Someone said the following to get rid of squirrels in my backyard:

"Here's an effective way of getting rid of the little monsters. Although inhumane, it is effective: Fill a 5 gallon bucket halfway up with water (we'll call it the pool) and cover the pool with sunflower seeds (they float). Then lean a board against the bucket going from the ground to the top of the bucket (diving board). Have a few seeds sprinkled leading up the diving board. That's it. They see all those seeds and them greedy lil varmints can't resist. They jump in but cant get out. One after another they'll jump in."

Does this really work?
