Pest Library » Cellar Spiders

Size:

Up to 3/4-inch in body length with an extremely thin shape.

Color:

Pale whitish or cream.

Behavior:

Cellar spiders spin large, tangled webs and hang upside down within the web. When disturbed, they shake the web violently. They are not dangerous spiders and actually are quite beneficial in that they have been known to capture and eat other spiders, including even black widow and brown recluse spiders. Once their web becomes old and unusable, cellar spiders construct additional webbing attached to the old web. Over time, considerable amounts of cobwebs can accumulate.
