I think the best thing you could do is create a Sim with the appropriate traits. If you select one of the "Deviance" aspirations when creating a Sim, you get the Dastardly trait (which is a Sim that is more successful at mean interactions), then select Mean, Evil, and then the last could be slob or maybe erratic. Then make more Sims to be part of your household that are similar to this, with different Deviance aspirations, where maybe the 3rd trait is negative but different (kleptomaniac, ect.) If you create a few Sims like this, you should end up with a family that the entire neighborhood will not like. Another thing you could do is move your trash can around and then knock it over. This will leave trash plants all over your lawn. Not sure if this will produce the desired effect but thinking it might. Aside from calling or visiting in the middle of the night, that's all I got.
