Bird Control Services - Customized One-Way
To safely remove the birds, we customized a one-way device and are going to install it over the bathroom exhaust vent. The bird can push this flap open when it exits, however, because the flap is weighted, they'll be unable to reenter the vent. The best part of this device is that, if there are young birds inside, the adult female will still be able to feed them through the flap, until they leave.
