A man appears to have set his parent's house on fire trying to kill black widow spiders.  Firefighters were called to a house on Tuesday in Fresno, California, where this guy was house-sitting for his parents.   He used a blowtorch to kill the spiders.  He got out safely, but the attic and second story were damaged.  There's no report on the spiders!  Sounds like a scene out of a Halloween movie.
