This is probably one of your biggest nightmare! 100 Millions of Spiders Create 4-Acre Spider Web in Baltimore! Can you imagine this?
Or you can also take it the other way! How many critters must be crawling around that place to keep 100 million spiders alive? OMG!
This extreme spider invasion was obserbed in Baltimore Wastewater Treatment Plant in 2009. The spider web covered an amazing 4 acres and scientists estimated that an amazing 107 million spiders were living in there. Imagine 35,176 spiders per cubic meter crawling over your head!
This spider infestation was so incredibly out-of-this-world that scientists even reported it in a scientific paper:
Greene, A et al. (2010). An Immense Concentration of Orb-Weaving Spiders With Communal Webbing in a Man-Made Structural Habitat (Arachnida: Araneae: Tetragnathidae, Araneidae). American Entomologist, 56 (3), 146-156.
And what these scientists write in their publication is unexpected:
We were unprepared for the sheer scale of the spider population and the extraordinary masses of both three dimensional and sheet-like webbing that blanketed much of the facility’s cavernous interior. Far greater in magnitude than any previously recorded aggregation of orb-weavers, the visual impact of the spectacle was was nothing less than astonishing. In places where the plant workers had swept aside the webbing to access equipment, the silk lay piled on the floor in rope-like clumps as thick as a fire hose.
Well, the best thing to do is:
OMG! This 4-acre spider web may be the grossest thing you have ever seen on Halloween!
