Firefighters are called to plenty of accidental blazes but this is probably the first one they've been to that was started by a spider.
Emergency services rushed to an apartment fire in the northern California city of Redding on Sunday after a man's spider-killing abilities went haywire.
The fire started, according to witnesses, when a man had been attempting to kill a "huge" wolf spider with a blowtorch.
When the spider caught on fire, it scurried to a nearby mattress, which quickly went up in flames.
Despite trying to put out the fire with a garden hose, it quickly spread to curtains and a flag collection, forcing the evacuation of the entire building.
