This literally just happened to me Two kids were skateboarding on my property and I found that messed up, at least ask first smh that's rude. So I bang on the door and open it midway and my dad yells "scram you sons of b****es!" In a old man voice I'm probably going to get egged tonight.
Would it not make more sense to step outside and tell them to do it somewhere else because it is disturbing you? If they don't f off at that point call up the cops without telling them, already were told to leave for trespassing.
I just got the idea of taking my old fashioned baseball bat and anonymous mask and running out after them
I dont have a problem with trespassers cause I never been in a situation... But my advice for you is to: 1) get a paintball gun spray em 2) Tell them to f off and threaten them 3) Or do what luckynumber56 said call the cops and they can get arrested for trespassing.
