Fire investigators have come up with an unusual cause of a blaze that damaged a home in Reno - spider killing.

Reno Fire Battalion Chief Rick Kajans says a teenager was using fire to try to kill spiders Sunday afternoon when he accidentally set a fence on fire that then also burned part of his home on Neil Road.

The fire burned through a wall and damaged a kitchen ceiling before firefighters put it out.

Kajans says he doubts the 17-year-old boy will be charged with any crime because the fire is being ruled accidental.
