The History and Background

New Orleans has long been a city of mystery and intrigue, but perhaps none more so than the 1987 incident at the Old Ursuline Convent on Chartres Street. This seemingly unassuming building had an unexpected and terrifying encounter with poltergeist activity that coincided with a massive spider infestation. The events unfolded in late October and early November of that year, leaving residents and investigators baffled by the dual occurrences.

Key Events or Sightings

On October 23, 1987, Sister Mary Josephine Lefebvre, a nun at the Ursuline Convent, noticed an unusual number of spiders in her quarters. The spiders were not just a few; they quickly multiplied to hundreds within days, covering every surface—furniture, walls, windows, and even food. The infestation was so severe that Sister Mary had to abandon her living space.

As the spider problem worsened, strange phenomena began occurring throughout the convent. On October 30, Sister Mary reported seeing a large, black shadow moving around her room, which she described as “like something out of a horror movie.” On November 2, the nuns heard loud banging noises coming from the ceiling and walls, followed by a sudden drop in temperature.

Witness Accounts or Evidence

Sister Mary’s account of the events was corroborated by other convent residents. Sister Ann Marie recounted hearing the same banging sounds during her night shift on November 1, which she described as “loud enough to wake anyone up.” Additionally, several nuns reported seeing small objects levitating and moving around their rooms. During one particularly intense period, a Bible reportedly lifted itself off the shelf, flew across the room, and landed next to Sister Mary’s bed.

The infestation was also documented by a local exterminator who visited the convent on November 10. He noted that the spiders were unusually aggressive and seemed to be moving with a purpose, not just scurrying randomly. The exterminator estimated there could be tens of thousands of spiders in the building.

Investigations or Research

Local paranormal investigators, including members of the Ghost Hunters Society (GHS), began investigating the convent shortly after reports emerged. They set up cameras and equipment to capture any evidence of poltergeist activity or unexplained phenomena. Over several days, they documented everything from strange noises to sudden temperature drops and light fluctuations.

The GHS team also collected spider samples for analysis by entomologists at Louisiana State University (LSU). The scientists confirmed that the spiders were a species native to the region but noted their unusual behavior—aggressive and highly organized. Some researchers speculated that these spiders might have been acting under some form of external influence, possibly due to electromagnetic interference or unexplained energy fields.

The Current Status / Ongoing Mystery

Despite extensive investigations by both paranormal and scientific teams, no definitive explanation for the dual phenomena has emerged. The poltergeist activity ceased as suddenly as it began, leaving behind only a trail of questions. Some investigators believe that the spiders may have somehow become part of an unexplained energy field, causing them to behave in strange ways.

Frequently Asked Questions

Q: What exactly caused the spider infestation at the Ursuline Convent?

A: The exact cause remains unknown. While some researchers suggest that external factors like electromagnetic interference could have affected the spiders’ behavior, others point to a more supernatural explanation involving poltergeist activity. No conclusive evidence has been found.

Q: Were any scientific studies conducted on the spider infestation?

A: Yes, LSU entomologists analyzed samples from the convent and confirmed they were a native species but noted their unusual behavior. However, no definitive link was made between the spiders’ actions and poltergeist activity or any other unexplained phenomena.

Q: Did the poltergeist activity continue after the spider infestation ended?

A: The poltergeist activity ceased abruptly on November 10, coinciding with the end of the spider infestation. While some investigators noted that the temperature fluctuations continued for a few more days, no further incidents were reported.

Q: Have any paranormal investigations been conducted in similar buildings since then?

A: Several other buildings have experienced unexplained phenomena and insect infestations, but none as dramatic or well-documented as the Ursuline Convent incident. Some researchers continue to monitor such cases, looking for patterns that might shed light on the 1987 event.

Q: Is there any ongoing research into this case?

A: Ongoing research focuses more on understanding poltergeist activity and spider behavior rather than re-investigating the Ursuline Convent incident. However, some paranormal enthusiasts continue to revisit old cases like this one in hopes of finding new insights or evidence.
