Deer Fly Traps

Step 3 Horse Pal trap hanging loop

I used three lengths of plastic pipe to form a loop for hanging the trap. Exchanging plastic pipe for the trap's metal parts made it light enough to hang from a tree limb. Flies "escape" up through the wire screen funnel, cannot figure out how to get out of the jar. Very few other kinds of insects get into this trap, no beneficial insects. The dark granular band around the mouth of the upside-down plastic jar are the remains of about four weeks' catch of deer flies.
