![To make a drilled wood nest, drill a 3- to 5-inch hole in untreated wood without going all the way through the wood. Then, drill a variety of hole diameters, from one-quarter of an inch to three-eighths of an inch, all approximately three-quarters of an inch apart. Holes that are smaller in diameter should be 3 to 4 inches deep, and holes more than one-fourth of an inch in diameter should be 4 to 5 inches deep.](https://secure.caes.uga.edu/news/multimedia/images/2756/DrilledbeenestLR.jpg)
