This is my last post here so I just wanted to update used frontline and the mites I’ve been BATTLING for over a year are completely decimated and gone I have not even seen one mite on anyone..All my birds are totally fine and it’s been about a month and a few we put too much on by accident but still perfectly okay. Also I did change my bedding a few times recently because of the mites ( before frontline) haven’t changed it since and still no mites... I’m so happy!
