The Rural Voice, 1982-08, Page 16Build -It -Yourself FIy Trap
Trapping adult flies,
particularly egg -laying females,
will give a big boost to your fly
control program.
You'll need these tools: a
measuring tape; a ruler; a
marking crayon; a handsaw; a
screwdriver; a staple gun; a
stapler; tin snips; and a 1/4" drill
with a 9/64" bit.
And these materials:
a container of white glue;
two small hook -and -eye
assemblies (the kind used to latch
screen doors);
eighteen 11/2" flathead screws
(size six);
one piece of aluminum fly
screen, 12" x 36";
one piece of plastic fly screen,
24" x 36'
a twelve foot length of 1" x 1"
lumber;
and a 10-3/8" length of 1" x 4"
lumber, cut lengthwise to yield
one 2" x 10-3/8" strip.
The trap consists of two parts: a
fly -screen pyramid with a hole in
its peak, resting in a cube -
shaped, screen -covered wood
frame on legs. Attracted by the
bait set under the frame, the flies
funnel upward through the
pyramid into the screened frame --
and then can't find the small hole
in the pyramid to escape.
First build the frame. From the twelve -foot length of 1" x 1", cut four corner posts 12" long and
nine cross pieces 1012" long. Drill holes in the corner posts as shown. When you're finished, you'll
have two posts with four holes and two posts with five holes.

3. The four sides of the pyramid are 91/2" x 91/2" x 12" triangles. Draw them on your piece of aluminum fly screen, as shown, adding a half inch flange to
either side of each triangle. You'll connect the triangles by their flanges. Cut out the triangles with your tin snips and then snip away the top one-quarter
inch from each triangle. Bend the flanges at right angles to the triangles --you can fold them around a straight edge such as a ruler.
