Ex-wife Asking People To Take Pictures Of My House.

I am residing in Texas, my ex wife has asked multiple people to come to my house to take pictures. First it was my children, then my brother and last an old friend of mine. There is nothing wrong with my house, I don't have drugs and all of my guns have locks. I feel like she is going to try to amp things up because in a year she loses 50% stake in the sale of my house. Is there anything I can do to keep her away from my house? Or maybe have her for harassment? I don't know where to go from here.

For more clarification, she asked my 10 year old to do it and he told me about it and said he did not like that.
