Those whom you describe would get treated to a vile cavalcade of noxious payback.
I did not jest with my protest of using a 25KHz response to a neighbors incessant barking yap machine. The 200 watt rated tweeter horns repose in my PO Box as I write this...
Stink bombs work wonders. But I adore using the scent of LPG odorant. Oil is used in refining to lube seals and this lube oil attracts the odorant. Tip a pot upside down, crack the valve and liquid LPG escapes. So does the oil. Careful placement upwind of the offender does two things. Drives them away. Makes subsequent rehabitation of the site less likely.
MoFo and the So' Bros, mind-numb can be countered with adequate db counter dosage of Luciano Pavarotti. The Barber of Seville is particularly effective. I use Bob Dylan's "Hey Mister Tambourine Man" pointed at an offending neighbor's house when things get out of control at 0300. For some reason Mexicans consider suicide when confronted with adequate volume of this piece while ensconced in the middle of "La Cruda", a bad hangover.
