Hello! So today, I went out to the duck run for their daily pool water cleaning to find swarms of flies. Like clouds it seemed like. I think part of the problem is that the run has really fine mesh so any bugs that get inside struggle to leave.. I’ve already hung a fly trap and purchased a couple more. I sprinkled DE around the run. What else can I do to address the issue (aside from the obvious try and keep the coop clean) I think part of the problem is the daily tipping of the pool water but I’m not sure if that is avoidable. Thanks in advance for your input!!
