We have a nest of wasps living in the outer wall of our house. When we tried to close off the opening, we irritated the colony and my 3-year-old daughter was stung. So we asked for professional help from Abell. The lady on the phone was very friendly, and the technician who came over was very experienced. It's a month now a month after the service, we hardly see any more wasps in the area, and we are covered for another 2 months if we see a problem, which is reassuring. Overall I'm happy with the service and the result, and I'd happily refer them to others.
