It would be interesting to run a computer simulation (something an engineer would do) to see what the cost of using chemical insecticide is on a cattle operation. Besides the cost of using the insecticide itself, you have the added cost of undoing the damage it causes.
Once you start using it for something, the tendency is to continue using it. Then you lose your beneficials that had a job to do and you have to pay more money to do what they used to do for you. Dung beetles and the beneficial flies that decompose manure are extremely important to the soil fertility so you don't have to pay for continued use of fertilizers. Once you have used an insecticide, you are on the Dark Side and can't get out.
I have a sense that the use of chemical insecticides is the single biggest drain on net profit that a cattle operation can employ.
If you want to find a source for dung beetles, do an Internet search for Dr Pat Richardson at UT Austin. She's studied them for years and gets them from somewhere. You know there are different species of beetles for different cattle. The African cattle have different beetles than the Asian than the European than the American bison/elk/deer/sheep. I don't know what you need for, say a brangus, but Pat would.
I watch the dog poop in the yard and neighborhood. In the chemical program yards, those piles stand up proud for a week looking drier but still basically the same as the day they were laid. Eventually the grass grows up around them and they get mowed into oblivion. In the organic yards and my own, my dog's poop is covered with flies and roley polies almost immediately. After a day it has a definite slump to it and is starting to lose form. After another day you can hardly tell what it used to be, and when I step in it (yuck), it doesn't stick to my shoe (voice of experience). Two days later it is completely melted into the soil and you can't find it again. I LOVE organics!
