About three years ago my neighbour started producing his own compost. Initially, the smell was bearable, but it appears that he has ramped up his composting and is bringing in manure as well. I suspect he is even selling or supplying to others. The smell has become unbearable and pervades our entire house and garden, even with the windows closed. We really can’t stand it anymore. I’ve asked my neighbour to stop but he just ignores us. Is there anything we can do?
