It seems the kids let her in. Can you realistically stop them from letting her in? Would you want to? What kind of message does "Don't let her in" send to them?
I can't remember the details of your sitch, but is your house the marital home, where she still contributes to mortgage payments?
Can the kids let you in to her place if you stop by there unannounced? (Not that you'd necessarily want to)
Maybe just send her an email that says "In the future, please let me know when you will coming to the house."
