Okay 2 warm days and we have a hatch. Has anyone used those parasitic wasps to control flies? It seems to be the way to go if you can't use natural sprays or afford the expensive barn systems like me.

I know of a friend who uses a homemade forumla of herbs I contacted him to tell me the formula so I can share but you know how friends are when you want something back in return for letting them use your trailer to move!

Oh well let me know any input from those wasps.
