I've seen that in Pentecostal and Charismatic churches while doing (what I would call a type of) exorcism some claim to smell the demon. They express the smell as "sour" or something rotten.

[Bible Knowledge](http://www.bible-knowledge.com/signs-of-demonization/) describes the smell as putrid and toxic and also like burning sulfur.

[Oral Roberts](https://en.wikipedia.org/wiki/Oral_Roberts) claimed he could smell them in a person, and [Tom Brown Ministies](http://www.tbm.org/role_of_demons_and_sickness_by_t.htm) says it's type discernment.

According to [Let Us Reason](http://www.letusreason.org/popteac17.htm), Joyce Meyer described the smell as a "stench."

**Is there any biblical scripture that explicitly or implicitly suggests that demons have any odor?**
