You did a wonderful job!! We had what we thought was probably a small carpenter ant problem inside the house, occasionally killing a few, but finding them steadily everyday. We thought they were coming from the hot water radiator and put some gel there. A few died, but still, everyday we were finding more around the house, here and there. Until we looked at the light fixture and saw many moving inside, and understood they were coming from the ceiling. Well, we called you, you went in the attic and found a huge nest, and totally exterminated it. But you knew where to look, what to do, and that was amazing. No more issues, and we are so thankful and relieved! They know what they are doing, there's a lot of experience there.
