Can I get an injunction or a PPO against my neighbor who has trespassed on my fenced property several times?

My neighbors and I have a "history" of not getting along for the last five years. It all started with an initial noise complaint where I asked them to quiet down and when they did not, I called the police. Since that incident, I've had trash thrown in my yard, a new city-issued garbage can stolen, cable wires cut, dead fish added to my trash can, more loud music incidents, a barking dog sent over to my fence at 3 o'clock in the morning, and numerous other annoying ignorant things. The thing that's really getting to me is that since I have installed my six-foot privacy fence, they have entered my property twice now without my permission. Please help. Thanks.
