Earwigs have infested my chicken coop. It has a metal tray you can pull out to change the bedding and when I pull it out there are 100's of earwigs underneath. I do DE mixed in with the shavings but this hasn't made a difference and I hose it out once a week. I am not sure it will harm the chickens but it is really gross. What can I use that is safe for the girls??? PS I hate earwigs.
