If you put it in your paddock dirt it's only a short matter of time before you and the horses (and honey bees, fly predators, ladybugs, etc) are breathing dust laced with sevin (http://pmep.cce.cornell.edu/facts-slides-self/facts/gen-pubre- sevin.html). And gnats and midges don't propagate in dry dirt anyway -- they need wetness (http://www.ca.uky.edu/entomology/entfacts/ef632.asp). You need to move to the desert.
