We have lots of chickens, pigs, and a few cattle. And a frightening number of FLIES! I've just released 25,000 fly predators around the pig lot, chicken yard, dogs' yard, and near where the cattle like to hang out. And I have another shipment arriving today. Hoping these will make a dent in the fly population! Meanwhile, I've also been looking into using ag lime to control the odor and flies in the pig pen, where they are the worst. And it just occurred to me (dummy!) that if ag lime kills flies and fly larvae, then it will also kill the fly predators! So now what?
