A massive extermination effort is going on inside of a Missouri home.

It was infested with more than 5,000 brown recluse spiders.

Crews are pumping poison gas into the house to kill the eight-legged creatures.

A family bought the home in 2008 and later found out about the infestation,

The family sued the previous owners.

The home is in foreclosure now.

As for the spider's bite, an expert on brown recluse spiders says it won't kill you, but it'll make you wish you were dead.
