I live in the country, and I do not see a problem with my neighbors mowing nightly between 5-8pm. Have you talked to your neighbor? Do you know for a fact that they do not work during the day? Maybe they are a school teacher with the summer off, or maybe they are a farmer? The heat can be hard on individuals mid-day. Maybe they have a health condition or are trying to avoid heat stroke. I would rather my neighbor mow nightly between 5-8pm maintaining their yard instead of letting their yard turn into a tick paradise. Maybe you could offer to help you neighbor, or you could move to a city or town. True country folk would not bat an eye at this. Be a kind person and talk to your neighbor to learn their story. Good luck.
