An American family has been driven from their suburban St. Louis home by thousands of venomous spiders that fell from the ceiling and oozed from the walls.

Brian and Susan Trost bought the home overlooking two golf holes in Weldon Spring seven years ago and soon afterward started seeing brown recluse spiders everywhere.

Susan Trost says she'd dodge spiders falling from the ceiling while she was in the shower ... and in 2012 spiders started bleeding out of the walls.

At least two pest control companies were unable to eradicate the infestation.

An expert estimated there were between four and a half thousand and six thousand spiders in the home.

This week it was covered with tarps and workers filled it with a gas that permeated the walls to kill the spiders and their eggs.
