Bug Bombing House's Crawlspace

I read a news story several years ago about someone having set off several of them in a cellar, all at the same time, and at that time (and maybe still) they used propane as a propellant. The gas hit a gas stove pilot light flame or a spark and the house blew up.

Sorry no cite, but might be googleable.

The Mythbusters covered this one. While it is possible, it’s unlikely. Still, precautions should be taken: turn off all gas pilot lights, for example. Best bet: read the directions.
