A pellet gun works well on them. I had them nest in my front yard and come back for a couple of years before I got rid of them. They had a huge nest up about 40' in the top of a pine tree next to my garage. They would take off from the nest and swoop down along my driveway- splattering my cars with huge piles of crap. I got sick of this crap. LITERALLY. I stood out in the front yard with my pump-up Crosman pellet gun with a 4X scope one day and waited for them. When they stuck their heads over the side of the nest to look around, I shot them under the chin. They'd stagger around and then fall out of the nest to the ground. I got three the first day, thinking I had gotten them all. But I noticed the last one the next day and got him, too. They never came back. Prior to getting these I noticed one out in my back yard, high up in my maple tree about 40-50 feet. I went in the house, pumped up my pellet gun and nailed him. He was dead when he hit the ground. When I measured it from my deck to the tree it was about 125'. And at least 40 feet up. Not bad for a little pump up Crosman. I still see them flying around but they never seem to fly over my house. Next to rolling Irish Setters up in the wheelwell of a car, I can't think of anything more nasty and fun to dispose of............Denny Crane
