We had a large duck pond growing up. Lots of resident ducks and geese. My uncle used one of those Havahart traps to catch coons and possums. After capture, he would throw the trap into the pond for about 20 minutes. Worked great!

pour some dog food in your back yard and leave it there. stand on your padio porch whatever (even inside your house and shoot through a window etc) and wack em with your bow. Note other "baits" will work but dogfood smells so they pick it up faster

I trap em mostly, but I have also shot em and sicked my dogs on em.

and... I am pretty sure thats illegal.
