Deer Fly Traps

Step 6: Homemade hanging sticky trap

The assembled hanging trap. The bag's plastic ties are tied together loosely to keep the bag from riding up over the bottom of the wire cage. Sun warms the black bag, and wind makes it flutter. The wire cage inside keeps the wind from thrashing the bag to shreds and keeps the bag from blowing up and getting stuck to the sticky cup. A hole is made in the cup's bottom using a hot soldering pencil, and the cup is supported by a stopper knot in the string, high enough so the cup can also be moved by the wind.
