Playstation5

I keep having random sims come on my sims lot. Not only do they come on my sims lot, but they come in the house and most times I can't get them out. Like when I  click on them there's no option to make them go home. My sims don't even know the people. I have the private lot trait and I have the no trespassing also on the doors and gate. I've also set it as household only  and nothing happens. Some sims still come in or are on the property  using  the grill or water slides, playgrounds and treehouse,etc. Please do  something about  this  because  it's becoming a nuisance.
