We have a customer who lives a few houses from a lake. He has geese coming into his yard. I have been asked to try stop these unwanted pests. I read most threads on geese. Flight Control was said to work well but is expensive. Stringing twine on border seems logical in that Geese will not step over anything, but a liability issue comes up if someone should trip. I am thinking that since Milorganite (Human processed sewage) works to deter Deer and rabbits, how about Geese? Garlic cloves on border? What do you think? I have read all the posts about BB rifles, shot guns, heavy surpus artillery and alka-seltzer treats also. All this humor has been enjoyed, I am hoping for some pratical solutions.
