Marbled Cellar Spider: 15 Facts You Won't Believe!

Discover the most exciting marbled cellar spider facts you will ever read.

These long-bodied cellar spiders are unique because they have two different kinds of silk, one kind for catching prey and another to help keep themselves from getting stuck in their own webs! They weave a strong silky barrier around their nest or home so that when it starts raining hard outside there is little chance of them drowning inside as a result of flooding water coming through cracks in the walls. The female spider will also protect her eggs by wrapping each egg with an individual protective layer made out of her tough silk threads. Did you know that she lays about 150-200 eggs at once? These spiders are pretty docile as they don't have any venom that will cause harm to humans or animals, but their bite can still be painful enough!

These spiders are known for spinning webs in the corners of buildings. Some people find that quite cool, while others would prefer not having these critters around at all times! The long-bodied cellar spider is easily identifiable by its distinctive markings and coloration, and it has long been popular as an exotic pet due to how relatively easy it is to care for this critter.
