How to Make a Spark Arrestor

Explore America's Campgrounds

Stove spark arrestors are devices that fit over the chimney of a woodstove or fireplace, and keep embers or sparks from entering the air; causing fires elsewhere. The embers are caught by the wire mesh of the spark arrestor and either burn off or fall back into the fire. Building a simple and inexpensive spark arrestor can save you alot of headache in the long run.

Items you will need

  • 1/4 inch wire mesh

  • Pliers

  • Tape Measure

  • Wire

Use the tape measure to measure the perimeter around the end of the stove pipe.

Cut a length of wire mesh that equals the perimeter and is 8 inches tall.

Roll the mesh into a cone shape and use the wire to "stitch" the edges together.

Slide the cone onto the end of the stove pipe prior to starting a fire in the stove.


  • Always use spark arrestors during the Fall and Summer months to avoid starting forest fires.
