If you’ve experienced problems with Gnats while monitoring your Bluebird nest boxes in 2019 contact us. Let us know what you did to deter them, how often you intervened, what you used and how effective it was. Additionally, if Wrens were a problem, let us know if more so then past years, what kind of nest box(es) you’re using and anything else you’d like to share. We’re working with NABS and others to determine effective detterents for the 2020 season, your input will be very helpful. Please use the link below and THANKS!
