They're big, they're ugly as sin and can be mean as hell. They'll come after you hissing if you get near their chicks or their nest.Pic of ducks? What do they do different than the mallards that are milling around?
The answer to you problem is SSS, Shot, Shovel, and Shut up.
I was about the same age when I took one out with a wrist rocket. You know how they fly low across the water and I took aim in a lazy "maybe I'll hit it but hope I don't" kind of way. Hit a big duck square in the neck and he dropped right in the water with a huge splash just like the old WWII footage of our ships shooting Japanese Zeros out of the sky. I ran inside, waiting for the man to come, but nobody did. The big ball of feathers floated out there for about an hour, then finally onto a neighbor's beach.I tried handing one a Ritz cracker and it bit the hell out of my hand. Hell of a bite. Made me see stars. I was about 10 years old at the time and impressed myself by not kicking it in front of smaller children.
We thought another neighborhood kid was a degenerate because he used to "catch" them with his fishing pole and close the bail when they were mid flight. Sounds like he was actually solving the problem while the rest of us were feeding it.
No kidding. Get a blade and get to it!8 ducks, one sling blade, 5 minutes of elbow grease and then use the waterhose as needed. The end!
Get a short 2x4 board or if you have a stump close by that is fine too.
Lay your hatchet next to the 2x4 or stump.
Take a metal clothes hanger and straighten it out except for the curved end (like a cane).
Pretend it is chicken killing day back on the farm. Or Thanksgiving. Whatever makes you more comfortable.
We've tried everything. Its a female duck with 7 adolescents. Ive tried sprays, noise, water hose, leaf blower, firecrackers, etc... they will leave but will return when we are sleeping and crap on everything. Florida Fish and Wildlife will not come get them as they are considered invasive. Trappers need a license to trap Muscovvy which increases the cost. I was quoted $100 per duck. The state also encourages people to euthanize the ducks. I will be feeding them some poison corn.
I'll take care of your problem for $50/duck.
