In spite of efforts of cats and dog, the sparrow population in the barn has continued to grow. There is a loud rush of wings as the things head from the feed set out for the chickens, etc., to the barn rafters when I open the barn door. I think they are consuming more than their fair share. They are sitting by the feeders on the back porch and staring in the windows, willing me to hurry up with the chow (chow time doesn't start until next month). So--trip to farm store did not provide with eradication solution I am willing to use. Caulk-type tubes of sticky stuff to entangle them until I can collect them and dispose of them. Have hated sticky traps ever since first using one for whatever was raiding the garden and catching a little finch that was so hopelessly imbedded I couldn't peel it off and had to kill it. Well, that is the idea, I suppose, but if killing is necessary, I don't want to be directly involved. B-B gun? Not a good idea in a metal pole barn. Poison is out. Trap, like a Hav-a-hart?? Farm store did not carry them. Anyone know of a source? Or of a source of plans to make them?
