Homemade Fly Catchers

Instead of buying fly catchers at the farm store I make my own.
Take an empty two litre bottle
Put a banana peel into the bottle
Add 1 c. sugar
1 c. cider vinegar
Fill up to the curve of the neck with water. Put the lid on and shake. Remove the lid and tie twine on the neck and tie into a tree.
This will fill up with flies like you wouldn't believe. When it is full just screw the lid on, cut it down and throw away.
This will save lots of money.
These are especially important if you have farm animals. Its amazing how great these work.
