners next to your door and applied two different liquid treatments one inside by the door and doorway and on the outside. Please allow 2-3weeks for product to be most effective! Thank you for choosing Green Pest solutions!
