If you haven't gotten your box up yet and are looking for a supplier "Natures Remedy" In Paso Robles, California supplies all of the materials, installation and the maintenance of their nesting box for the life of it for one price.
If a box lasts 10 years and is cleaned out once a year that is $250.00 right there.
It has been studied and the nesting box will pay for itself in one year from the time it is occupied.
That gives you at least nine years of FREE ENVIRONMENTALLY SAFE RODENT CONTROL 365 NIGHTS A YEAR! :)
They are a conservation project and a business. Their motto is "The reason we maintain the boxes is so that they remain usable year after year and we can build the barn owl population back up by providing safe habitats in which they can raise their young.
