A: The "muck" at the bottom of your pond is a great breeding ground for leeches. So the absolute best way to get rid of them would be to get rid of the "muck". Pond-Clear Natural Bacteria is the best way to do this. Pond-Clear will eat up to 5" of "muck" per year!
Another thing you can do in the short term is trap them. Do to so, do the following:
1.) Start with a coffee can with a plastic lid
2.) Poke holes in the sides of the can with a nail. Holes should be 1/8 to 1/4 inch in size. The nail holes should leave a sharp burr on the inside of the can (approximately 50 holes).
3.) Put about 1/4 cup of raw meat in the can (ground beef, liver, chicken or turkey giblets are recommended).
4.) Put the lid on the can and submerge it completely in your pond. A rock placed on top of the can will prevent it from falling over and will help prevent snapping turtles from tampering with it.
5.) Check the trap a couple of times a week and remove the leeches. Keep the trap in the pond until the leech numbers decrease, or you no longer catch any leeches in the trap.
