I think you can just empty and clean the box. It helps keep the parasites down. Hopefully the wren won't go after that box. Good Luck!!

> My pair's first brood fledged today - so exciting!! I wanted to get some more seasoned bluebirders' opinion on whether I should clean out the nest box now or not. I feel like this would be a no-brainer, but a male house wren showed up for the first time ever on my property about 4 days ago, and seems like he's planning to stay. He's been singing outside our bedroom window for the past few mornings at 5:30am (ugh!) and I saw him moving some sticks into another box yesterday.
> If I clean out the box the bluebirds used (which they also chose last year) am I setting it up to be taken over more easily by the wren(s) or are they going to do that they're going to do, regardless?!
