Take one piece (1" × 16" × 16") and find the center, using a radius of 8" to make a circle for the bottom of the trap. Then use a radius of 6" to make an opening in the bottom on which the cone fits. An opening of 1" × 2" is made at some convenient point in the bottom of trap through which the dead flies are removed. Take a piece of wood (1/4" × 1-1/2" × 2-1/2") and make a cover to fit over this opening. Fasten it on the bottom with a screw so that it may be easily turned. Make the cone of a piece of wire netting 10" wide. It must fit the inside circle in the bottom as shown in the illustration. Tack this to the bottom with 3-oz. tacks. The top of the trap is made just like the bottom using the same radius. Cut out 3 places in the top and bottom for the braces (7/8" × 1" × 24-3/4") to fit in. These must extend 3/4" below the bottom and nailed in place with 5-penny box nails. Cover the opening in the top with a piece of wire netting 13" in diameter. The whole frame is then covered with the 24" wire netting.
