Wish I’d seen this info a bit earlier….
like before removing the nest from my Bluebird house a few weeks ago! They say it’s called “Spring Cleaning” for a reason, and not wise to clean houses in fall. By leaving nesting materials in a wood birdhouse over cold winter months, it helps to reduce bird parasites by allowing the birds’ own natural defenses against them to develop.
Woodpeckers and others who do not gather their own nesting materials may be enticed to these nesting sites as well. So, next time you’re ready for spring cleaning…wait until spring!
