Same story as most of the other threads.

Next door neighbors don’t care that they are a disturbance to the neighborhood.

Moved into our home about 3 years ago, we share a fence line in the back yard and a property line in the front yard. I came home one day to find his lawnmower trailer in my yard. The trucks rear bumper was on the line, but the whole trailer was in my yard. After a polite conversation, he said he would move it. Weeks later same thing. After the third time, I planted some small privacy hedges about 5 feet inside the property line. Baffled, he asked why I planted those. Last year he cuts my bushes which are still inside the property line and almost kills them. I remind him the severity of tree law.

Every night of the week they sit on their screen porch in the backyard and watch TV/listen to music/hang out. I’ve got no problem with that. It’s the late night partying, screaming conversations, TV volume at 99 that bothers the rest of the neighbors.

We have tried communication channels, and even local law enforcement when things run past midnight. A relative works for local PD and gets them out of the tickets. Law enforcement calls will shut them down for the night, I just want to make their experience sitting on their porch unenjoyable.

I don’t want to do sounds, unless maybe like annoying frequency but can’t be pinpointed coming from my house. Or smells that have an actual use case I can vouch for.
