Hi, Well, they (starlings/house sparrows) have invaded big time, and I have found several traps that can be made, but I am not savvy enough, nor do I have any equipment. I have NOT found any to purchase, that make as much sense has home made ones. If there is anyone in the Bonney Lake area, I would love to pay you for at least one Starling house trap. I found one online, where they fall into a tube, or trip a trap door. This has become a huge problem for me, and I have done all I can with changing feeding habits, but they will not leave. I don't want to completely stop feeding my woodpeckers. Please reply offline. Thanks, Vicki Biltz Bonney Lake, WAvickibiltz at gmail.com
