Crews were called to a home on Arthur Street around 10:30 p.m.
They say a plastic shed, fence and trees caught fire. A mini van in the driveway sustained heat damage.
No dollar value yet attached to all the damage.
That's prompted some safety tips from Niagara Falls Fire:
-always have adult supervision
-follow label / use common sense
-have water handy
-light one firework at a time
Better yet, Niagara Fire says leave it to the professionals and be safe
