Things You'll Need
1/4-inch wire mesh
Wood stove spark arrestors prevent sparks and embers from exiting the stove pipe of a wood stove, helping to prevent accidental fires. Building your own spark arrestor out of common wire found at a hardware store is quite easy to do. By following a few simple steps, you can save not only a forest but potentially thousands of homes.
Measure the diameter of the end of your stove pipe.

Measure and cut a piece of wire mesh as long as the total perimeter around the pipe and 8 inches tall.
Roll the mesh together and use the wire and pliers to "stitch" the edges of the wire mesh together to make a cone.
Slide the cone over the top of the stove pipe prior to lighting a fire.
Spark arrestors are not as necessary during the winter months, but are highly recommended, if not required, during the summer months.
