"It's burn is worse than it's bite"

Arachnado 2: Flaming Spiders

Just when you thought it couldn't get any worse, the Arachnado has returned, this time as a "Firenado" with Flaming Spiders. It's up to a renegade Sergeant Preston and the Janitor from the original film to overthrow the corrupt Lieutenant Gallagher and put the fire out.
