Deal With
Undesirable Birds!

The nests and eggs of HOUSE SPARROWS MUST be removed. House sparrows are not native to this country and are the worst enemies of bluebirds. IF YOU CANNOT DEAL WITH SPARROWS, DO NOT INSTALL BLUEBIRD NESTBOXES. Avoid placing boxes where house sparrows are abundant - near livestock farms or within cities. The PVC nestbox is the most sparrow resistant.

House wrens have become a problem for all cavity nesting birds. These sweet-singing little birds poke holes in other birds’ eggs, and take over nestboxes by filling them with sticks. Avoid areas where house wrens are likely to nest - brushy areas. Install nestboxes at least 300 feet from trees or brush.
