Clean the house seasonally or whenever a family of birds vacates the premises: Remove all nesting debris and rinse the house with a sanitizing solution of one part bleach and nine parts water. Rinse the house again with clear water, and allow it to air dry thoroughly before storing it for the winter or repositioning it for new tenants. Nesting birds face many different hazards, but there are easy ways to make any bird house design safer and more attractive to bird families. Building a bird house may seem like an easy project, but there is much more to an attractive, bird_friendly house than a wooden box with an entrance hole. Before you build a bird house, you need to understand what nesting birds need and how best to meet those needs with the house you construct.
Snags provide ideal feeding sites for woodpeckers as many insects live and reproduce in decaying wood. Many snags are covered with small holes made by foraging woodpeckers. Though woodpeckers have powerful bills and neck muscles, they are only able to excavate nests in trees with soft decaying centers. Thus, dead or dying trees are preferred excavation sites. Unlike most other cavity_nesting birds, woodpeckers rarely use birdhouses. 22
