Homemade Fly Trap

Homemade Fly Traps Cut a plastic 2-litres soda bottle 1/4 down from the top. Invert top portion into bottom portion. Punch 4 holes at top, tie string (twine) to hold both portions together and hang. Add hamburger or fly bait (I filled the trap with 1" of sugar water and added a piece of ham.). Most flies are too stupid to find their way out!
