Marvin was very polite and very thorough. He took the time to explain what was being done and what we needed to do to keep our pets safe while the spray is drying. There were only two rooms that he could not do (we still are unpacking boxes from our move). If needed, we will call back. Our main concern was with the outside perimeter of the house as there is a heavy ant population. He also treated a large wasp's nest that we had not noticed.
