I think my maid is practicing black magic on my family. What things should I be looking out for? She is Filipino.

I have ever experienced my helper doing black magic on my family. SHe was from Indonesia. We sent her back home immediately. She used to have lots of glass and photos of the family stored in her bags. and she had these small dolls - like voodoo dolls with pins in it. It was very very scary. Could not risk it so sent her home immediately. I also learnt that helpers from west java, quite a few practice this. Better get from myanmar or sri lanka.
