Usually some positive enforcement works as well

And show them, when you don't like something, but a spray bottle is harsh

My 2 little ones are only allowed on some parts of the balcony (because they could fall down)
If they do stupid things, they just lose their balcony privileges

If they do something stupid inside, they'll get locked out of the room (usually 5mins is enough) and they'll learn it after time

The best way to train cats is to get them to love you as well. They don't want to be separated or you being sad/angry with them.

No need for harsher stuff
