If a fly wouldn't annoy you, would you still scare away the fly after it landed?

What if it wants to lay eggs in you though? I've seen enough bot fly videos. I don't want to experience that.

Being annoyed is only one of the reasons for shying away flies but most times it would be waste of energy and attention.

After seeing how quickly they can lay eggs, yes. I will always swat them away from uncovered food.

Yes, flies are disgusting little creatures. I don't try to kill them but they will have no peace landing on or near me

I am always paranoid about having unknown wounds on my skin. Almost always chase it away, unless I really need to concentrate.

If it's outside, I leave it alone. If it's inside my home, I kill it immediately.
