Yes. Most parasites are avoided by raising your vibration to take yourself out of thier level, and then they can’t see you and you can’t see them either.
You can do this with intention, and surrounding yourself in a bubble of white-gold light. Emit the emotion of joy from the solar plexus (middle dan tian, or heart, either works) as well and that magnifies the effect. I use tis light in smudging as well - it’s the exact same thing.
