All, With the help of a combination of Gilbertson and Van Ert nest box sparrow traps, I have been able to successfully combat house sparrows trying to drive the bluebird pair away from my nesting boxes. It is an on-going battle, but I feel I now have the right tools. I have also located some great sources for ground style house sparrow traps.
Please email me if you need such information. Matt Baumann Winona, MN
