Eiliya Maida was using a propane blowtorch to get rid of spiders in his back yard Saturday when he unknowingly set dry plants on fire, the Chico (Calif.) Enterprise-Record reported.
The flames quickly spread to the attic of Maida's home.
Maida's brother-in-law, George Basbous, said he noticed smoke rings from the top of the house.
"And that's when I went crazy," Basbous said. Basbous called 911 and emergency responders were sent to the house.
Firefighters put out the flames, which did an estimated $25,000 worth of damage to the home.
No injuries were reported.
