what you can do is make stink bombs very easily. get glass jars(not plastic) and crack 1-5 eggs in it depending on jar size. now pee in it, put milk, put stuff that decomposes that will smell, close it up tight and shake it. now dig holes in the ground and put them in there and cover them now let them stay there minimum time of a week when i did it, i waited a year(lmao) and then dig it up now the point of a glass jar is fumes can escape like in a plastic jar. and then what you do at night is throw the jar at his house like front door hard enough that the glass will break. now when he finds it he will have a stink there minimum a week and he might have stains and will have to clean up the glass!!!
what else you can do is make a stain bomb very simple. you get vineger, tomato sauce berry juice, spices(the more the worse smell it will be) and get it all mixed up then get a funnel and pour it into a ballon and tie it up when he is sleeping throw them at his house walls not pavement. and wait for morning when the sun will cook it. it will permanently stain
