I have have my girls for a little over a year now, they have a small coop and a large run. Recently I have noticed that there are loads of small black ants in the coop as well as flies, wasps, and others in fewer numbers. The ants almost seem to be living in the walls of the coop and I have no idea how to get rid of them! I’ve tried diatomaceous earth and it doesn’t seem to faze them. Does anybody know how to stop these insects?
