I am really having a tough time with flies.. There must be at least 500 flies in the run that is 14x12 I walk in and they all start flying around.. it is very loud. But anyway I have put in DE, rains everyday for just a few min just to make it wet.. put in two of the fly paper roll strips.. they have some stuck to it.. about 20 or so flies. I bought one of those bag things that you fill with water and it attracts them then drowns them.. hasnt gotten one yet.. I really need something that I can spray or something during the day when they are all out. What can I use in the run? Help please..
