Trapping is a addiction man! It is a ton of fun. anyways....
I use #3 spring coil traps for coyote, and #2 spring coil traps for anything that weighs 10-20 pounds. You can go out and spend $8 on lure but I have had as much or more success making my own lure,
bacon grease is one of my favriots, but I have used tuna fish, rabbit intrails, or you can put all those together + a mouse or two, stick it all in a blender blend em together and put all that good stuff in a airtight container and it is ready too go! You can blend just mice too.
Rotten eggs work good and so does stinky meat. You will just have to figure out what works best for you and it also depends what you are trying to trap. for exmpl...... coyote= rabbit guts- blended mice, coons= tuna fish....etc. When setting the trap you gotta think like the animal For example... " if I am a coon I will probaly wanna step here and here" and so then thats where you place the trap. Or you can make it so the coon has to step on your trap, by putting pointy rocks all around it, or placing the trap in a clearing surrounded by brush, or place your lure under the trap and put a thin layer of leaves and dirt on your trap so the coon has too dig for the lure and in the process their is a 90% chance it will get caught. I learned alot by just typing my questions in the google search engeine as well.
Have fun!
