I discovered a wasp nest at the top of my front balcony. However, the nest was located hidden inside the walls and overhang and was difficult to access. Usually he tries to relocate the nest safely, but as there was no physical nest to move he had to resort to exterminating the wasps. Joe was very professional and started work straight away. Due to the difficulty of locating the actual nest, Joe needed a second visit to completely eliminate the nest, but at no extra cost. He even needed to make a separate trip to get extra supplies (he charges per job, not by the hour); and this was already rather late in the evening. I greatly appreciated his expertise and willingness to go the extra mile to help eliminate my wasp problem.
