Lexington fire investigators believe the house fire, which began around 12:30 Wednesday afternoon on White Wood Flat, was the result of kids burning cattail plants.
Fire officials say once the plants had burned, the kids threw them into a trash can next to the home. The trash can caught fire and spread to the home.
Eventually, the fire also spread to two neighboring homes.
Extra firefighters had to be brought in to battle the blaze so the teams could rotate and take breaks during the high heat and humidity.
Two firefighters were treated at the hospital for non life-threatening injuries sustained while fighting the fire.
