If your neighbor is burning trash, leaves, or debris in their yard, there are a few things you can do to try and stop it. First, you can talk to them about the smoke and fumes that are coming into your yard and ask them to stop. If they don't listen or say that they will only be burning for a short time, you can call the fire department and ask them to come out and talk to the neighbor about the fire code. Finally, if all else fails, you can call the police and ask them to come and talk to the neighbor about burning on their property.
