Black Mold and the New Netflix Series “The Haunting of Hill House”


October 30, 2018

Toxic mold plays an important role in the popular new Netflix series “The Haunting of Hill House.”

Episode 7 of the show is largely devoted to the topic of the homeowners’ attempts to fix the mold problem that is found to be hidden behind the walls in the home.

Later, the mysterious “Red Room” is found to be filled with black mold.

While some have suggested that the mold was created by the evil spirits present in the house to prevent the family from being able to sell the house and move away, others have argued that the mold in the house actually could have been responsible for all the events that occurred in the story.



For instance, a video about the topic by the You Tube horror channel Deffinition proposes:

By the end of the show, we are all convinced that the experiences that the Crains have had are real and that the house itself is a paranormal entity and is hell-bent on making them suffer. But what if there’s a completely plausible explanation for the events that happened in the show? What if the one thing that is present throughout is causing the Crains to believe they are being haunted? While we never get concrete confirmation that this is the case, it seems completely likely that the mold that festers throughout the house may in fact be causing all of the hallucinations and problems….

What I love about the show is that it works either way. The best ghost stories always offer a way for skeptics to put the events aside 


A Reddit thread (in the Fan Theories section of the site) also discussed the possibility that mold was responsible for the problems in the house.

The idea that mold may be at the root of some haunted houses has been considered by some academic researchers and has received some media coverage in the past.

The topic is also discussed in the Paradigm Change blog article “Did the Mold at Grey Gardens Affect Big Edie and Little Edie Beale?”

Regardless of whether viewers believe that the mold in Hill House was responsible for all the events that happened in the story, the new series does take the health effects of toxic mold very seriously and suggests that for homeowners, the thought of having a bad mold problem take over your house can be a truly terrifying one.
