Man sets house ablaze while trying to kill spiders with a blowtorch

His spidey senses weren’t working.

A California man set his house on fire when he tried to kill spiders with a blowtorch.

The Fresno man was housesitting for his parents when he found black widows, ABC 30 reported. The second story and attic were damaged from the fire, but he was uninjured. He was the only person home at the time.

Firefighters have not determined the exact cause of the fire, but it was assumed to be caused by the blowtorch. Fresno Fire Department could not be reached by the Daily News for comment.

Some social media users joked about the man’s method of killing the spiders.

Although people make jokes about setting houses aflame when they find a spider, it is not advised. “Please don't use a blowtorch to kill spiders,” said Fresno City Firefighters tweeted.

This is not the first incident of its kind — earlier in January, a man in Redding, Calif., set his apartment ablaze while trying to kill a wolf spider with a blowtorch.
